The setup that you showed is a 2x4 frame, with plywood racks. Holes cut to support the 5 gallon buckets.
You buy the wood, I'll help ya build it. And, that setup would be perfect for your airpots, I think they'd slide into the 5 gal buckets(easier to water, feed. And no drips!).
No need to worry about lil ole me, as far as security goes.. I can keep a secret. .
Just something to think about. I don't ever really get to hang out with anyone anyway.
