um you smell bull shit, i just cut down 2 plants both 36 inches tall both grown under CFL's , i most certainly got 2.4 off one dry and 3.1 dry off the other. I must be a miracle, lmao, let me guess your another one of those guys!!! lmao,,you are a tool who thinks he has all the answers. I am a very very intelligent man who has found a way to grow for 40 bucks a month and i only feed water and mollases, nutes for only 3 weeks during flowering. I have averaged 2 ounces+++ off each of 10 plants i have harvested thus far. I could care less what you think is fact or fiction. there are guys on this website who grow mych more yeild than that with CFL'S . the fact that you think you know everything will never change the fact of my success. Stick to what you do, no shit hps is better, no shit no shit..duhhhhh,,,obviously.. but do not tell me what i do and do not do, just because you have no knowledge of anything but your own grow, you are jealous, or you are just a troll with nothing to do! 2 small fans..no co2,,lol,,no boom blaster..lol all your great products..me and my friends love my sensimilia..LOVE IT...i will go toe to toe with you on cfl growing any day buddy boy
