Once you have the best pot or cup for your germinated seed, fill it with soil. After planting is done, the root system should always grow downward as the plant gets bigger. Therefore, you do not want to put in too little. The roots still need enough space to absorb nutrients.
Once you have everything you need, you can begin the process of planting your weed seeds.
Step 1 — Fill a Pot or Cup With Potting Soil
Not to mention, hard seeds may need up to a week to begin sprouting due to a thicker coating. If they have not germinated after two weeks, then they are likely a dud.
Weed seeds can grow indoors or outside, but growers need to pay attention to the time of year before planting outdoors. Cold temperatures can kill a cannabis plant, so you will need to place it outside as soon as winter ends. The recommended period is between April and mid-May. Seedlings require the entire growth cycle before temperatures drop again.
The best choice of soil for marijuana seeds is a light mix. The light mix does not have a high concentration of nutrients, which can be detrimental to a seedling’s health. Young plants do not need as many nutrients as mature ones.
Cannabis used for hemp production has been selected for other traits, including a low THC content, so as to comply with the 2018 Farm Bill. Consequently, many varieties of hemp produce significant quantities of CBD.
As mentioned above, you can skip the processing of sexing weed plants by growing with feminized seeds or clones.
Go easy on nutrients
Autoflowers can be started in early spring and will flower during the longest days of summer, taking advantage of high quality light to get bigger yields. Or, if you get a late start in the growing season, you can start autoflowers in May or June and harvest in the fall.
But if the seed you found looks decent, you might as well germinate it and see what sprouts.
A couple big drawbacks, though: Autoflower strains are known for being less potent. Also, because they are small in stature, they usually don’t produce big yields.
After 3–5 days, the seeds will start to open, and you should see tiny white tips appear. Once these roots reach 2–3mm in length, use extreme care to transfer them from the water to pre-prepared soil pots.
Your growing pots will need to be placed in a damp climate that is within the temperature range listed under our golden rules. After 4–10 days, you should see a young seedling sprout, while the roots will have begun to develop underneath the soil. The entire plant and its soil can now be transferred to a larger pot, where normal growing routines should start.
CHOOSING YOUR GERMINATION METHOD
Three fundamental principles will trigger that first small taproot to appear: warmth, moisture, and darkness. With the promise of moisture, a single root will take shape before slowly developing into the cannabis plant we know and love. In the right conditions, seeds will begin to develop within 12–36 hours of moisture being introduced to them.
There is, of course, a far simpler way to germinate seeds. Ideal for beginners, the feminized starter kit by Royal Queen Seeds has everything you need to kick-start your next cannabis project.
Timescales can vary, as it all depends on how ideal your germination environment is (see the golden rules above). Even the worst grower could make a seed germinate, but it may take a few weeks and, of course, increases the risk of a weaker plant.
