Sounds like a fun project...without a pump everything would have to drain to waste, unless you connected them in series using gravity to maintain a reservoir I guess that would be more of a DWC system though...about all I could find online was this http://www.littlegreenhouse.com/accessory/garden.shtml...and it doesn't look too promising unless you were to drain to waste. I'm interested to see what you come up with though.
