Aquaponics Growbed Frame

Posted on February 13, 2011 by Brian Gallimore

Here are some pictures of the growbed frame I built for my aquaponics system.  I changed the dimensions on the fly because I wanted to minimize the number of cuts I had to do.  The bed is bigger than I had originally planned, and too big for the 5′ x 10′ pond liner that I ordered.  (3″ too big).  These pictures represent it still unfinished.  It is missing a 2×4 along the bottom and bolts on all the supports.  I’m not sure the external 2×4 supports are actually needed, but I wanted to make sure it doesn’t bust apart with 1000 pounds of water in it.  Lumber list and size information are below the pictures.
