To plant cannabis seeds indoors, first soak the seeds in lukewarm tap water for 12 hours. Discard any seeds that float to the top. Then, place the seeds on a damp paper towel on a plate with 1 inch (2.5 cm) of space between each seed. Cover the seeds with another damp paper towel. Keep the seeds in a spot that remains between 70-80°F (21-27°C), and spray the paper towels with water whenever they start to dry out. The seeds will sprout in 2-3 days. When they do, fill pots or a growing tray 3/4 of the way with loose potting soil that has a pH between 5.8 and 6.3. Press the soil down lightly, leaving some air in it. Then, use a pencil to poke 1 inch (2.5 cm) holes in the soil. Place the sprouted seeds vertically in the holes and fill the holes with potting soil. Water the soil thoroughly and place the pots or tray in a spot that’s always 75°F (24°C) or warmer. Set up a grow light over the seeds and leave it on at all times. Water the seeds every day so the soil doesn’t dry out. The seedlings will emerge in 2-4 weeks. To learn how to use cool white grow lights to help your cannabis seeds grow, keep reading!
About This Article
During the harvest, each plant was carefully examined looking for molds. Fortunately, and despite having a relative humidity rather high during the bloom phase, any plant was attacked by fungi. A good ventilation, and the regular use of Trichoderma during the growth stage greatly helped to avoid the risk of mold on the buds, which often start growing in the substrate.

So, generally we recommend you to germinate 15 or 16 regular marijuana seeds for every square meter in small flowerpots. Grow them for few weeks and then switch to bloom, right before removing the males and transplanting the female marijuana plants into the definitive containers. Normally, we use 6-10 plants per square meter during the flowering stage.
