Re: How much passive ventilation is too much for plants?
The ExoTerra site lists vivs as "W x D x H"; I assume that people generally tend to do the same.
Yes, I think your plan is somewhere in the middle of my dart viv arrangements. I like the acrylic inserts, since I have extras of a few different depths precut and can swap them around depending on how a certain viv is looking.
Compared to many folks here, I get the feeling I run my vivs on the dry side, though they don't seem so to me.
I think I could turn and live with animals, they are so placid and self-contain'd.
