I saw this ballast system for HPS that seems pretty nice and quite cheap, and the 6 year warranty certainly grabbed my attention. I was just wondering if anyone knows them and has used their ballast systems before?

Thanks
no cant say i've heard of maryland hydroponics although it does sound like a good deal...theres so many company's selling HPS lights its hard to know whats good an whats bad..if you worried it isn't as good as it seems contact mdhydro an see if its been through tests that live up to safety regulations...or some kind of product quality stamp (not by the manufactuer)...but id say go for it!! happy growin'!
