Honestly, grouping plants together helps tremendously with the humidity. There are a couple of them that will always need more (for example, it seems no matter what I do I can't keep my alocasia stingray or philodendron aurea thriving) but truthfully, I should be keeping those in a different environment anyway. Most of them are absolutely fine. During the winter it does get really dry in there (I'm in zone 4, so heavy and long winters) so I run a humidifier if it gets below 45 on the hygrometer, but it usually doesn't because they're all so grouped up.
I'm more surprised that my cacti seem fine with the humidity levels and never get signs of rot. I dont know if it helps but I keep all my dry/arid plants on one shelf, and my more humidty-needing ones grouped together away from the arid ones.
I have a thermo/hygrometer but it always seems to stay stable.
Thank you. It really is a stress relaxer. It took a while to get everything set up for sure. This room has about 110 plants in it, most on the shelving on the wall opposite of the windows. I've got another 60 scattered in another room. I like bringing nature inside :)
170 plants?! and here I am feeling super overwhelmed with 7 of them, hah!
on a slightly joking but also sort of serious note: do you have spreadsheets to keep track of them all? is there a lot of variance in watering schedules, or do you have some auto watering..?
Yep :) I used t8s (or t5s? I can't quite remember) for the shelves. I posted a photo from the chair view in the comments, maybe that will help picture them better. There's another shelf on the wall beside the chair that's kind of hard to see that has lighting too. Honestly if it weren't for all the lighting, I don't think half of these plants would survive.
