Deep Water Culture System - No Aeration Required

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.

Mind blowing

Is there a video that explain how to construct this system?

Thanks

What are these troughs you're using? I haven't seen them before

In your flood and drain cycle..what is the maximum height of water?..bottom of net cups?...this is useful for me

So its a "suspended raft", and not a floating raft?

How often do you flood the table, and for how long? Thank you.

What you're doing is inspirational as always, you mentioned flood and drain, is the water level controlled by Bell Siphon? Looking forward to more updates from you. Thank you.
