Why grow a fast finisher

A shorter flowering window means more cycles indoors and a safer finish outdoors before fall weather sets in. Fast strains also spend less time exposed to mold and pests in late flower.

Frequently asked questions

How fast do these strains flower?

Most finish in about seven to eight weeks indoors. Each strain page lists the exact window.

Does a faster flower mean lower quality?

No. Finish time is a genetic trait, selected here without giving up potency or flavor.

Are these good for outdoor grows?

Yes. A fast finish helps outdoor plants beat cold, wet fall weather.
