I'll be getting a 250w HPS for flowering, and I'd like to have some floros to use up until I flower my plants so that I can keep the lights close. The grow space is 21" deep and 30" wide. I'd like to have at least 150w of floros in here. Would it be possible for me to have a setup of 150-200w of floros, with total cost of bulbs, wiring, and mount coming in at under $75? Would CFLs or tubes be more economical? From what I've seen, the mounting for the 2' tubes are $20-$25 for a dual light 2' mount. This seems kinda expensive. Thank you all for any advice and help! Edit: Ok, after thinking, I've come up with an idea with two different routes. Buy a 2x4 for a couple bucks, cut it up. Make either a triangle or a square with it. Either way, I'd mount a 55w CFL to each side, on the inside. I'd then attach a piece of plywood or particle board or something to the top, and cover it with either mylar or paint it white. My only question now is... How would I mount these lights, and how would I make them able to plug into a standard outlet? Would this idea work? I found 55w lights for $16 @ 1000bulbs.com, I might be able to find them cheaper locally but I don't know. Three of those would cost $50~, leaving me $25 for mounting and wiring. This is the part I'm unsure of. Again, thanks for any help!
