Not worth it for 10-12 plants, you definately want HID (high intensity discharge) lighting...the MH and HPS they were talking about before...
I mean, you're getting in over your head maybe...lol...Ok, so if you wanna use the big boy lights...you're gonna need some sorta ventilation system, drawing out the hot air and pulling fresh cool air in...
Ok, you you wanna do it all with CFL's? Well, it's gonna take like 20-30 individual CFL's to do like 10 plants probably, and thats gonna create a lot of heat as well, so you're still gonna need some sorta ventilation system in the works...
