Recently, I moved the 4′ x 8′ box that I was using to grow hydroponic lettuce and other leafy vegetables. It wasn’t easy to move by myself. So I’ve decided to build some smaller boxes, 32″ x 48″. These will be much easier for me to handle. And they will also allow me to do some testing of various fertilizer types and combinations.
The boxes are made with 2 x 6 x 8 pine lumber and 7/16 OSB sheeting (plywood). I’m using 6 mil black plastic and 1 inch styrofoam insulation. I did go ahead a put a coat of stain on the boards to give a much better overall presentation. If all goes well, I’ll be using these boxes for a very long time.
