In my climate (hot desert) it is ALWAYS hot. Our houses, no matter how you run the air, are warm -- like over 65F no matter what. For some plants I'd like to spread out to and join to my collection, I'd need a COLD terrarium. This is beyond dormancy, but for when my plants are actually active.
Has anyone ever tried out, or had luck with a terrarium that's cooled instead of heated while the lights are on, and the plants are growing and active? I've always wanted to add heliamphora to my tanks, but the cool night temperatures are hard to reach without active cooling of the terrarium.
What say you all? Is always being ambiently WARM just something to accept? Or can we do it "backwards" and cool a terrarium to grow temperate high-altitude CP's?
