The 40' Biogarden with ebb and flow trough gives us the mechanism to create an air layer beneath the water level without completely draining the beds and without need for mechanical aeration. When using this sort of Air Layer Technique the roots get fully oxygenated with each drainage cycle and then rehydrated and nourished with each filling cycle. The Biogarden trough is 40' long, level and we use a Trickle Valve and weir with pump on a timer to regulate the up and down flow to each trough. Storage tanks are located outside, underground. One 1100 gallon tank supports the 4 troughs.
