So I was wondering will I be able to use these for vegetating and maybe flowering? If so will I be able to use these alone for vegetating (I know not for flowering) or should I keep my CFL's on ?

keep your cfl's on you got the wrong sort of uv light you want one like this instead http://www.petzoo.co.uk/product_info...roducts_id=190

just get one or 2 to cover the area you got they're low wattage but they kick out alot of uvb light. use them as supplemental lights have alot more wattage of cfls. also watch your eyes you shouldnt realy have them on when your in the room

Better yet check out Ceramic metal halide

The purpose of adding uv light is to increase potency. The down side of uv light is decreased yield. Growing for yourself i'd say do it. Growing comercially it's probably not worth the reduction in yield. Less finished product to sell. good luck.
