Germination of cannabis seeds
How to germinate cannabis seeds: Complete guide ????
Successfully germinating cannabis seeds is the first step towards a bountiful harvest. In 2026, growers are increasingly returning to seeds for their genetic stability and legal origin. High-quality genetics from verified seed banks ensure a quick start and strong plants from day one.
What influences successful germination? ????
Germination requires three basic factors: moisture, darkness, and a stable temperature (73–77 °F). Once the shell cracks, the main root emerges, which is most important for the stability and nutrition of the plant. Remember that seeds stored in a dry, cool, and dark place will retain high germination rates for many years.
Proven germination methods ????
1 Combined method (water + napkin)
Leave the seeds in a glass of standing water in a dark place for 24-48 hours. Then transfer them to a damp napkin on a saucer. Once the root is 1 cm long, plant it in the substrate. This is the most effective way to soften the shell and promote growth.
2 Peat Jiffy tablets
Allow the tablets to swell in water and place the seed in the hole with the root facing down. They are ideal for beginners because they have a balanced pH and minimize transplant shock.
3 Direct sowing into the substrate
Place the seed directly into moist soil or coconut fiber. However, this requires precise control – the substrate must never dry out, but it must not be overwatered either, so that the seed does not become moldy.
4 Rockwool
Soak the cubes in water with adjusted pH. Since Rockwool does not contain any nutrients, it is necessary to start with very light fertilization earlier than with soil.
When to start growing? ????
For outdoor growing, we recommend germinating during April and May. The ideal time to move outside is after the "ice saints," when nighttime temperatures consistently stay above 16 °C. For indoor growing, the timing is entirely up to you.
Legal notice (2026) ⚖️
