Honestly find yourself a hydro store, pay cash. I dont trust sites or ebay. Apparently some one on these forums was watched, and the dea or whoever used posts to help prosecute the person all starting with something bought on ebay. personally ebay is a bad idea. Besides when u find a hydro store in ur area u can stop in and get what u need when u need it. It the #1 way to buy. And they will help you find what u need. They ussually carry everything u can possibly think. all of the hydro stores around me do most there business online, so when i stop in they love me cause im not ordering shit
