Funny coincidence, but shortly after a reader of this blog introduced me to the somewhat startling idea of using a toilet tank flushing system for rinsing sprouts -- startling because in her photo it did not look the gardener was using new parts (ackkkk), I learned that a fellow named Jeff who has an online hydroponics store with lots of interesting information on his website builds "barrelponics" grow systems that are built partly with toilet parts--only I am pretty sure his are factory-new (!), using the overflow tank as a fish pond. It is so cute.
