Day 4

I have 7 strong growthsfrom seedlings. Just airing them out cause the tupperware gets pretty warm n wet. I dont want the seeds to drown. In the mantime I'm trying to make a decision on a light. Its definately going to be 1000W...I dont know if I am going to get

a)MH system with HPS conversion bulb
b)HPS system with MH conversion bulb
c)conversion ballast system to take MH and HPS bulbs
d)used system on the cheap

Any opinions on these light system manufacturers- Econowing, Agrotech, Cool Sun, Large Horizontal,Sungro, Suntube, Super Sun 1 & 2, Vertizontal, Yield Master?

I'm looking at paying full price for one of those locally vs half price new from ebay VS. 1 lrg. /1000W HPS fixture (Hydrofarm)used /complete indoor gardening light set/w/ballast/aprox.24"x22"x12"DP. also ceiling auto tracking fixture for hanging light.both for $125.00?
