So I have two red eyed tree frogs in a 45x45x60 viv with mesh tops.

The temps have been fine for the last couple of months but have now suddenly dropped 20% over the last week.

The only thing I have changed is adding some plants and some more substrate (wet)
i have doubled the amount of water my mister outputs, I have set it to spray ever hour but I cannot get the humidity to increase unless I manually spray it.

Im not sure if it’s because it’s going into winter and the general humidity of my house is changing or it’s the additional plants so I thought I’d ask here.

I need 70% humidity, only getting 50-55%

Any advice?
