I bought the V3, or maybe it was the V2 dont remember now, mini stealth economy grow box. Its running temp was 99 degrees F, it had a 400 watt HPS in it. Now that i know a bit more about growing, i know that it would have been impossible to grow anything in it. I raped the box for parts, and built one that is 6 feet tall. I heard that the ones from BCnorthernlights are good. I thin kits bcnorthernlights.com or something like that. They are expensive but ive heard good things about them. whatever u do dont buy from HGH they are theives at best. They dont have refunds. My box ended up costing me 1300$ and it would definitly not support life. i spent an extra 400 to buy some things and made a whole new box myself. Good thinig money isnt a big deal, or i would have really pursued a refund from them. Use a close it would be better. Good luck man.
