Question: How To Grow Good Weed Indoors Step By Step

To accelerate germination, soak your seed in a small container with lukewarm water and place it in a dark and warm place (like a kitchen cabinet) for 12-24 hours, but no longer. By drenching the seed, it absorbs the water thoroughly, activating the germination process on a physical and chemical level.

Whats the best soil for growing weed indoors?

The best ingredients for good cannabis soil include: Coco coir peat: Also called coco fiber, this is made from coconut husks. Perlite: Light rocks that improve aeration and drainage. Earthworm castings: Worm poop may not be the most appealing ingredient, but a cannabis plant’s roots can’t get enough of it.

Can you plant weed seeds straight in soil?

Yes, you can. But. Once easy step before that will help alot. In a small jar put some water and soak the seed overnight, water down your soil before planting, then poke a small hole (I use a nail) about 1/2 inch into the soil, now take some tweezers and drop that seed in that hole.

What do I do after my seeds sprout indoors?

Check your seed trays daily for germination, mist with water if the soil surface has dried out, and wait for seeds to emerge from the soil. Once the seeds sprout, remove the humidity dome and place the trays under lights. Keep the lights within 2-inches of the tops of seedlings.

What nutrients do you need for growing weed?

The main macronutrients involved in plant nutrition are known by the acronym NPK, they are nitrogen (N), phosphorus (P), and potassium (K). They are necessary for Cannabis plants to grow strong, healthy, and to achieve a major final crop.

How long does it take for seeds to sprout indoors?

In most cases, seeds will germinate within three weeks (after that, try starting a new round of seeds). spot in your house (preferably a south-facing window). Continue to keep the mix moist, but not overly wet. Seedlings should be watered once a day or every other day, depending on how much sun and heat they get.

How do you germinate weed seeds in dirt?

Cannabis Seed Germination: Direct in Soil Method Step 1: Prepare your soil. Step 2: Watering the soil. Step 3: Placing the seed inside the soil. Step 4: Cover the seed and press gently. Step 5: Cover the pots with kitchen foil. Step 6: Poke some holes. Step 7: Wait for germination. Step 8: Take care of your seedlings.

How often should I water my coco seedlings?

The frequency of watering depends on the evaporation and the water supply in the COCO. A common rule is; one daily watering is sufficient during the first few weeks under normal circumstances; then increase up to 2 times a day; 2 hours after the lamps have been turned on and 2 hours before they are switched off again.

Do seeds need sunlight to germinate?

All seedlings require sunlight. Seedlings will become leggy and fragile and will not produce to their potential if they do not have sufficient light. Table 1. Soil temperature conditions for vegetable crop germination.

How often do I water seeds?

Yes, seeds normally need to be watered at least once per day to keep the soil moist, not permitting it to dry out. In especially warm climates (or depending on your soil or garden setup), you may need to water more than once per day. Check on your seeds or seedlings frequently to make sure they have plenty of water.

Is Miracle Grow fertilizer good for weed?

Don’t! MiracleGro is not recommended for use when growing marijuana. The main issue with MiracleGro is it provides one formula of nutrients used throughout a plant’s life cycle. Weed plants go through several different stages through their growing cycle, from seedling to full flowering.

What does weed need in flowering stage?

Nutrients for Cannabis plants in the flowering stage The main nutrients that the Cannabis plant needs to develop are Nitrogen (N), Phosphorus (P) and Potassium (K). When the plant starts to bloom, the concentrations of P and K must be increased progressively, while the N concentrations are lowered.

What fertilizer has phosphorus and potassium?

For example, winterizer fertilizers will have a high third number – high component of potassium. A common type of all-purpose fertilizer is referred to as 10-10-10. This is a balanced blend of equal portions of nitrogen, phosphorus and potassium.

Should you water seeds right after planting?

Many seed starters cover the container to keep soil moist until seeds germinate. Once seeds sprout, do not miss a watering. Unlike established plants, seedlings do not have an extensive root system they can rely on for vital moisture. At the same time, it is important not to overwater and let seedlings sit in water.

When should I start my seeds indoors?

Start your seeds indoors about 8 weeks prior to planting day. This will give enough time for solid strong growth before planting outside permanently. It gives us plenty of time to grow indoors, and then begin to harden them off on the warmer days on our back porch.

Should weed seeds sink or float?

Since viable cannabis seeds float on the surface of the water, they are able to retain the proper ratio of moisture and air. Seeds that do not float may be sterile or underdeveloped. Immature cannabis seeds appear green or sometimes white and as stated above they will sink to the bottom when you attempt to float them.

Can you germinate seeds in just water?

Why would seeds not germinate in water alone? Plain water usually doesn’t have enough of the nutrients needed for seeds to germinate. Also, there is nothing in the water for the roots to grasp onto as they develop.

How long should you leave weed seeds in water?

You shouldn’t leave seeds soaking in water for more than 32 hours. Otherwise, seeds that haven’t sprouted yet will drown. If the seeds haven’t germinated by the 32-hour mark, put them in a warm and moist place to complete the process.

How to Start Seeds Indoors

Coaxing new life out of a seed is one of the highlights of the year for gardeners, right up there with harvesting perfectly ripe vegetables (at least in my opinion). I’ll never tire of watching delicate seedlings break through the soil and stretch towards the light (hopefully not having to stretch too far!) and I love the feeling of productivity that starting seeds indoors gives me as winter seems to drag on and on. It’s like a little bit of the life and hope of spring inside my home.

Starting seeds indoors gives your vegetables, herbs, and flowers a head start so they can grow larger and have better (and longer) harvests or flowering periods. With a few basic supplies and a little patience, it’s easy and fun to start seeds indoors. As everyone knows, a little tending is good for the soul!

Seed-Starting Supplies

Seedling tray with cells, drip tray, and cover

Seed-starting soil mix

Fluorescent or LED grow lights

Spray bottle “mister” and watering can with rain nozzle

Face mask (optional) – we’re all pretty experienced with these nowadays!

Don’t have time for a lot of details? Don’t worry, I won’t take it personally. You can jump straight to the section How to Start Seeds Indoors in 4 Easy Steps (and come back to the details another time. I mean, they are pretty good details. Just saying).

Seedling Trays

You can start seeds in almost any small container as long as it allows drainage but the easiest and most efficient choice is a seedling tray with cells (compartments). When it’s time to transplant, it’s easy to slide the plant and soil out of the cell and into the garden or a larger pot. These plastic trays can be reused for several years. Just remember to clean them well before reusing them.

You will also need a drip tray to catch draining water and a clear cover, which is essential for keeping in moisture and heat while your seeds germinate.

Soil for Seeds

Seeds need sterile, lightweight, moisture-retaining soil that is also well-draining. I recommend E.B. Stone Organics Seed-Starter Mix. Before sowing, place the soil in a large bowl, sprinkle with water, and mix to moisten it evenly. This is when you might want to wear a face mask since the soil is very fine and dusty, and can irritate airways. You’ll also want to wipe down any nearby surfaces with a damp cloth when you’re done.


Light is essential! Sadly, our PNW winters don’t offer enough light to help a seedling grow big and strong (yes, even in a south-facing window. It’s all those clouds). You don’t want pale, gangly, weak seedlings, do you? I didn’t think so. So… you need lights.

You can use T12 or T8 fluorescents but T5 high output fluorescent lights or LED grow lights are more efficient. The nice thing about LED lights is that they offer the same strength of light until they burn out. With fluorescents, the strength can wane as they age, so it’s recommended to change them every 12 months, even if they haven’t completely burnt out. Get fancy with red/blue spectrums or, if you don’t want your home to look like a nightclub, stick to all-spectrum white, which will work just as well.

Position the lights about 2-3 inches over the seedlings and adjust them to keep them at this distance as the plants grow. A chain on hooks makes it easy to adjust the height of the lights. If your light source is fixed, you can just adjust the height of the trays. Turn the lights on after your seeds have germinated (the exception is lettuce, which needs light to germinate). Seedlings like 12-16 hours of light per day. A timer makes it easy; no remembering to turn the lights on and off.

Heat Mat

Imagine it: you’re cold, it’s dark, and it’s damp. Do you feel like waking up and expending energy? I certainly wouldn’t. Add a little heat to the mix, though, and… well, I still wouldn’t want to wake up but your seeds will. Many seeds will germinate only in warmer soil temperatures and a heat mat can help speed up germination and keep fungus from growing. You can remove the heat mat when your seeds have germinated.

Mister and Watering Can

A spray bottle/mister is perfect for keeping the soil damp but not soggy while you wait for your plants to germinate and also while the seedlings are tiny. Once they’ve grown a bit, you can begin to water with a watering can that has a rain nozzle so the water is gently dispersed and doesn’t flatten your seedlings or you can also water from the bottom if you use plastic cells. Just fill the solid tray underneath your containers with an inch or two of water, which will be absorbed by the soil, keeping the seedlings safe from floods.

I recommend filling a large watering can or bottle with tap water and letting it sit for a few hours to a day to warm to room temperature. Seedlings aren’t much for cold showers!

Plant Labels

I admit I’ve been known to skip labeling my seedlings, imagining that I would definitely remember which cell contained which precious seed. Yeah, right. The larger the variety of seeds you plant, the more you need to label them so you’ll know what is growing where. The plants may look distinctive when they’re mature but many seedlings look a lot alike when they’re just getting started.

I made flags with toothpicks, sticker labels, and markers, and used clear tape to cover them. While they still wouldn’t last long inside the tray when it’s covered, they work really well after the cover comes off (if I try to not drench them when watering). I also like colorful Rapiclip plastic plant tags, which can be transferred out to the garden with the seedlings and used year after year. Just write the name of the plant in a permanent marker. For either type of label, I tape them to the outside of the cover until the seeds germinate and the cover comes off; then I stick them into the soil.


Now for the best part: the seeds! Lots of vegetable, herb, and flower seeds can be started indoors and transplanted into the garden or into outdoor pots when the time is right. Here are a few options with their ideal sowing times.

It’s always advisable to check your seed packet for exact timing and to see whether it is recommended to sow that particular seed indoors or directly into the garden. Crops like lettuce, arugula, and spinach can be sown outside by early March. Beets, radishes, and carrots are generally sown directly outside rather than indoors because they dislike being transplanted.

Sow in January: arugula, lettuce, onions, scallions

Sow in February: arugula, broccoli, calendula, eggplant, kale, lettuce, onions, pansies, parsley, peas, peppers, snapdragons, spinach, tomatoes

Sow in March: bachelor’s buttons, broccoli, cauliflower, corn, cosmos, eggplant, marigolds, nasturtiums, pansies, parsley, peppers, tomatillos, tomatoes, Swiss chard, zinnias

Sow in April: basil, beans, bok choy, cucumbers, ground cherry, melons, pumpkins, squash (summer and winter), tomatillos, zinnias

Planning Your Business

If you’re planning to grow for personal use only, you can skip this section and continue on to Chapter 1 below.

Planning to grow marijuana as a business? Well, you’ve come to the right place!

As with any business, you should start by researching the market circumstances and legal considerations in the area you plan to operate. Your business will be very different depending on your goals: Do you want to grow medical marijuana or recreational? At what scale? And in what state?

What will your team and setup look like? How many people will be involved? How much is the investment for setting up the grow room? How much are the monthly costs for water, electricity and other supplies? Can you grow in your house or do you need a commercial area? How will you be distributing your weed buds?

If you are considering growing marijuana as a business – treat it like a business. Do your research beforehand. Identify your target customer and how you’re going to reach them. Research the balance of supply and demand in your market — your work will be much easier in a market that is supply constrained, so that may influence where you decide to set up your grow. What are the financial and legal risks and how can you manage these risks? Are you willing to take a legal risk or not? A business plan can help you structure your thoughts as well as forecast your cashflow.
