Dear Stoner: I want to throw some seeds in the ground in my backyard this year. Should I do it at the same time as my other plants and flowers, in April or May? Earlier? Later?

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.

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.

If you’re growing outdoors in a climate that’s hot and sunny, heat stress could be a problem. Ensure that your plants have some access to shade, especially around midday. Put up some shading or choose a spot with some natural shade to protect your plants from the heat.
Seedlings are very sensitive and do not take kindly to growing mistakes like improper humidity and moisture levels. Both could spell the premature end for your seedlings.
As an alternative to plastic pots, you can also use fabric pots (smart pots) or air pots. If you want to learn more about the different pots used to grow cannabis, check our article on the subject.
10. HARVESTING TOO EARLY OR TOO LATE
Monitoring pH is important since cannabis can only uptake nutrients within a relatively small window. If the pH level is too low or too high, your plants will get sick.
Speaking of growing indoors, we recommended investing in a high-quality LED grow light and a timer. Set the timer to at least 18 hours on and 6 hours off during the vegetative phase. If you’re growing photoperiod genetics, you’ll need to reduce the schedule to 12 hours on and 12 off to initiate flowering.
By using pH up and pH down products, you can adjust your water for the optimal pH level. Make sure you have a pH meter or pH measuring drops!
The RQS Starter Kit comes with everything you need to give your cannabis seeds the best and safest start in life. It comes with a propagator and lighting, Easy Start seedling pots, perlite, and beneficial bacteria to encourage germination and growth. It even includes three popular cannabis seeds, so you can start right away! When your seedlings have reached 2–3cm, you can cut up the pots and easily transplant your seedlings into their growing medium.

Hi, cannabis needs fertile and well-draining soil. I did a quick search for nutrient requirements and this is what I came up with: “Industrial hemp requires 80 to 100 lbs/ac (90 to 112 kg/ha) nitrogen, 35 to 50 lbs/ac (39 to 56 kg/ha) phosphate and 52 to 70 lbs/ac (60 to 80 kg/ha) potash. Hemp prefers a sufficiently deep, well-aerated soil with a pH of 6 or greater, along with good moisture and nutrient holding capacity. Poorly drained soils, however, are not recommended as excess surface water after heavy rains can result in damage to the hemp crop. Hemp is extremely sensitive to flooding and soil compaction.” I hope that helps, best wishes and happy growing!
Hello, thanks for the information. Is there anyway to know what requirements should the soil have to plant cannabis? I have a field but i would like to know if it needs extra fertilizers and what quantities should i buy .
Growing marijuana on terraces
This is my first grow. I planted 3 clones in mid may. It’s the beginning of September now. They have gotten huge but haven’t flowered yet. It seems like they are getting plenty of sun throughout the day. What am I doing wrong? What can I do to start the flowering process?
