Heating season is upon us, and the orchids hate that dry air, so I tented the tank with some clear plastic to help keep the humidity in. I have the humidifier blowing some mist into there twice a day, but without the cover, it’s pretty much gone within an hour.
I tried having the maxillaria out of there, on the shelf nearby, and it just dehydrated to prune-like state within two weeks. So back it went.
The brassidium seems to be okay with dry air, as long as it gets its water. Semi-hydro’s been working out great for that one.
