I'm intrigued by PL-L lamps but they seem to be more of a euro thing--limited availability in the US. So, I'll stick with T5 HO. Vertical does sound like a great idea for that space.
vertical grow... haven't thought of that! i'll check out 1000lights. i get the feeling im going to have to build this from scratch. no problem thought. i like projects!
any body have some links on how one might wire this thing up? im going to go for the 4x50 watt tubes btw. so i might need a little guidance. you guys are awesome!
