Your juvenile plants will be fine in their 1 gallon pot for the next 4 – 5 weeks of growth. Water moderately every day until moist but not soaking.
Using a chopstick, make a hole 1/2 – 3/4 inch below the surface, using rubber gloves very carefully place the seed in the hole taproot pointing down. Cover the seed with dirt.
Look for viable, plump seeds with a telltale “tiger stripe” on the side that indicates maturity. Larger seeds tend to yield more vigorous and hardy plants.
Maintain the seedlings in a sunny window, cold frame or greenhouse. As long as temperatures are between 60 – 80ºF, the seedlings will be fine. Dipping below 50ºF at night can slow growth, so you may want to bring the fragile plants inside in the evenings until they are hardier.
Prepare a one-gallon pot with a light seedling soil mix. Fox Farm Ocean Forest or Black Gold also work great If you’d like to add worm castings, you can do so in a ratio of 4 parts soil to one part worm castings.
Once you’ve found the plants you’re looking for, getting started with growing cannabis is easy. Simply follow these basic tips for germinating your seeds and planting them in soil.
Mature, viable cannabis seeds have a “tiger stripe” on the sides.
You will need to invest in a few pieces of unique equipment, but by using stone wool blocks, you can create a perfect utopia for germinating cannabis seeds. Soak the stone wool blocks in the same way you would a soil medium. The wool will retain the moisture and prevent the need to water during the early stages of germination. After the wool blocks are soaked, stick them in a plastic tray that also has a lid. Large cake tubs are ideal.
THE ART OF GERMINATING CANNABIS SEEDS
The Royal Queen Seeds Feminized Starter Kit contains:
Arguably one of the least effective methods, but it is still viable. Incredibly simple to facilitate, beginner growers may opt to germinate their seeds in a glass of water. Half-fill a glass or bowl with water that is approximately 22°C (71°F).
Planting directly into your growing medium prevents having to move seeds when they are at their most fragile. That first root tip is covered with microscopic filaments that are easily damaged. Given that both a cup full of water and moist paper towels are more prone to temperature fluctuations from their environment, planting in soil is a much safer option.
To prevent damping off, make sure to keep close tabs on the temperature and relative humidity in your grow space, and avoid overwatering your plants. Also, make sure both your soil and pots drain well.
This phenomenon, known colloquially as “damping off”, is caused by fungi like Pythium, Botrytis, and Fusarium. While these fungi can lie dormant in soil, they grow and thrive in overly wet conditions. Overwatering and high humidity, for example, are some of the most common causes of damping off.
These small, black, fly-like bugs feed off your plants and lay their larvae in wet topsoil.
HOW TO WATER YOUR SEEDLINGS
Inside that dark, hard shell, cannabis seeds house all the necessary genetic information to sprout and grow into big, luscious plants. When exposed to humidity and warmth, seeds are able to absorb water from their environment. This process is known as imbibition, and it’s the key to life for all plants.
Black or red in colour, spider mites live on the underside of leaves and sometimes spin protective webs around healthy foliage. They love hot, dry conditions.
While their roots are young and still developing, cannabis seedlings absorb water via osmosis in their leaves. To optimise this process, it’s super important to keep relative humidity levels at 40–60%.
