Background: In the past I have always been a window sill grower, more for the hobby than the product. But arising suspicions and a want to pursue (and save money in the long run) has driven me to start growing indoors. Right now I have a 4'w x 4'h x 2'd cabinet divided into two 2' x 2' light-tight sections coated in Mylar. I can't afford to have massive lights running all the time and don't really want to have overheating and fire as a concern, anyway, so I'm stuck with Compact Fluorescent. I recently ordered this beast. Will this be enough for a 4 ftÂ² SOG style grow? Also, can anyone link me to a site that offers a flowering counterpart to this bulb? Thanks for taking the time to read through this, I have everything ready to go so I'm very anxious!
