I thought you were building your own systems, rather than buying commercial hydro systems? The only things I buy from a hydro store are the
nutrients,
growing medium (some I get at nurseries), pH test drops and pH adjusters, and if I need them the 3 inch baskets. But everything else I need for building my systems I get from local stores like Lowe's, Home depot, ACE hardware, Wal-mart, Kmart, Big Lots, Hobby Lobby, Dollar store, Pet supply stores etc. etc. etc..
