Here is the whole system. Long overview here... the grow container is about 20 gallons and holds 10 sprayers which act as the aeroponic nutrient delivery. There are also a number of drippers that sit around the stump to keep as much water moving over the root system. There are also two air lines that go into the basin, one that goes to an air stone and one that just pumps air into the container for good root zone circulation. The drain keeps the water in the bottom of the container to about 2 inches deep so that there is some water for the roots in case the pump shuts off but most of the root system hangs in the air. The water pump is powered by a 12v transformer and provides 40 psi at .5 gal per minute. The air pump is a 70 lpm pump ( a little overkill). The bottom basin holds the nutrient solution, about 30 gallons, and is pumped up into the container which drains back in by gravity. There is also a air stone in the nutrient basin which provides more oxygen to the water. The top reservoir holds freshwater that is used to top off the nutrient reservoir by a float valve.
