me and my uncle have some. the ballasts and hoods are legit, however several bulbs have been sent back.
my take on it I will continue buying the 600 watt hps bundles, I however will go to the hydroponic store and throw down 80-$100 on a good bulb before I ever start it up because I know in good time those cheap ass bulbs they throw in there bundles to keep the price down are junk.
customer service is an A+ all the way, no questions asked as long as your covered by warranty. Go with em but buy a "GOOD" bulb for back-up while you are waiting for them to replace the one that burnt out that got sent with it. "even the replacements are junk" HTG supply!
Good advice, hic. Thanks!
