We mentioned that our strains typically mature in 8 to 10 weeks, but Fastberry is anything but typical. It's quite rare to encounter a plant from this seed that takes more than eight, and we've even seen a few talented growers chop this strain down in the seventh week. Fastberry is perfect for beginners who want to learn quickly, and experienced growers who want to push a strain to its limit. Its short height also makes it ideal for stealth or indoor cultivators.
