Definitely a work in progress, but sort of finished...
Took a TV stand I got at the thrift store. Removed the front, side and back panels of the top cabinet. The bottom part is perfect for storage and the power strip, etc. Painted it to look pretty
Replaced the front and side panels with plexiglass. For the top, I used thicker plexiglass. For the back I stained scrap plywood, then coated all interior surfaces with exterior grade polyurethane.
For the bottom, I used rubber for a shower pan to created a 2" "tray" at the bottom. I filled that with LECA balls, put window screen on top of those, and an orchid potting mix on top of that.
I made a sprayfoam background for one side and have some misc plants growing in pots I built into it.
I have LED lights on the top on a timer. I bought a 2 pack of fans, and it turned out they were connected to each other, so drilled holes in the top and am using both of them, one in the rear left corner, the other in the right front corner. I have the fans on a timer to run 3x a day for 15 minutes. So far humidity is running right around 70%, which is what I need.
Mounted a bunch of my orchids on cork and hung them up. It's been running around 10 days, and everything seems happy so far. Now I just need more orchids
Thoughts?
