well after quite a few successful soil grows over the years i thought id try nft, so i bought a complete system around £70 ( $140 ? ), nothing fancy, holds about 8 plants. Anyway harvested 3 weeks ago and i can honesty say after smoking weed for around 18 years it is the best bud ive EVER smoked. The yield is maybe a third + to what i was getting in soil. The ease of use is unbelievable, no hassles, no bugs, no dirt, just lush clean bud, the only thing is i wish i went nft years ago.
I cant vouch for other methods as i havnt tried em, but for me nft is the absolute bollox.
