I don't see why not??? I'm am doing that as well, untill i can get ahold of a good 400 hps lamp. Untill then i'm using the flouro in the bathroom and a little flouro along side so as to get the light in between. Its doing great in my bathroom and i make sure it doesn't get to much humidity too! Just watch that it isn't to hot for the plant. I have 2 but one is almost ready for the hps lamp...yikes need to get my lamp soon!!!..lol
