For one plant it works great. I had problems trying to grow more than that. I yielded about 2 ounces of one Kush plant my first grown using the Phototron. I used soil, not the medium they recommended and the BIGGEST tip is to hang 3-4 BIG CFLs from the cord that hangs from the top into the tank. You get WAY bigger yields. Check my pics that is Platinum OG I grew in the Phototron.
