Well I mentioned before that I thought this would be a good basis for a mini ebb&flow. So I was bored today and decided to put one together, as a proof of concept. Keep in mind that my home-made fittings are pretty crappy, i just dont have any proper e&f fittings. I just used what I could find around the house.
The one problem that i dont like is that the bottom of the top tray has a convex shape when i think happened then i drilled the holes and crammed the fittings into it, cause it not to completely drain (you can see this in the photo). I suppose this could be worked around by putting the pots on top of a piece of eggcrate or something...
FYI the dark blue ITSOs are cheaper than the "in style" colors, found it in a clearance-type aisle. Anyway heres the pics.
