First for hydro, Ebb and Flow

Hey guys, I'm looking into building an Ebb and Flow system and I ran across this site which seems pretty legit, http://www.growery.org/3043/How-To-Build-a-12-Pot-Hydroponics-System

anyone with any experience know if everything seems right on that site?

Also, does anyone know of any good books or resources I can refer to, to learn more about how hydroponics?

Thanks

All the info and then some is right here on the forum. I just built a legit e/f system with plywood, 2x4, and plastic tarp. Add pump, hose and timer.... Tadaa
