Mr green setup questions

Im new to this im trying to do a hydro setup like mr green on his vids .I got most of the things down except the tray and resovuar tubbing stuff. I need a list of the parts needed to make a home made hydro setup. Like the exact measurement of the tubbing and fittings. This is what i got 400 watt hps for the budding room. T8 an led grow lights for the babys. budding and grow nutrients.A ph tester and ph down and uppers. what else am i missing? O and it doesn't really have to be exactly like whats on the video but something that works for a 2x4 tray.
