Home Made Ebb/flo Air powered system.

I needed something to keep clones growing until was ready for them. I could let them sit in the propagation dome but, I wanted them growing while I figured out what to do with em. They bigger they are the more they are worth.

So I built this thing.

It is a large cookie jar, with an old oil tray on top.
I used an air pump on a timer to fill the jar with air and push the water out. Once the air pump turns off, the water drains back into jar.
The oil pan is filled with hydroton.

It was simple, cheap, and does exactly what I want.
What do you guys think?

Yea thats pretty slick.
