Germination
Cannabis seeds need 3 factors to germinate successfully: moisture, warmth and darkness.
Ideally you should use filtered rainwater, but if the tap water of your area is safe to drink you can as well use it for germination purposes. The amount of chlorine added to the water kills bacteria and impurities in the water, which helps in reducing the risk of infection. If the level of chlorine is too high it will slow the germination process but it will not kill the seedling. If the local tap water supply is not safe to drink then do not use it to germinate seeds. Bottled water, without additives or gas, is a good source of water for germination.
For best results, fill a glass with clean water at a temperature between 18 and 25 degrees (room temperature). Drop the seeds into the water. The seeds should be left to soak in a dark place at a temperature between 20 and 25 degrees C / 67 - 78 degrees F. A drawer in your kitchen, away from heat sources like an oven, is usually suitable. Check the seeds after 5-10 minutes and tap down the ones that are floating. If they continue to float just let them. After 12 hours move the seeds onto a plate, between two wet layers of cotton or toilet paper.
If you use toilet paper use multiple squares to form a thick layer. Leave the plate in a closed dark space (the same drawer would be fine) and make sure to keep the layers moist. Do not soak them.
Usually within 48-72 hours the seeds swell and split their casing shell. When the white, initial root is visible at the crack in the seed casings the seed is ready to be planted. Soaking the seed after the root is exposed can result in early root damage. Plant the seeds in a clean, pH balanced medium (5.5-6.0). Point the tip of the root downwards. The medium should be loose and light with very good drainage. We suggest a blend of good quality soil and Perlite*, or Rockwool*. Cannabis seeds should be planted 2-5 mm. deep, using containers at least 10 cm 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 wet, but not soaked. High humidity is essential to good germination rates. Keep the planted seeds covered with clear plastic, or keep them moist with a sprayer every few hours. Place the planted seeds under horticultural lights or a cold white neon tube in a warm humid environment (20 - 25 degrees C / 67 - 78 degrees F).
Remove plastic covers, once the cotyledons have opened and the first true leaves are forming. Keep medium or soil damp and start fertilizing for optimal growth.
