i would strongly advice against buying that light. its not made for growing, its not going to produce the right spectrum and it will be too hot. if i were you i could do either t5 floros or cfls(you can get 42watts at homedepot 2 for like $3). you wont get the best density in your buds and it wont be the most bud you can get from a plant. but you can def grow some quality weed and if you had 2 rooms or felt like seperating your current grow room, you can easily do a perpetual harvest. just look at the growfaq or in the grow room setups or one of filthyfletchs DIY things, and just make it on a smaller scale.
