Here's my idea. I have 2) 150 watt mh from my old fish tank that I upgraded to t5s. I was thinking about doing just 1 plant bubble ponics with a 5g bucket. The whole air stone in a bucket of water. Need to do some research on nutes and stuff. I was going have a second bucket for reservoir. Do you guys run and auto top off? Or just fill up as needed? I wasn't going to have a box just yet. Planned on light proofing my closet somehow. Couple ocsilating fans and a couple computer fans on the light fixture Not sure if I can use metal halides? Any thought recommendations? Thanks so much Steve
