Humid winter aquarium setup

[Dalachin]

Hi all. I finally set up a cool humid winter grow area in a small fish tank. Any suggestions? Do you think this is better than just sticking them on the windowsill and hoping for the best?

It is cool by virtue of the fact that it is in a converted porch room with no heating mat right against a window. I expect that in winter night temps will drop to the high 50s, right now I’m seeing 65 as a night low. During the day it heats up to 68-70, maybe more if it is sunny. There is one mister that goes off for 3 min in the morning and 30 seconds at 5pm. Two computer fans. One botanical leds light. I do have s second one that I could add.

Humidity reads 80-90% , is that too much? I could leave the top off (it us just a piece of plexi laid on top)

Current species:
Sarcochilus ceciliae
Paphiopedilum micranthum
Dendrobium hekouense
Dendrobium aggregatum
Dendrobium kingianum
Dendrobium parishii
Neofinitia falcata
(Maybe add sediera japonica?)
