ebay grow systems blow. My new 600 watt isn't any brighter than my 400 watt. Are these bulbs crappy? I bought this iPower 600w 600 watt HPS MH Grow Light System Set Kit Dimmable Green House BEST | eBay
I was just going to buy one myself. Simular kind of set up. What kind of warranty to they give you? (if any)
