Auto Seeds has been dedicated to breeding autoflower cannabis seeds for over 20 years, we produce the best ruderalis genetics you can grow. The flowering trigger is built into the seed, so the grower does not manage a light-cycle change. But, there are some strains that take longer.

Autoflowers can grow under any light schedule but perform best under 18-20 hours of light per day from seed to harvest.
