By section 6 of the Misuse of Drugs Act 1971 it is an offence to cultivate any plant of the genus cannabis in the United Kingdom without a license from the Secretary of State. Anyone committing an offence contrary to this section may be imprisoned or fined, or both. Please note therefore that germination of seeds bought from the Seedsman website without an appropriate license is illegal in the United Kingdom.

Currently at 7 weeks from Sprout and she looks lovely she's the one in the rear on the left can't wait to see what kind of flowers she gives me. I have placed several orders in the past with seedsman and it's always been fast shipping and never missing anything and included freebies I see myself shopping at seedsman for a very long time

I wasn't expecting much as a freebie from a giveaway, but they ended up being very yielding. They've taken multiple toppings very well and once I started them on a wicking base, they just shot up out of nowhere and bushed out. They're doing very well right now in flower. In the overall flower tent picture, they are the ones on the lower right side. It's only one plant right now.

Very healthy. The seeds germinated quickly. They start out building roots and look small and delicate, then they bust out and outgrow the seed pots (1gal). Huge fan leaves. With light feeding, I saw thick branching and rapid growth under SF 4000 light. I topped early at the fifth node to slow down the center. This allowed the side branches to catch up, and they did very nicely. I understand why it's called Guava Root because the smell was distinctly guava. The flowers filled in very nicely with continued light feeding (Fox Farm Nutes). Medium-sized plants. You will like the finished product.

Only 3 of the 5 seeds sprouted, so will produce a slimmer harvest than expected.
