I am a first time grower with a lot of questions and few answers. I have a completely enclosed and sealed room. 6'x15' I added a duct to the plenum of my central air unit to bring air in and a 6" booster fan for exhaust. Mylar on all the walls and some ocilating fans. A pretty good environment. I put alot of work into it. For light I have Sun System 48" 8 bulb t5 ho fluorescent. It's great for veg, clones and seedlings. I tried to flower with it and got poor results. Nothing more then flowers, no dense bud. Should I go with a hps for flowering? Or will my t5 achieve the results I'm looking for. I was still using the blue spectrum t5s for flowering. Will the red spectrum t5s yield the same as a 400w hps? Or should I get an hps for flowering and keep my t5 for veg? I'm trying to achieve an oz. minimum per plant. Any advise would be appreciated. Thanks, happy growing.
