Want to control budget or have trouble finding clones? Learn how to grow cannabis from seed with this 10-step guide.

How To Grow High Quality Plants

Are you in one of the many states that has legalized cannabis? If yes, then you may have found yourself with a new crop to plant in the garden this summer. Growing a new crop can be challenging even for veteran gardeners, but with a little help from your friends at Impello you can avoid some of the common mistakes that lead to a poor crop.

Pick Reliable Cannabis Seed Banks

When purchasing cannabis seeds, you might often choose the cheapest ones to save some bucks. However, the quality may be compromised, and you’ll end up spending more than you have to. That’s why you should pick cannabis seeds with the best genetics. Conduct your research so that you can buy from trusted cannabis seed banks. Cloning can be a good start too — just make sure to get the clones from reputable sources.

Provide Enough Lighting

One essential element for growing cannabis is proper lighting. It’s not only the quality that will be affected but also the speed and size. While marijuana grown outdoors gets natural light, indoor cannabis needs extra care. This means that your usual lightbulbs are not enough to make up for the absence of lights.

Invest in more premium lights, hoods, and reflectors. Get high-intensity (HID) lights, like high-pressure sodium (HPS) or T5 fluorescent lights. You can also use LEDs to save on energy costs. Just make sure to choose full-spectrum LED lights that allow you to modify the wavelength based on the marijuana plant’s needs as it grows.

Enhance Water Quality

Dissolved solids from water can cause adverse effects on your marijuana plant. For instance, domestic water contains chlorine and fluoride. While they will not kill the plant, maximum yield can’t be expected. So, consider using a reverse osmosis system or filtration. Make sure to change the filters regularly. It’s also best to test the water from time to time to check whether the parts per million (PPM) of dissolved solids remain the same.

Secure Enough Spacing and Ventilation

Wondering how to grow high-quality marijuana? Allow enough spacing between the cannabis buds. Make sure no leaves or branches block the airflow. You can apply low stress training (LST) where you tie the plants down while they’re still young to ensure that the light is well-dispersed, improving the plant’s overall health. Using other tools like filters and fans will also help you maintain the airflow.

Provide Sufficient Amount of Nutrients

One of the 10 steps to growing weed is providing just the right amount of nutrients per growth stage.

Tribus Original is the perfect seedling to harvest cannabis growing products on the market today and it’s very versatile. Usage rates are 1 ml per gallon and with a price tag under $60 for a 250 ml bottle, and a little goes a long way. Because it consists of beneficial bacteria you really can’t overfeed your cannabis plants with it, and it creates stronger plants from the inside out. For best results apply it to your grow media at least once a week. Tribus is compatible with all grow media, including hydroponics and even field application.

In addition to Tribus, these nutrients are necessary when feeding cannabis plants.

Nitrogen, potassium, and phosphorus may be the three main nutrients that your cannabis plants need. However, they also need other nutrients like:

During the flowering stage, various supplements can be beneficial too. These include:

Prune Cannabis Properly

While low stress training does not involve cutting, you have to perform pruning to promote yield increase in plants. It also helps you get rid of buds that are not in their best condition. This way, buds become fewer but larger and healthier. Consider removing the lowest branches to ward off pests. To ensure that the plants recover and grow faster, prune during the vegetation stage.

Keep the Right Room Temperature and Humidity

Cannabis can grow well under several conditions, but you need to ensure that the room’s temperature and humidity satisfy the weed’s needs. Even small changes can affect its growth, so focus on the temperature and humidity in each stage.

Seedling Stage

For seedlings and clones, the preferred humidity levels range from 65% to 80%. This way, they can take up enough water and have stronger roots. In terms of temperature, keep it at 25 degrees Celsius or 77 degrees Fahrenheit during the day and 21 degrees Celsius or 70 degrees Fahrenheit during the night.

Vegetative Stage

In the vegetative stage, moderate humidity levels are necessary. Every week, you can decrease it by 5%. Around 40% to 70% will work. Given that the roots are stronger during this period, they can absorb more water, so lowered humidity levels are preferred. For the temperature, you can raise it a bit — around 71 to 82 degrees Fahrenheit during the day and around 64 degrees Fahrenheit to 75 degrees Fahrenheit at night.

Flowering Stage

Reducing the humidity levels to 40% to 50% is needed during the flowering stage. You can make it 55% but never 60%. Also, the temperature can decrease to 68 to 78 degrees Fahrenheit. Then, in the latter part of the flowering period or one to two weeks prior to harvest, reduce humidity levels from 30% to 40%.

Meanwhile, the temperature can fall between 64 to 75 degrees Fahrenheit or 18 to 24 degrees Celsius with lights on and 16 to 20 degrees Celsius for several nights before harvest. To monitor the humidity and temperature, use a hygrometer and thermometer.

Lowering Temperature

If you aim to lower the temperature, you can do the following:

  • During the day, keep the lights off; during the night, on.
  • Add an air conditioning unit. This can also help reduce humidity.
  • Use a cool tube if you are growing marijuana with HPS lights.

Increasing Temperature

To raise the temperature, you can:

  • Utilize a quality space heater with a thermostat.
  • Use grow lights with higher watts.
  • At the bottom of your grow room or tent, place a heating mat.

Lowering Humidity

If you want to drop the humidity levels, perform these steps:

  • Water your marijuana plants immediately after switching on the lights. Given the quick absorption, humidity levels will decrease.
  • Get a humidifier.
  • Have an airflow fan upgrade to increase the supply of cool air.

Increasing Humidity

Enhancing humidity levels can be possible through the following:

  • Use a humidifier that has enough water reservoir to avoid frequent refills.
  • Using a spray bottle, mist your marijuana plants. However, this shouldn’t be done to flowering plants as it can result in bud rot.
  • Bring larger plants inside the room. Compared to seedlings, they perspire more, raising the humidity levels in the grow room.
  • Consider hanging wet towels inside your grow room.

Maintain Enough CO2

Did you know that providing your marijuana plants with sufficient carbon dioxide (CO2) helps improve their growth by 20%? CO2 is crucial in photosynthesis, where cannabis absorbs light and turns it into energy. Excessive CO2 or a lack of it can be detrimental to your cannabis plants. So, you should know how to provide them with the right CO2 levels. Ideally, it should be above 250 PPM.

To supplement your plants with extra CO2, you can use the following:

    • CO2 generator: To produce carbon dioxide, the CO2 generator burns natural gas or propane. It automatically turns on or off if a certain CO2 level is reached. However, burning the gasses can create heat. So, it’s advisable to use one in a larger grow room.
    • Compressed CO2: With this option, the manufacturer produces the gas and compresses it into a tank. No heat is produced once gasses are released, so you won’t have issues with the temperature and humidity levels. It can also be set to automatic using a controller. Note, however, that both CO2 generators and compressed CO2 can be relatively costly.

    Know When To Harvest the Cannabis Plants

    Harvest time keeps growers excited, especially given all the efforts exerted to produce healthy and quality buds. However, cutting them too soon will defeat the purpose and waste all your hard work as the tetrahydrocannabinol (THC) content will be low. So, harvest them at the right time based on the following indications:

    Dry and Cure Cannabis Properly

    You may think you’re done once you harvest your cannabis. However, drying and curing are important steps to producing quality and tasty buds. First, drying helps reduce the bud’s moisture content to 15%. It also enables you to maintain its taste and the natural compounds in it, including THC. To dry cannabis properly, follow these steps:

    1. Cut down your cannabis plants. While most growers prefer to cut off the branches, some want to cut until the base and hang them upside down. Others will also cut off each bud and then place them on a drying rack.
    2. Trim to remove larger fan leaves. Doing so will contribute to your buds’ improved look. If you’re residing in a place with less than 30% humidity levels, trim fewer leaves.
    3. Begin the slow drying process. A temperature of 65 to 75 degrees Fahrenheit and 50% humidity is preferred. If it exceeds 80 degrees, the terpene content will go away. While hanging the buds upside down is the most common method, you can use a drying rack or cardboard to lay them out. Generally, you need three to seven days to dry the buds well.

    After the drying process, you can now proceed to curing to preserve the plant’s cannabinoids or compounds and terpenes. Simply perform the following:

    1. Put the cannabis buds into mason jars with a wide opening. Other alternatives include plastic or wooden vessels.
    2. Secure the container in a dark and dry area. Humidity levels should range from 60% to 65%.
    3. Check the containers regularly. Open them at least once a day for two weeks. Doing so will remove extra moisture and accommodate fresh air.

    While your cannabis should be ready for use in two to three weeks, keeping it for around two months is recommended for maximum results. Commercial grow operations may prefer to use chemicals to hasten production. However, the whole experience of users may be compromised.

    Conclusion

    There are multiple factors to consider when growing cannabis on your own. However, growing cannabis indoors step by step with our guide above will help you produce quality buds that you’re proud of.

    Growing cannabis in a greenhouse

    The recent explosion in ‘growing your own’ cannabis includes the rapidly growing community of greenhouse growers. For many people, growing cannabis seeds in a greenhouse is simpler than creating an indoor grow room. Greenhouse growers find it easier than growing cannabis seeds outdoors.

    Greenhouses offer protection from the elements, insect predators and grazing animals. Greenhouses also provide a longer growing season. You can plant your cannabis seeds a little earlier than if you were growing outdoors. The greenhouse also protects your plants form the worst of the autumn weather during harvest, allowing you a greater chance of a safe harvest.

    The many benefits of growing cannabis seeds in a greenhouse allows growers in northern European regions the ability to grow high quality cannabis with either feminised seeds or autoflower seeds.

    Cannabis seeds and greenhouses

    Greenhouses can be heated if required. This allows you to optimise the greenhouse environment even if you have unexpected frosts or stormy weather. It also allows you to germinate your cannabis seeds earlier than you might do for an outdoor grow. Read all about how to germinate your seeds in our germination guide.

    With a little bit of thought and planning, growing cannabis seeds in a greenhouse can be a safe, secure and pleasurable way for the home-grower to be self sufficient in recreational or medical cannabis. Greenhouse-grown cannabis is incredibly potent when grown from good cannabis seeds. It’s no surprise that more people than ever are growing in greenhouses and enjoying the benefits.

    Autoflower seeds in greenhouses

    Many greenhouse growers enjoy large harvests of over 100g (dried buds) from each autoflower plant. The protective environment of a greenhouse protects the autoflower plants from the worst of the weather and the extreme low temperatures which can occur especially in early spring and autumn.

    Autoflower seeds usually grow from seed to harvest in around 100 days in a greenhouse. Compared to feminized cannabis seeds that is a short life cycle. The short life cycle of an autoflower means it is extra important to optimise growing conditions and environment in order to maximise harvest quality and quantity.

    A greenhouse protects your plants from high winds, damaging rain and low temperatures. Insects and pests can be easier to deal with in a greenhouse and less of a nuisance. All these factors are reasons why greenhouses are a great asset for the cannabis grower.

    Feminised cannabis seeds and greenhouses

    Feminized seed varieties grow very well in greenhouses. Often, they will grow vegatively until they sense the shortening days, and will start to show first signs of bloom around August, depending on your variety. In the northern hemisphere feminized seeds are often grown from around April to October in a greenhouse.

    In a heated greenhouse the seeds can be germinated and planted around March/April, depending on your local weather conditions. This allows an earlier start than is usually possible outdoors. That’s because the greenhouse offers extra protection from the worst of the early season weather.

    As a result, a greenhouse allows you to grow larger plants which can start earlier and finish later than would be possible growing outdoors without a greenhouse. Many growers of photoperiod feminized seeds routinely harvest several hundred grams, or more, of dried buds from a single plant. Plants can easily reach 2-3 metres tall and just as wide. A greenhouse also protects your plants from the autumn/winter storms. This can allow the greenhouse grower to grow a broader range of later blooming cannabis seeds than is possible outdoors.

    Greenhouse cultivation of cannabis seeds. Using pots vs planting directly into the ground

    Greenhouse growers are split into two main groups; those that grow their cannabis plants in plant pots and those that grow them directly in the ground. Plant pots can be easily moved if they need to be, for example if visitors, extreme weather or other problems are present. But plant pots will need more frequent watering and occasional feeds. A large cannabis plant in a 10 litre container will need watering daily during very hot weather. That could be a problem if you are away and unable to visit your plants.

    On the other hand you may experience less issues with humidity, especially if your greenhouse floor is covered with paving slabs. Growing in containers also allows the grower more control over nutrient addition.

    Some greenhouse growers even feed their greenhouse cannabis with automatic systems (e.g. AutoPot, Blumat, dripper systems or similar). It’s possible to grow cannabis in soil, coco fibre or any other grow medium in a greenhouse.

    Plants that are rooted directly in the ground obviously can’t be moved, but will survive well even when you are away for a week or two. There is less need to worry about daily watering. If your greenhouse contains good quality moist soil then your cannabis plants will establish an extensive root network which will support a large plant with heavy yield potential. However, if the ground under the greenhouse contains poor quality soil then remove it and replace with good quality soil before growing plants in it. Serious greenhouse growers will dig in plenty of manure and compost at the end of each growing season to ensure optimized soil quality for the following years crop. One advantage of rooting your plant directly into the ground is that you can grow very large plants with unrestricted root space. It’s one way to get XXL harvests. Some greenhouse growers, when using the best cannabis seeds, find that a single plant can occupy the entire greenhouse and occasionally even run out of space. If this happens you can try low stress training to tie down the taller branches. In extreme situations, some growers have even had to remove some roof panels from their greenhouse if the plant grows uncontrollably. Plants which are rooted directly into the ground can be grown using automated feeding systems such as dripper systems etc.

    Greenhouse overheating. Protecting your plants from extreme summer heat

    One problem with greenhouse growing is that the temperatures can get very hot in sunny mid-summer weather. High temperatures make it difficult for the plant to grow. Leaves may wilt and the roots can find it difficult to provide sufficient water. This can be a serious problem, especially in a heatwave when temperatures inside the greenhouse can be in excess of 30ºC or even 40ºC. At these temperatures the cannabis plant struggles since conditions are so far from optimum. But the determined greenhouse grower can find ways around these challenges.

    Greenhouses can be fitted with windows which open in hot weather and close automatically when it cools down again. These allow the hot air to escape quickly. An open door in your greenhouse can allow a cooling breeze to flow through. Greenhouse doors made with panels of fine wire mesh keep insects out but allow air to flow through.

    Sophisticated greenhouse growers have watering systems in place to simplify and even automate water delivery. If the greenhouse is not in an entirely private location then it might benefit from a coat of white shading paint. This is sold in garden centres and used to protect greenhouses from overheating on the hottest summer days. For the cannabis grower this shading paint also stops people seeing what is inside your greenhouse, but green plastic plant mesh and tomato plants have also provided excellent cover for many generations of greenhouse growers.

    Anyone that has been in a greenhouse on an early spring day will note how quickly they warm up in sunshine. This allows growers to get their preferred cannabis seed varieties started earlier in the season than they could outdoors. This allows the growing season in a greenhouse to start earlier. Your greenhouse will therefore benefit from larger plants and subsequently superior harvests. Cold nights can be mitigated with the use of greenhouse heaters that are available to purchase at any garden centre.

    Just as with outdoor grown cannabis, the shift towards shorter days during the summer is a signal to the cannabis plant to start flowering and produce the desired female buds.

    How do I get rid of excessive greenhouse humidity?

    If you have ever seen your greenhouse windows dripping with condensation then you need to give some attention to reducing greenhouse humidity. Excess humidity creates an unhealthy growing environment for your plants and can encourage bud rot and mildew. Wet greenhouse glass panels will soak any leaves, branches or buds that press against the glass. If you want to ensure optimized plant health then consider some ways to make sure humidity doesn’t damage your plants.

    Ensuring air movement and regular air changes in your greenhouse is important. Some of the techniques used to keep your greenhouse cool will also reduce humidity. Having adjustable roof vents which can open to release humid air is a great help. Having a through-draft thanks to an open greenhouse door is also a good idea.

    Many greenhouse cannabis growers have fans in their greenhouse to move air around, and even to push air out of a door or open roof vent. This may mean fitting an outdoor, weather proof electricity connection to your greenhouse. But its a small price to pay for improved cannabis quality. A fan will also strengthen the stems of your cannabis plant by mimicking the effects of an outdoor breeze.

    Some people copy the large legal greenhouse growers in the USA and fit an extraction fan to pump humid stale air out of the greenhouse. This can be combined with a carbon filter to remove any cannabis aroma from the exhausted air.

    How large do cannabis plants get inside a greenhouse?

    If the greenhouse grower can get good soil for his plants and (most importantly of all) start with good cannabis seed genetics then the plants can grow into true monsters by the end of the grow season. The greenhouse grower can see cannabis plants reach sizes rarely seen indoors. Many greenhouse growers have grown single plants that have filled small greenhouses and produced several hundred grams of top quality weed per plant. Good quality cannabis seeds may cost more but they deliver far superior results in the long run.

    As previously mentioned, some greenhouses have windows that can be opened to let any monster plants grow out. But a safer option is to use cord to try to ‘tie down’ the plants if they do start growing massively. The photos above show what can happen when a prolific strain starts to turn into a large bush that wants to grow as high as a small tree. The plant simply becomes too tall for the greenhouse. The soil conditions, temperatures and good care resulted in a plant that was thriving as if in the jungle rather than a garden in northern Europe.

    Of course this type of extravagant growth rarely occurs when cheap cannabis seeds are grown in poor quality conditions with badly prepared soil. Growing a monster plant requires properly dug, well prepared nutritious soil at the start of the season. The pictures show large cannabis plants simply outgrowing the greenhouse, delivering heavy harvests for the grower. The Dutch Passion Shaman variety was bred specifically for outdoor/greenhouse conditions. Shaman combines some incredibly potent skunk/purple skunk parents with vigorous growth. Shaman eventually grew into a bush 3 metres tall and two meters wide, winning the Dutch Passion photo contest award in 2006. In this case the grower was forced to remove a pane of glass from the greenhouse as his resin soaked Shaman outgrew the tall greenhouse. The plant was too strong to be tied down, and security was not a problem on this particular grow so the grower went on to harvest an abundance of top quality greenhouse grown cannabis, despite the obvious size problems of the Shaman.

    Cannabis genetics and greenhouse growing

    When growing with good cannabis seeds in a greenhouse remember that some plants will grow as wide as they are tall especially if they have plenty of sun, good soil and ample root space. Remember too that a few seeds could provide a years worth of medication or recreational weed, so regard the cannabis seed as an investment and get a good variety. Cannabis seeds are one area of your life where you really don’t need to compromise. Look at the Dutch Passion website for some cannabis cup winning options. Proven varieties for greenhouse growing, especially at northern latitudes, includes Shaman, Durban Poison, Passion #1, Frisian Dew and Frisian Duck. These varieties have been used by numerous repeat growers over many years. They have passed stringent standards for potency, quality, pest/mold resistance and vigour. Growing these feminized seeds in a greenhouse will deliver excellent results.

    Early flowering using a ‘darkening system or extending your growing season

    Some growers equip their greenhouses with a ‘darkening’ system. Essentially this involves using dark blinds/curtains to create blackout conditions inside even when it is sunny outside. This can be used to simulate short summer days and ‘force’ the plants to start flowering and producing buds much sooner than normal. Although this involves extra expense it is one way of accelerating greenhouse weed production. The grower simply uses the blinds to reduce daily light exposure to 12 hours (or less) and the plants in the greenhouse respond by flowering.

    Greenhouses also have the benefit of allowing the grower to extend the end of the growing season. Cold sunny autumn days on the outside become warm and comfortable in a greenhouse and allow plants to ripen properly. Pests are normally easy to control in a greenhouse, and so long as the greenhouse is secure it is a great and simple way of growing.

    Many also grow cannabis seeds in polytunnels these days, the benefits of the poly tunnels being much the same as greenhouses. Polytunnels protect against the worst of the elements, keeping the plants safe and giving a long growing season. Polytunnels come in a wide range of sizes and they also offer privacy to the grower.

    Greenhouse growing of cannabis has lower ongoing costs compared to indoor growing, where large amounts of cash are spent on grow lights and ongoing electricity use. By contrast, growing cannabis in a greenhouse only requires a seed and some substrate to grow in. The sun provides free energy for your plants to grow.

    Greenhouse grown cannabis versus outdoor cannabis

    Many outdoor cannabis growers eventually upgrade to greenhouse growing. The greenhouse allows more potent crops, higher THC levels and a better terpene profile due to the protection offered by a greenhouse. Whether you are growing with a large commercial budget, or a small greenhouse with just one or two plants, the quality improvements are always important and appreciated. Because greenhouse grown cannabis plants grow in a more sheltered environment the plants are healthier, enjoying more optimized conditions. The plants can grow without damage from extreme cold, storm/hail damage and wind damage. Pests and disease are easy to prevent and deal with in a greenhouse. A greenhouse protects your plants from the worst of the weather, hail and torrential rain. Greenhouses protect your plants from cold weather, creating a warmer environment where your buds can ripen and mature under conditions which are often far superior to outdoor weather.

    Growing cannabis seeds in a greenhouse with artificial lighting

    Even in warm climates, many greenhouse growers supplement the natural light with additional light on cloudy days. These days LED grow lights can be used to provide additional illumination which can be automatically switched on when ambient daylight (PPFD) levels drop too low. Growers in cool climates, such as Scandinavia may prefer to use supplemental HPS lighting which offers both light and heat to the plants. Supplemental lights also allow you to extend the natural sunlight hours. This would allow you to grow autoflower seeds in a greenhouse and have 18-20 hours of daily light. Artificial light would be used to give the autoflower plants their preferred 20 hours of daily light with optimized yields and quality.

    The experienced grower can use the benefits of a greenhouse to grow larger plants, with improved quality and a longer life cycle. Plants can be started earlier and harvested later thanks to the extra protection offered by the greenhouse. During the cultivation process the conditions inside a greenhouse are better than those outside, promoting improved plant health, superior yields and better potency. Outdoor grown plants, without these benefits, usually offer lower yields and quality.

    Where to locate your greenhouse?

    If you get a greenhouse it pays to think carefully about the location. When it comes to security, always think about a location which makes it difficult for neighbours or the public to see/smell your crop. Also consider your local climate. If you are living in a cool climate it pays to locate the greenhouse where it will receive maximum sunlight for as much of the day as possible. If you live in a hot, desert climate you may want to consider locating the greenhouse under some trees which will shade the greenhouse during the hottest hours of the day in mid-summer. Mediterranean greenhouse growers may wish to place their greenhouse in a cooler, northern part of the garden where some shade may be present. Remember that when temperatures reach 40-45ºC the temperatures become damaging.

    Many greenhouse growers also arrange a hosepipe/water connection near their greenhouse. This simplifies the process of getting water to your plants. The last thing you need on a hot day is numerous long walks from your house to the greenhouse with a watering can.

    Greenhouse options for cannabis growers

    Greenhouses are available in a wide range of sizes and budgets. The lowest cost ones use a flexible transparent plastic mesh sheet which fits over a small plastic/metal pole frame. These can cost as little as €20 but can only fit a single plant inside. Some greenhouses are designed to be leant against an outside wall of the house. Heat from the house helps keep the greenhouse warm. Greenhouses are also available for people that live in an apartment and have a small balcony. Polycarbonate greenhouses use toughened ‘unbreakable’ transparent plastic panels instead of glass, these are useful if you are worried about safety or have small children. Whatever your budget and space, somewhere there is a greenhouse for you.

    Growing cannabis in a greenhouse. Easy and effective cannabis growing

    Growing cannabis in a greenhouse is a simple and cost effective way to be self sufficient in your cannabis needs. Greenhouse growing seems to be a rapidly expanding pastime amongst cannabis growers of all backgrounds in a wide range of countries.

    The more professional greenhouse grower will take care to introduce new, good quality soil/fertilizer each year and keep the greenhouse clean and tidy to minimise potential for pests and disease. Some greenhouse growers use strategically placed fencing and shrubs to make the greenhouse inaccessible to unwanted visitors and invisible to prying eyes. Greenhouses are cheap to buy. You can buy small low cost plastic ones for not much more than a hundred euros. Even cheaper ones are available with plastic covers. They are available everywhere and come in any shape/size required for all budgets. Some of the modern polycarbonate greenhouses are also opaque giving instant privacy and have lockable doors. What more could you need in your back garden? Remember that poor quality cannabis seeds can’t produce connoisseur quality cannabis, no matter how well you grow them. Invest in the best cannabis seeds you can get from a company with a proven reputation, and enjoying growing your own cannabis in a greenhouse.

    Thanks for the wisdom Dutch Passion, trying to prevail over the bad weather now in UK with some of your Frisian Dew. Closed up my greenhouse letting a good air supply breeze through some openings and one hole at the top for rain water to drip down. Wish me luck !

    We always hope for one of those late summer periods during the end of flowering, but we’re not always that lucky.
    But Frisian Dew should be able to handle some harsh conditions. So we hope you still end up with some great results! Good luck!

    Nice info!! I clear my doubt here. Keep sharing such info with guys. And also get more information about cannabis here, https://420expertadviser.com/grow-lights/mars-hydro-600w-review/

    Hi there Dutch passion, what is the best feed to put into your plant? Cherrs

    We advice biotabs for your plants, super easy organic nutrients which will make your babies happy!

    Hi, for a reason I have to move my indoor Plants almost 2 weeks at the end of the flowering period (12h ) outside where they get 11 hours direct sunlight..is it safe? are they gonna go back on vegetative grow again?
    Thanks for your advice

    This will surely bring some stress to your plants. When you move them outside do they get more than 12 hours of sunlight (not direct but in total)?

    Because if they go to an environment where they will have longer days they will go in to vegetative state again and you do not want this if your plant is finishing up flowering.

    Greetings,

    I am new at this. My plant has reached the top of my outdoor greenhouse. It is still in veg. stage Would it stress the plant if I remove the greenhouse? I has two doors that are open, so the plant has been getting a lot of direct sunlight.

    Hey,
    If the temperatures are not too low outside without a greenhouse this should be no problem and should not give a lot of stress to your plant.

    Hi.
    How many plants autoflowering per square
    meter I can put in greenhouse ?

    We advice around 4 autoflowers per square meters so they have enough room to grow big

    Greetings,
    Dutch Joe

    help ! I am at week 12 of auto flowers in a GH – but I think the grow has stalled ? super early signs of buds for the last 3 weeks but then nothing ? Started in June. Super bushy and good looking but no bud growth ? Any ideas ? should I start with some bloom nutes ?

    After 12 weeks you should definately have some bud production. If you want you can send us over some pictures so we can assist you better. Please send them to [email protected] with some information about your grow.

    Greetings,

    My plants are pushed up against the glass after two prunes will this effect the plants when they flower?

    If the buds are against the glass you have a high chance of bud rot because there is not enough air flow through the buds.

    Greetings,

    Will my plants still ripen in a opaque green house. Do I need a light in there. They are about 2 weeks from Harvest. But, we are getting down to 12 to 22 degrees Fahrenheit at night

    If you could give them some supplemental lighting that would be great. Your plants will have a hard time with these temperatures and with some extra light you can make it a successful harvest

    Is it possible to grow cannibis in a green house using a tinted plastic material or polycarbonate that isn’t crystal clear?

    It should be possible, but sunlight is very important for your plants. Sufficient light penetration should be possible with your plastic material. Do you know if other plants grow under this material?

    Greetings,

    Dutch Passion

    I have just received my californian orange seeds thankyou for your fast delivery I have ordered a plastic greenhouse and will be using pots do I germinate them inside my house first ? My garden gets very hot with sun from 9am to 7pm in summer

    It is indeed best to germinate them in your house because there the seeds will have a stable environment and temperature.

    In the first stage after the seedlings germinate you should be careful with direct sunlight because it can damage them.

    Hello, i have Auto Think Different in greenhouse in pot, but i dont know if direct sunlight avaible if better to stay in greenhouse or take pot to direct sunlight as much possible sometimes we have there also 30C, what do you think?Im from Czech Republic.thx for answer and sorry for bad english.

    If your pots are mobile, I advice you to move them out of the Greenhouse and in to the sunlight when you have extremely hot temperatures.
    If the temperature is around 20/25 degrees Celsius you can leave them in your greenhouse as long as you ventilate enough

    Greetings,

    Hello friends I live in a country where the use of marijuana is against the law. I intend to plant a greenhouse. Thank you for teaching me zero to one hundred planting jobs.

    I have started plants in a tent 18/6 lighting in Feb have taken out of Tent and put on dressing table before putting them in greenhouse, will they survive?

    To give a good answer we would need some extra information like the conditions that you have for your plant on the dressing table. Could you please send us an email at [email protected] with some explanation and perhaps some pictures? Than we can help you from there.

    At what stage should plants be moved during the day time from window sill to either greenhouse or garden? (In southern England where it is pretty warm now). I have the option of both garden or greenhouse

    Around 2 weeks after your seedlings have come out of the ground you can put them outside. Be careful in the beginning with too much direct sunlight, the seedlings cannot handle too much in the beginning. At the very start you can also take them inside at nighttime to protect them even more.

    Should I use shade cloth over my greenhouse in the hot summer days?

    Ventilation is really important in a hot greenhouse, if it really gets too hot you can use a shade cloth as well

    How to Grow Cannabis From Seed In 10 Easy Steps

    Whether it’s to control budget or because it’s hard to acquire clones, many are interested in learning how to grow cannabis from seed. Growing marijuana has never been easier or more accessible. Our guide to growing cannabis takes you from the planning stages to the final stages of your harvest. If you’re ready to start growing your favorite strain, keep reading.

    Step 1: Sourcing and Germinating Seeds

    If you can’t or don’t want to grow from clones, seeds are a great (and some may say better) alternative. Finding high-quality seeds is easier said than done. Dispensaries in states with medical or adult-use cannabis may carry cannabis seeds. In states without cannabis laws, finding seeds is strictly limited to online cannabis seed banks.

    Do your research on the many available seed banks that ship to the U.S. While many say they ship worldwide, they may exclude the U.S. in the fine print. Seed banks differ in seed selection. They also offer a variety of payment methods and discreet shipping. Some of the most popular seed bank sites include Attitude Seed Bank, True North Seed Bank, Amsterdam Marijuana Seeds, and Seedsman.

    Cannabis seeds require germination to jumpstart the growing process. The simplest way to achieve this is through the paper towel method. During this process, the germ in the seed breaks through the outer shell forming a root, also known as a taproot. Germination can take a day or up to a week. Germinated seeds can be placed in the growing medium.

    Step 2: Location and Light

    Cannabis can be grown indoors or out. However, most towns that allow for home cultivation require gardens to be secured and away from public view. Regardless of where you choose to grow, your space must have the right amount of light and space to grow.

    If you’re growing outdoors, consider any large trees that may cast a shadow or shrubs and bushes that can limit its space. North American growers should plant their garden in a space that faces the South to increase the amount of light it gets.

    Growing indoors? Consider the height of your space and garden. Don’t forget about including the hanging lamp height in your calculations. Grow lights need to be a certain distance away from lights to prevent burns and avoid stretching if the light is too weak.

    Indoor growers can grow in basements, garages, rooms, and even closets. Many growers start off with a grow tent, which provides a contained space for cannabis gardens. Many tent options come with all the necessary pots, lighting, filters, and fans needed to start growing from seed.

    Once you’ve chosen your preferred space to grow your garden, it’s time to consider lighting, an integral part of the process. Most growers choose metal halide (MH) lamps during the vegetative stage. They switch over to high-pressure sodium (HPS) bulbs during the flowering stage.

    Others may stick to their fluorescent and LED options. These can provide the right level of supplementary lighting for HID lamps. If you’ll be depending on LED lamps for your garden, make sure they have a full spectrum of white light. Full-spectrum LEDs are a bit more expensive than conventional HID lights, but they can save you money on energy bills. 250 to 400-watt HID lights can work for small gardens.

    Step 3: Medium and Container

    The medium of your plant refers to the base structure of your plant’s roots. A container keeps your medium, nutrients, and water contained when needed. Outdoor growers can use dirt, topsoil, compost, and other soil amendments to create a thriving microbiome needed to feed the plant’s roots.

    Indoors growers, on the other hand, are increasingly preferring soil-less growing methods. Mediums made from peat, sphagnum, and coco act like soil. They hold the moisture and air needed to absorb the necessary nutrients.

    Many smart pot options have holes around the sides and bottom of the container to improve water drainage. These breathable pots allow roots to get oxygen during the dark cycle. The pots prevent water build-up, which can lead to root rot and mold.

    Step 4: Nutrients

    Choosing the right nutrients is important for the best growth possible. Cannabis plants require certain nutrients to grow its roots, foliage, and buds. Nutrient solutions usually include an N-P-K ratio (nitrogen, phosphorus, and potassium). Nutrient solutions come in grow and bloom formulas for vegetative and flowering stages, respectively. Grow formulas have higher ratios of nitrogen compared to bloom formulas due to their differing needs.

    Start off by reading your nutrient solution’s instructions and create a diluted solution at ½ to …” the recommended dosage. Starting off with a lower-than-recommended dose ensures you don’t overfeed and ruin your crop. If within a week or 10 days you don’t see any signs of nutritional deficiencies, you can increase the dosage to the listed levels on the packaging. If however, your plant looks healthy, you can continue your feeding levels.

    Ideally, you want to use organic fertilizers to avoid salt build-ups in the medium. Organic and veganic nutrients are pricier than synthetic fertilizers, but they produce a far better product. Organic nutrients are helpful to bring out the cannabinoid and terpenes from your strain.

    Some outdoor growers choose to feed their gardens through a composted medium that has many of the minerals needed for the plant’s growth. Others use time-release pellets that contain nutrients that are slowly released into the medium.

    Step 5: Vegetative Stage

    A plant’s vegetative stage is the first (some might say most important) part of the growth process. Much of the plant’s size and yield are produced during this time. Some may say that longer vegetative periods can lead to bigger yields. Vegetative periods can last between a couple of weeks to a couple of months.

    Plants will remain in a vegetative stage when the light-dark cycle has more light than dark hours. Indoor growers set light timers to provide their plants with a minimum of 18 hours of light per day during this stage. During its dark cycle, the roots develop, so every hour of light and darkness matters.

    Many growers use MH bulbs during this stage. MH bulbs have blue wavelengths, which are necessary to keep your plants from growing tall and wild. Indoor growers may prefer this set-up to keep their plants short and bushy. MH bulbs can produce plants with short internodal lengths (the distance between the main stem and the branches).

    During this stage, you can employ different training and pruning techniques to maximize growth and yields. For instance, topping a plant involves removing the top shoot of the main stalk near the end of the vegetative stage. When cut, the plant produces additional shoots under the shoot’s cut, where buds can form during the flowering stage.
