Hydroton Base for Modular Hydroponic Tower

Per the creator of this hydroton base : Place hydrotons (clay pebbles) in the bottom to keep humidity high. I don't know if this actually works, but I liked the idea. To make one compatible with this tower , I took the 80mm spacer and gave it a drainable bottom and a channel for the tubing. I rounded the edges of the channel for strength but also so no sharp edges would touch the tubing. I forgot to take a picture before I installed mine, but it went in just fine. Obviously, make sure you install it at the very bottom of your tower.
