Basically, I am showing how to build the root chambers, rez, and feeder lines for your system. Depending on what is available in your area, pick your own misters and pump to match. No one builds them all exactly the same.
Every system will vary to suit your own needs and space but here are the basic materials for this particular one:
Main 6 inch pvc pipes
I am using schedule 40 6 inch diameter PVC pipe. You can get this at large plumbing suppliers. Just ask around at Home Depot type places, if they dont have it, they will know who does. As for cost, it varies. In Canada it was anywhere from $5 to $9 per foot. Schedule 80 is too thick and expensive.
I am also using 3.5 inch netpots, spaced 6 inches apart, therefore you will need a 3.5 inch holesaw. 3 inch or 3.5 inch pots are ideal. The mass of your roots will be in the tubes, so dont worry about the pots being too small (They are just anchors really).

Your 6 inch tubes will be joined by rubber couplers with hose clamps. You can find these where you buy your PVC along with rubber end fittings to close the tubes off. *See last pic


The sprayline is held in place by grommets or rubber corks with holes drilled through them. You can find something that will work in the plumbing section, or stores that sell beer/wine brewing equipment (a huge selection of rubber corks and stoppers) Choose your sprayline, misters and plugs before you begin drilling holes!

Since each of my tube sections is 15 feet (3, 5 foot sections joined) I needed the same amount in 1 inch PVC.
1 inch Feeder tubes




It has 5 holes drilled in it that fit the drain spigots of the tubes. You will need to drill an access hole for nutrient access and the intake line of your pump.
You can also see the business end of the feeder tubes, they are all joined together in one common pipe that leads to the output of the pump, which will soon be sitting on the floor beside the rez.
