Also, the Air/Nutrient pumps should be able to power more than one bucket. Am I missing anything?
why do you need a nutrient pump in a DWC? are you going to top/drip feed as well? you can find suitable ones cheaper, too. i get mine for 9.99 (when you're buying 8 that adds up.) and they work great pumping from a 3gal res through about 2 feet of PVC.
