This is a really elegant setup. I'm seeing that Aroid/Hoya growers are also using these cabinets to show off their plants and keep the humidity high - I'd like to try this in the near future.
I'm envisioning something like a "show cabinet" where I have most of my (nonblooming) orchids in a tent and blooming ones in the cabinet to enjoy easily while they bloom? I love how our hobby continues to develop!!
