I started building my system. First step is the fish tank. It will be about 1400 gallons. And in order to get a good head start, I have plans to fill it up with my pond's water.

I have read a lot about grew beds. The one I think I build is fill and drain, I do not know exactly what it is called, but I have plans to build the grew beds about 3 X 8 X 2 ft, and fill with river rocks for about 18 inches.
We do love all sorts of vegetables and greens, but I do like to know what grews best with fill and drain system.

Thanks for all the good comments.
