How and When to Plant Marijuana
Many people aren’t really sure when to plant their crop. When’s the perfect time of year to germinate your seeds so that everything runs as smoothly as possible? Well, this depends on what medium you’re growing in, the accessories and things you have at your disposal etc. You can grow the perfect crop at any time of year depending on how you’re doing it and what you have. Today we’re going to show you techniques so that you can get the absolute most out of your plants regardless of what time of year it is.
How and When to Plant Marijuana Outdoors
If you’re looking for normal marijuana plants (2m 500mg +/-)
When spring arrives we all know that it’s time to start germinating your marijuana seeds for your outdoor crop. It’s the most important crop of the year as it’s where you can get the most production of the entire year. Old school growers like to plant their seeds for the first full moon of March.
The reasoning behind this is so that while your seeds are germinating they’ll also have light at night time and they won’t stretch up too much in their first days of life. Sometimes it’s a bit too cold at that time though, and of course you can’t plant at the same time everywhere, we’re talking from a Spaniard’s point of view here. If you live somewhere with a very cold climate your plants will take much longer to grow and they’ll get stressed out from cold or wind, which will create weaker plants that are more susceptible to infestations and fungi.
The best thing to do in this case is to wait another month or two; a germinated seed in a decent climate from April onwards will actually be bigger and better grown than one planted in March in the same place.
Taking care of plants for such a long time is quite a lot of work for the grower, you need to keep an eye on infestations, fungi, nutrition, transplants, pruning, tutoring… The whole process takes about six months of constant work. If you’re looking for a decent product and yield, you’ll need:
- Fertilizers for growth and flowering. You can use your preferred fertilizers, organic hummus, guano for growth, a booster for the flowers and a base fertilizer for flowering should be enough to get a productive and flavorful plant. If you use chemicals then you’ll need a complete range from a specific brand that’ll give your plants the minerals they need to make the most out of the flowers. Of course, chemical products reduce flavor but increase yield, whereas natural products intensify the flavor but make for a lower yield.
- Insecticides for insects like white flies, mites or thrips. Preventive insecticides are recommended to avoid any scares.
- An anti-fungi product that works well against oidium. Propolix or other chemical products work well, but you’ll need to use it from the start.
- Bacillus Thuringiensis; this is used for caterpillars and other worms. Use it as soon as flowering begins, which is when these pests start to appear. Around May/june.
- Stakes or wires to keep the branches up during the flowering period.
If you’re looking for small plants (1m 250g +/-)
If you’re looking for some small to medium sized plants, both compact and strong, then you’ll need to wait till around the middle of March to germinate your seeds. Your plants will have about a month to grow before the light period changes, and they’ll grow with more sun than other plants, making for strong and compact specimens. So, when they begin to flower they will be more compact, around 1m tall. You’ll need the same products as for large plants, as well as patience although less due to the fact that they take a lot less time, around three and a half months. This style is much easier for beginner growers, although you’ll still need to take care of them.
If you want gigantic plants (3m 1kg+)
To get these kinds of plants you’ll need to apply yourself to the job more than the other two types. You’ll need to grow plants with a decent size so that they can grow amazing 2m long branches in all directions with buds as thick as your fist that you’ll need to hold up with a SCRoG mesh so they don’t break.
If you’re looking to grow a plant of this size before June then you’ll need to grow it for at least six months so the plant has more surfaces to flower on, which should take another three months. You’ll get much better results if you plant straight into the ground rather than pots.
To be able to grow it for so long you’ll need to do so in a greenhouse. You’ll need to buy or make your own plastic greenhouse. In a greenhouse your plants can avoid the cold during the winter as well as receive enough light to grow properly. You’ll need to germinate your seeds in December. You should germinate them inside so that they don’t die off at the start and they can get a nice warm germination.
Then, you’ll need to make a hole around 50x50x50cm and fill it with new substrate so the plant has a decent medium to grow in. Once your plant has germinated and it’s a few centimeters tall you can officially move it to the greenhouse. You’ll need to install a light above the plant that should turn on for 10 minutes every four hours or twice a night so that it still grows during the winter. The light doesn’t have to be super powerful, the only reason we do this is to annoy the plant and keep it growing. Once the plant reaches around 40cm, you’ll need to start pruning it starting with the main calyx. Two or three weeks later, prune again on the higher branches, two weeks later another one… until after a couple of months you have a big ball of leaves full of mini-calyxes which will later grow into long branches.
More or less around February you’re going to need to place four stakes around your plant in a 1mx1m formation, with the plant right in the middle, and then place a SCRoG mesh over it to separate the branches as much as possible and as wide as possible. Once March arrives you’ll need to take the light away and let it get used to natural light and the growth period lighting (these dates are for Spain). Once you notice the good weather starting again, sometime near April, remove the greenhouse and let your plant breath fresh air. Your plant will be a meter tall, when everyone is is still germinating at this stage, which a whole lot of branches and prepared to grow for another three months. Once June/July arrives, your plant will be absolutely huge. Just before it flowers you can place another mesh so the branches can put up better with the weight of the buds. You’ll need to keep an eye out for infestations and fungi due to the size of the plant and how hard it can be to inspect all of it. It’ll need good nutrients due to how long it’s going to grow, and you’ll need to water it properly. You can get the entire years’ worth of gear in just one plant. Happy growing!
Soil Germination Method in 8 steps
Amongst the best ways to germinate cannabis seeds, this soil germination method is a low risk, easy method that explains how to germinate your seeds in soil. Germination can take 3-10 days, depending on environmental conditions and variety
Never use soil from your backyard! It can contain pests and moulds that will damage or destroy your seeds, seedlings or plants.
How to germinate seeds in soil
Read here which 8 steps you have to take for this soil germination method.
Step 1: Prepare your soil
Prepare your pots with clean fresh soil. It is often easy to use small pots for this, and transport them to a larger container later.
Step 2: Watering the soil
Make sure your soil is wet, but do not soak it. It needs to be damp but not soaked, otherwise you risk your seeds to rot. In most countries, normal tap water is clean enough to use. Do not add any additives to the water.
Step 3: Placing the seed inside the soil
Make a small dimple in the soil and place the seed 3-5mm deep inside the soil. Don’t bury your seed too deep! When you put your seed too deep inside the soil, it will struggle to reach the surface, and have a high risk of dying before it does.
Step 4: Cover the seed and press gently
Cover the seed with soil and press the soil gently.
Step 5: Cover the pots with kitchen foil
Cover your pot(s) with kitchen foil or microwave foil (with the small holes). The foil will act like a small greenhouse, keeping the inside of your pot warm and moist. Perfect for germination.
Step 6: Poke some holes
When you use normal kitchen foil, poke some holes through the foil. This will avoid the risk of overheating and let air flow true.
Place your setup in a room with stable temperature. 20-25 degrees is ideal. We often advice your living room
Step 7: Wait for germination
All you have to do now is wait. In our experience it often takes about 4-5 days for your seedlings to show. But to calculate for differences in conditions and seeds, we say 3-10 days is a safe estimate. As soon as your seedling has sprouted (first leaves reach the surface) you can remove the foil.
Step 8: Take care of your seedlings
All 5 seeds germinated in 4 days within 24 hours of each other. You can now place them under a grow light, behind your window or outside (during spring / summer of course).
WARNING! Do not place this germination setup outside in direct sunlight, especially during summer. Day and night temperatures vary too much and sunlight will cause the temperature inside your soil to rise to a point where your seed will be damaged or killed by the heat.

buongiorno dutch passion ho seguito il vostro tutorial e dopo 4 giorni la germinazione è avvenuta.una domanda vorrei fare,devo aspettare che si aprono i cotiledoni prima di rimuovere la pellicola o posso mettere il vas gia al sole anche se non sono aperti i cotiledoni. grazie e buona domenica
tutto ok germinazione perfeta.
When a seedling is in its first days its best to not place it in direct sunlight. This can be too much for a little seedling. When the seedling starts growing a little bit you can place it in direct sunlight
ok perfect I do this because I saw that it is the best method.I had put it in direct sunlight and it was dying, I managed to save it in time.I have one in germination and I will apply your advice.thank you very much Joe
Once the stem has come through the soil how long till you put it on a larger pot and up the tempreture
It depends a little bit on the pot size you started with.
Additionally, if you grow an autoflower its best to germinate them in the pot they will also flower in. They don’t like to be transplanted a lot.
If you grow feminised seeds than you can put them in a larger pot after 3/4 weeks.
Sweet thank you ,
Hi, Joe answering?? I did an error putting seeds in soil not enough wet and under lamp … I choose Orange punch feminized and autoflowering…Is a good choice for me ad a beginner or could you give me best options? (Medium-high THC and quantity of final result) I also need some good ideas about the soil to use and the power of led lamps (I’ve buyed 2x100watt multiple ranges led lamp for plant grown for about 60cm x 40cm for 4/6 seeds). I have to do another order and I’m trying to do all well. Waiting hopefully for your answer, my best regards, thanks. Heathcliff
Critical Orange Punch is a good strain to start your growing career. Please try to follow the germination steps from this blog and you should be fine Don’t start your light if the seeds have not germinated yet. For your soil I advice you to have a type of soil that has minimum nutrients because seedlings cannot handle too much nutrients, these should be added later :).

Hopefully all of you aspiring growers have been able to get your seeds so we can move to the next step: germination.
Take great care handling seed and seedling. Most flower and vegetable seeds are simply planted directly in the soil, but because of the value of cannabis seeds, germinating seeds prior to planting is encouraged. Growers can achieve a much higher survival rate by germinating in a non-soil medium and then transferring the seed to soil once the tap root has emerged from the seed.
Here is one of the simplest and most successful methods: Put a double layer of paper towels on a dinner plate, then thoroughly soak the towels with water and tilt the plate to drain off the excess. Place your seeds on top of the wet towels and cover with another double layer of soaked paper towels. Be sure excess water is drained off—you don’t want the seeds to be swimming.
Cover the plate with an upside-down plate or pot lid. A plastic bag or plastic wrap also works. Don’t make the seal tight—you want to leave some openings to allow air flow.
Keep the germinating seeds away from direct light. For best results, keep them at about 75 degrees Fahrenheit. A radiant heat source, like a heating pad, helps expedite the process. If you’re using a heating pad, be sure to keep the heat setting on low and place a folded hand towel between the heating pad and plate: Direct contact between the plate and heat source can cook your seeds.
Under the right conditions, seeds usually open in one to five days, so check them daily. Do not allow the towels to dry, and add water as needed to maintain moisture. Some seeds can take as long as 10 days to germinate, but if seeds have not opened within 10 days, they are not viable.
When the seeds open, the first thing to emerge is the root. Once the root sprouts it can grow quite fast.
When the root grows to a few millimeters in length, the seed is ready to be transferred to soil. Always take great care not to damage the tap root when handling. The best soil to use for a sprouting baby ganja plant is a “seed starter” or “seedling” mix. These are light neutral blends with very little fertilizer. Heavily fertilized soils will kill seedlings quickly, and cannabis seedlings prefer loose, aerated soil that their roots can easily penetrate. A bag of good starter soil is easily identifiable: When you pick it up, it should feel light and fluffy. Soils that are heavy and compact are not good for seedlings.
Now, on to potting (no pun intended). A healthy seedling will be ready for transplanting into larger container, with richer soil, in about a month. A 16- to 20-ounce container is ideal for a seedling’s first home (many growers use a Solo cup). The container must drain, so punch some holes if needed.
Fill your container with pre-moistened soil and create a hole about a half-inch deep for your seed. The tip of a pencil works well for making the right sized hole. The seed should be about a quarter-inch below the surface.
Place your germinated seed, root down, into the hole and cover lightly. Do not pack the soil on top of the seed; a light protective layer of soil is all that is needed.
Once they sprout in one to three days, new seedlings will need lots of light, and fluorescent grow light works best. Give your baby ganja plants 16 hours of light per day.
It’s very important to have a breeze on your plants immediately. A fan placed at the proper distance and speed should create a breeze just strong enough so your plant “dances,” but not so strong that it’s bent in one direction.
Without a breeze, indoor ganja plants won’t receive the stimulus needed to develop sturdy stems and branches, which the plant will need to bear the weight of big, sugary buds.
