Autoflower Seed Buying Guide

Why Autoflowers for Beginners

Autos flower based on age, not light schedule. No need to switch to 12/12. They finish in 8-12 weeks total, are generally smaller and more forgiving, and work great in limited spaces.

Feminized vs Regular

Always buy feminized autoflower seeds. Regular seeds can be male (no buds). Feminized guarantees female plants. Worth the small extra cost.

Trusted Seed Banks

Stick to reputable seed banks: North Atlantic Seed Co (fast US shipping), ILGM (germination guarantee), Multiverse Beans, Mephisto Genetics. Avoid random sites.

Frequently Asked Questions

Can you clone autoflowers?
Technically yes, but it's not recommended. Clones will be the same age as the mother, giving you tiny plants with little yield. Grow autos from seed.
What light schedule for autoflowers?
Most growers use 18/6 or 20/4 from seed to harvest. Some run 24/0 but plants benefit from a dark period. No need to switch to 12/12.
How many autoflowers can I grow in a 2x4 tent?
2-4 plants comfortably. Autos stay compact but still need space. Start with 2 your first grow to give yourself room to learn.
