Amazing
Ordered 5 seeds got 5 different phenotypes. 100% germ rate and the best in the biz customer service. When in doubt order you won’t regret it.

Fun fun fun
I started one of the white widow extreme and grew it indoors until it got big enough to clone . Off just one single donor I was able to harvest 110 plants that I transplanted outdoors. I live in the U P of Michigan so I have a limited growing period but they all grew perfectly and though they only reached 4 feet in height they frosted over and harvest was much better than I expected.

my favorite to grow with great harvests

Adaptable and resilient
Super easy to grow outdoors, less preferred by bugs and disease. In containers these shoot straight up and produce fast. Plants much taller in the ground, hold well in the wind. Great choice for a late crop outdoors.
