Autoflower Cannabis Seeds

Autoflower cannabis seeds flower automatically with age instead of waiting for a change in the light cycle, thanks to ruderalis genetics in their lineage. That means a faster, simpler grow — most autoflowers go from seed to harvest in about 8–10 weeks and can be grown under the same light schedule from start to finish.

Their compact size makes autoflowers ideal for small tents, balconies and stealth grows, and their speed allows multiple harvests in a single season outdoors. Modern autoflower genetics have closed much of the old potency gap, with many strains now testing in the same THC range as their photoperiod counterparts.

Every autoflower strain we carry is feminized for all-female plants, covered by our 30-day germination guarantee, and shipped discreetly nationwide. Because autoflowers don't recover well from heavy stress, we recommend low-stress training and a gentle feeding schedule — see our grow guides for details.

Frequently asked questions

What are autoflowering seeds?

Autoflowering seeds flower based on age rather than light cycle, automatically switching to bloom after a few weeks of growth — no light-schedule changes required.

How long do autoflowers take from seed to harvest?

Most autoflowers finish in roughly 8–10 weeks from germination, making them one of the fastest ways to grow your own cannabis.

Can I grow autoflowers indoors and outdoors?

Yes. Autoflowers thrive in small indoor tents and are excellent outdoors, where their short life cycle can allow more than one harvest per season.

Are autoflower seeds feminized?

All autoflower seeds in our catalog are feminized, so they grow into female, flower-producing plants.
