For cannabis seed germination, all that is needed is water, air and warmth. Under 21–30°C, seeds typically sprout within 2-7 days, while temperatures above 31°C may negatively impact germination. The process begins as the seed shell cracks and reveals the first tiny root, followed by the emergence of two cotyledon leaves reaching towards the light.

Overwatering is the most common issue during germination, causing oxygen depletion and seed failure. The substrate should be evenly moist but not soaked. Excess water should drain easily to prevent drowning the seeds. For Rockwool germination, misting or drop-by-drop watering is best, only when the top 3 mm has dried. Keep in mind that young seedlings can absorb only minimal water, so too much moisture can do more harm than good.
