So aprox a year ago my idea to turn my closet into a grow room ended badly. I considered it a total failure and the whole loss came to around $500. While not my first grow by any means...it most certainly was my worst. I started with a combination of both CFL's and a few LED systems, totaling in at about 200 watts. I then, like an idiot, decided to toss in a 150 watt hps assuming the height of the closet (4x6x10) would dissipate the heat through simple convection. How wrong was I. My beautiful white widow clones, that were doing so well just vegging under the cfl's and LED's were dead within 80 hours. The reason I stuck the HPS in the room was due to the obvious fact I was getting almost no canopy penetration. I want to conquer and put this albatross behind me. Do you guys think T5's would create too much heat for this small closet? I wouldn't know, I've worked with quite a few systems but never attempted to grow and flower with T5.
