|What to do
For best germination results, put the Marijuana seeds on clean soaked paper towel, room temperature water. Cover the cannabis seeds with a layer of soaked paper towel. The Marijuana seeds should be left to soak in a dark warm place (65 - 80 degrees F or 18.5 C - 26.5 C). A kitchen cupboard is usually suitable. Check the cannabis seeds about every 12 hours. If the paper towels feel a little dry add a little water.
Usually within 48 hours the Marijuana seeds swell and split their outer seed casings. DO NOT continue soaking after the white, initial roots are visible at the crack in the seed casings. The cannabis seeds are ready to plant at this point. Soaking the Marijuana seeds until the roots are exposed can result in stressful, early root damage.
Plant the cannabis seeds in a clean, pH balanced medium. The medium should be loose and light with very good drainage. We recommend a blend of Perlite, vermiculite and sphagnum moss. This can be purchased premixed and can be used alone or mixed with light, sterilized potting soil.
Marijuana seeds should be planted about 1/4 to 1/2 inch deep in containers at least 4 inches deep to allow the initial tap root
to grow straight down. The container should have drainage holes to prevent drowning the seeding. The medium or soil should be thoroughly damp, but not soaked. High humidity is essential to good germination rates.
Keep the planted cannabis seeds covered with clear plastic. Place the planted Marijuana seeds under horticultural lights or a cold frame in a warm humid environment, (20 - 25 degrees C / 67 - 78 degrees F).
Remove plastic covers, once the cannabis sprouts have cleared the soil surface and the first true serrate leaves are forming. Keep medium or soil damp and fertilized with quarter to half strength vegetative fertilizer during this stage and watch'em grow.
Some varieties of Marijuana seeds will not germinate at room temperature but germinate fine at 90 degrees, about 20 degrees higher than room temperature.
