I have some beans in my aquaponics system! I had planted these when I made a hot compress a while back http://mike.creuzer.com/2011/12/i-cant-find-my-hot-compress-so-i-made-a-new-one.html
These where the black beans that I picked up off the floor when I was done. I just tossed them into my aquaponics and hoped they would sprout. They did. I now have beans.
I think this is pretty cool!
