Going to purchase a 10x10x7 grow tent. Struggling with the whole light setup. Wanted to go with leds but I think I'm looking to only spend on about 3 1000w units. The problem I'm having is deciding what lights to run. Are ebay air cooled hoods good? I seen some from yield labs I thought about buying then buying a good ballast and bulb. Now next question is what ballast and bulb ? I know I'm probably going to spend around $1000 on ac unit lights tent and everything else.
