Growing cannabis is a lot like growing anything else. And as you would with most seed germinating, just follow the spring equinox…for the most part. The equinox falls in March, and while that might mean outdoor germination time in Arizona or California, Colorado is still liable to have snow through April and even May.

Ask a Stoner: When Should I Plant Seeds Outdoors?
Dear Kendal: Growing cannabis is a lot like growing anything else. Give it space, light, water, occasional protection from bad weather and maybe some nutrients, and it takes care of itself. And as you would with most seed germinating, just follow the spring equinox. for the most part. This year, the equinox falls on March 20, and while that might mean outdoor germination time in Arizona or California, Colorado is still liable to have snow through April and even May.
Freezing temperatures can kill seeds, so the best bet is to germinate them inside until the late snow passes.
Such cold temperatures can kill seeds, so the best bet is to germinate them inside until the late snow passes. If you’re only growing a few plants, this can be done in front of a sun-facing window. If you want to grow a lot, though, you’ll probably need to buy a growing light. Then transplant those baby weed plants outside before the summer solstice on June 20 (start watching weather forecasts after Mother’s Day). And go with a strain that has a short flowering time — because Colorado’s unpredictable snow usually returns in October.

When To Plant Marijuana Seeds Outdoors?
You’re not the only one wondering when to plant Marijuana seeds outdoors. Although it is a question that doesn’t have only one answer. Depending on what part of the world you live, the ideal conditions to plant marijuana seeds outdoors would be in the spring, between March and May (in the northern hemisphere). Ideally, during this time, your marijuana seeds should already be germinated and you can even plant marijuana seedlings that are a few weeks old outdoors. As we have mentioned in our other guides, to plant marijuana seeds outdoors is a numbers game. The more marijuana seeds you plant outdoors (if you don’t have the experience) the better your germination rates and eventual harvest will be. For Northern hemisphere climate conditions we don’t recommend to plant marijuana seeds outdoors, rather germinate and start growing the marijuana plant indoors until the weather conditions are ideal to take the marijuana plant outdoors.
When to plant marijuana seeds outdoors depends on the weather where you live
If you live in a place that has a constant good weather then the season isn’t very important to take into consideration for you to plant marijuana seeds outdoors. In places with less abundant sunshine, the season would last roughly from March to August or September depending if it’s an Indica or a Sativa marijuana plant. In other regions such as equatorial or coastal regions, the issue of when to plant marijuana seeds outdoors is non-existent since the constant warmth and humidity will germinate the marijuana seeds outdoors without any worries of the conditions being too harsh for the seedlings, or not enough humidity and warmth for the marijuana seed.

The Outdoor Grow Season: Cannabis Gardening
No matter how fancy and high tech grow rooms or tents may be, most growers agree that nothing beats weed raised on the pure, raw power of nature itself. On top of that, cannabis as a species has evolved out in the open for millions of years. Obviously, every last shred of cannabis genetics is meant to thrive in its original habitat, which makes the case for growing weed outdoors perfectly clear. Less sun in the season? Choose an Autoflowering strain. Perfect climate? Feminized is the right choice. With prime genetics like Amsterdam Genetics cannabis seeds, anyone can prepare for a great kickoff to the outdoor grow season!
We’re all aching to catch a bit of a tan and soak up some much-needed vitamin D under the prevailing lockdown conditions. Gardening is a great way to do just that – including cannabis gardening, obviously. As the spring equinox approaches, it’s time to pick that perfect strain and start preparing to germinate and grow some plants!
When Does The Outdoor Cannabis Grow Season Start?
Several factors determine the perfect timing for the start of the outdoor grow season. Geographic location matters, as spring doesn’t bring warmth and sunlight to all regions simultaneously, or in equal measure. Still, from a global perspective, the spring equinox is an important point on any grower’s calendar. The spring equinox officially marks the first day of spring; in the Northern Hemisphere at least. Every year, around March 20, the Sun crosses the equator parallel, promising more hours of daylight and warmer weather to come. For the southern half of the planet, the March equinox hails the start of autumn, as the annual seasonal cycle proceeds in the exact opposite direction.
The Outdoor Grow Season, Step By Step
Let’s see how you can best prepare for the oncoming grow season. If you know what to do and when to do it for perfect timing, you can spend all spring and summer dreaming of that glorious harvest time as you watch your grass grow. Here’s our month-by-month guide to the ultimate outdoor grow season!
Late February Through March: Planning For Planting
Picking An Outdoor Grow Location
By late February, as the first brave snowdrops and crocuses burst from the soil, it’s time to stock up on seeds and pick the cannabis genetics that best match your taste and grow goals. This is the time for planning ahead – don’t forget that the time for planting is drawing closer every day now…
It all starts with great seeds…
Try to decide on the best spot to plant or pot cannabis plants after germination. Our outdoor grow locations blog helps weigh all the relevant factors and pick the prime weed growing spot in any garden. Aim for the optimal combination of sunlight, shelter from bad weather, and a stealthy spot to avoid unwanted detection. Growers who have found found that sweet weed spot are good to go. Start by loosening up the soil and add some organic fertilizer to optimize your natural open-air grow medium. Read up on the best soil for growing weed here.
Find The Perfect Match In Outdoor Cannabis Seeds
Picking the right cannabis seeds is possibly the most important step on the road to the harvest of your dreams. There are many things to consider here. Are you looking for specific genetics, such as sativa seeds or indica-dominant strains? Are you growing for specific effects, or a favourite flavour? Perhaps you want to grow medicinal cannabis for stress relief, to combat depression, or to treat (chronic) pain issues? You’ll find all of this and more among the thirty-plus world-class strains in our online seeds catalogue.
Growing Weed In Warmer And Cooler Areas
In the northern parts of the Northern Hemisphere, including Canada, US states up north and Northern Europe, summers tend to be rainier, cooler, and shorter than those in more southern regions. That is why southern growers can start germinating and pregrowing their seeds in March, planting them once the April sunshine comes. In northern areas, May is the best month to plant germinated seedlings outside. Growers could can decide to pregrow seedlings indoors as early as late February to give their weed a head start for when spring arrives.
The start of the outdoor season varies between regions.
Feminized, Autoflower, Or Regular Seeds?
Then there’s the choice between photoperiod seeds or autoflower strains that start flowering automatically. Regular seeds can grow into male or female plants, giving you extra options and flexibility, but feminized seeds maximize your grow efficiency by yielding 99% feminine plants with harvestable flower buds. That’s a lot of choices to make – better start picking the best feminized, regular, or autoflower seeds to order. Give the delivery guy or girl enough time to ship them over, because once you see the first signs of spring, April is just around the corner!
April: Germination And Pregrow Time
Come April, even northern outdoor growers can start growing seeds. As the days lengthen and the sun gains strength, this is a good moment to germinate your seeds. If you still haven’t decided, order your cannabis seeds now to make sure they arrive in time. Germination, as this blog explains, is the moment when a tiny weed seedling emerges from its protective seed shell. The first root and leaves peep out, ready for their first drink of water and touch of sunshine.
Germination: a special moment both indoors and outdoors.
Growers working in Mediterranean climates can start planting seedlings and pregrown cannabis plants outside in April. For the northern parts of the US, Canada, and Northern Europe, this is the time to start germinating the seeds you bought. Once they pop, put them in small flower pots in the window sill where they get lots of early sun. Another option is to set seedlings off in a (pregrow) tent under artificial lighting. That way, your young plants are stronger once you take them outside in May. Having a little greenhouse available makes it safer to plant outdoors in late April, but even then, the option to bring fragile sprouts back inside if a late frost spell hits is a safe bet.
May: Time To Plant Your Outdoor Cannabis Grow!
Yay – you’ve made it to May! This is when spring peaks all over the northern half of the world, ready to tip over into summer warmth. June and July are the most prolific growing months of the year, so planting young plants in May lets them make the most of the summer throughout the vegetative stage of their life cycle. By now, your pregrow should be past its infancy, with the first real branches and characteristic weed plant leaves starting to shoot upwards to the heavens. If you haven’t germinated your seeds yet, you’ll want to do so now, preferably planting them outside as soon as they pop without further delay.
Useful Tips For Your Outdoor Grow Season
If you’re not sure which seeds to pick for this year’s outdoor grow season, we have a few suggestions to help you on your way.
Outdoor Indicas & Indica Dominant Strains
Our seeds catalogue indicates the average flowering times of every strain we have. As a rule of thumb, cannabis with more indica-dominant genetics tends to flower faster. They evolved in mountainous Asian regions where they had to flower quickly before the cold weather returned. That makes them great for northern climes and their shorter summers. Added benefit: indica strains tend to grow short and bushy, making them easier to hide and manage in gardens with limited space. Pineapple Kush is a good example of a heavily indica-leaning strain, as are Strawberry Glue and our sweet-tasting Chocolato. Broadly speaking, these same considerations also apply to hybrids with dominant indica genetics.
Strawberry Glue is a nice indica-heavy outdoor strain.
Outdoor Sativas & Sativa Dominant Strains
Sativa genetics evolved in warmer equatorial regions, enabling them to enjoy long, hot summers and loads of sunshine. That is why sativa strains tend to have longer flowering times than indicas, making them more suited for sunny, southern areas closer to the Mediterranean, or the southern coastal areas of the US. If you are growing weed up north and you’re after typical sativa highs and their cerebral, energizing head buzz effect, try finding a strain with a nice balance of indica and sativa genetics. Cannabis seeds such as White Choco, Tangerine G13, or Choco Cheesecake are good examples. Sativa genetics tend towards tall plant growth, which can make stealthy growing tricky. On the other hand, sativa strains usually feature open, airy bud structure. That can help prevent mold damage from culprits like bud rot or mildew. Indicas tend to have more compact buds that can prove risky during the cool, damp conditions associated with harvest time up north.

Autoflowers Make The Most Of The Cannabis Grow Season
Autoflower strains are a brand apart when it comes to outdoor growing. These plants carry cannabis ruderalis genetics in the mix, which enables them to start flowering at their own preferred time rather than waiting for the days to grow shorter around midsummer. If you play your cards right, planting autoflower strains early in the season (preferably pregrown indoors for a solid start outside), you could squeeze in two or even three grows into a single cannabis grow season. Depending on your location and the weather conditions, you could take autoflower plants outside in April (if there’s no chance of late frost).
Choco Kush Autoflower in full bloom.
Pick an autoflower with a very short flowering and grow phases and you should be able to harvest in late June or July. That gives you enough time to get another grow going before it gets too cold – even if you don’t have much space. Do keep in mind, though, that the speed at which the automated beauties develop limits your options to guide them or correct your mistakes. Try to pick a robust, rugged strain with high resistance to pests and fungi. Milkshake Kush Auto and the hugely popular White Choco Autoflower strain are our prime suggestions for your automated outdoor grows. Autoflowers are usually vulnerable to overfeeding, so go easy on the nutrients and keep them close for daily inspection.
