It'd be something nice to see or for someone to try! I used to be able to get QP's or a lil more in my rubbermaid setup I used to have. It's the one you see as my avatar and I have a couple of links from past grows.
Honestly, I believe it could be done w/ a decent set up and CFLs 42 watt and above. At least 4 per plant, and just speaking on my behalf...w/ I'd say 5-7 plants I think I could pull it off or be really close to it. Not gasing myself up, but just from trials and tribulations, these plants love good CFLs. I'm actually in the process of putting together my new grow room and I still use CFLs but Im about to aquire a 400 watt HPS and have two rooms. One with my HPS and one with my CFLs.
All I can say is never let someone say you cant do something, w/o at least trying it first
Light placement is key as well as the thumb thas putting everything together. I say someone start a thread...."CFL growers united: We're growing Brian Urlachers over here"
Not discrediting anyone here...but if there's a will, there's a way! And til next time, happy
