Your Local Hydroponics System Supply Store

You can find all sorts of wonderful things to make your hydroponics system at your local Hydroponics System Supply Store (read Lowes, Home Depot, Walmart, and stores that handle all kinds of plastic bric-a-brac.). In this picture from 2000, you see the nutrient tank (a plastic trashcan), PVC tubes used for channels and the system support frame, a plastic gutter used as part of the return system, gutter extensions usually used to run water away from the house at the bottom of rain spouts, and little plastic covered lidded container pressed into service to protect the conductivity meter from the rain. There is an automatic hobby doser mounted on the side of the tank and the hose is connected to a float valve.

There are all kinds of wonderful things in the stores that can be turned to use in making your systems. That is part of the fun of it, turning conventional things to new uses.
