Autoflower Cannabis Seeds

What are autoflowering cannabis seeds?

Autoflowering seeds (also called automatic or self-flowering seeds) switch to flowering automatically — independent of the light cycle, based only on the plant's age. This trait originally comes from Cannabis ruderalis, a hardy wild type from northern climates with short summers. Modern autoflower genetics combine that self-flowering trait with the potency and aroma of classic strains — without ever switching your light schedule to 12/12.

Benefits of autoflowering seeds

• Easy to grow — no light control needed, fewer things to get wrong, ideal for beginners.
• Fast to harvest — 8–11 weeks from germination to harvest.
• Multiple harvests per year — the short cycle allows several outdoor harvests per season.
• Robust & resilient — the ruderalis heritage makes autos forgiving of weather and minor care mistakes.
• Compact & discreet — short plants, perfect for balconies, small indoor setups and short summers.
