I have bought everything but my lights off of e-bay.When i stopped growing outdoors and went dwc,i bought my first dwc setup off of e-bay as well.Now that i know how simple they are to make,i buy my tubs at walmart and make my own.
I build my own lights,i buy the ballast kits and sockets and lights from other venders.I can get my lights for about half of what you pay for them put together.OPH
