I know this gets asked but searching through all the post I have doesn't answer it all. I have a 400 watt MH-HPS by Vivosun atm in a 40"x40"x7' tent. The heat is too much, with a 4" inline and filter, where I am and I'm looking at replacing with LEDs. Should I buy cheaper ones such as MarsHydro or is name brands the only way to go? I have a limitied budget around $500ish. Also, should I buy a couple 300 watts or just one big one? If i get MarsHydro 300's I could buy 4 of them I think or maybe 2 of the Reflector 96's. I would love some info from people who have used these or have a lot of experience growing with LED's. Thanks everyone
