Square Net Cup - 1.5 inch (36mm) grow cube

This is a hydroponics net cup that doesn't require clay pebbles or any other grow media to support the grow cube. The grow cube fits snuggly into the net cup. This design leaves a large area of the underside of the grow cube exposed preventing obstruction to root growth.

It fits within a 3 inch (73-78mm) hole and holds a 1.5 inch (36mm) grow cube. I have other designs and intend on making more if requested. Please comment the size (hole and grow cube) that would be best for you and I'll make
