I have a hydroponic grow box I've been using for lettuce and herbs for a few years now. Decided to try for some cumbers and cantaloupe, so i moved it outside. Both of these plants are climbers, and this box is just not suited for that.

To make this you will need a printer with a rather large print area. M4 screws of your choosing for the supports. 4 36inch long 3/4" dowel rods. And this old hydro box. https://smile.amazon.com/gp/product/B01MS6U1UF
