I'm working on converting a solid wood cabinet to separately house 3 BPs with bioactive setups. It will be lined with vinyl to prevent wood rot. I've never done set up like this before and wanted some opinions. Because it's pretty solid I am concerned about airflow and ventilation so my idea is having a vent up high in each enclosure on the left close to the radiant heat panel. Also on the right/cool side lower in the set up additional ventilation (pegboard on snek side) 2 questions: 1 Will the isopod guys try to get out of the lower vents? Is there a minimum distance the vent should be up off their floor? 2 would it be beneficial or not to have a really small fan, like PC cooler type fan on the cool side like an exhaust controlled by a thermometer or am I over thinking that?
