I'm currently in the process of building a shade house for my orchids! I'm using pvc for the frame, a tan shade cloth, and wood & a metal netting for the stand. The frame is built and surprisingly sturdy. Today I cut the shade cloth to the sizes I need and put the grommets on (one of my orchids joined me outside while I did this). Hopefully tomorrow I'll cut the wood and netting and build my stand!
The shade house isn't that big because I only have about 16 orchids right now...but I know I'll need a much bigger one in the future.
It measures 6'h x5'w x4'd
