I made the following short video showing how everything works. If you are and DIY handy man, you know how to do it right away after watching this video:
I used a simple airlift pump made with a T-connector to feed water from the top of stacked grow trays, creating a water dripping flow. It is based on what is shown below with one exception: I added a one-way check valve at the water inlet so that it only allows water to come in and air cannot get out in an opposite direction.
See how simple an airlift pump is!
This photo shows it all, very simple to make

  1. Hello Aubrey,
    I am working on my first plant tower using a square 5X5 fence post. There is a lot for ideas out there. Fog and aquarium pump seemed to be the best and easiest way to get the nutrients to the top of the tower. So glad I found you air lift system! I am totally impressed!
    Been studying your videos and your website trying to get a materials list with different tubing sizes as well as the size of the T coupling. Not sure where I would find a check-valve that size?
    In my study I noticed the you are also a believer! That excites me and I look forward to listening to more of you videos.
    I appreciate any assistance you can give me!
    BLESSINGS, Norm Bozard (normbozard@aol.co)

    1. I need to approve your first comment before you can do that.
      BTW, you said “Fog and aquarium pump seemed to be the best and easiest way to get the nutrients to the top of the tower” – which fog and aquarium pump you like the most?
      Right now I am working on a larger aquaponics setup using rain barrels. Will post a new articles with pictures and maybe a video.
