the cage plan i have it to use a false celing to keep my bci from coming incontact with the heat bulbs. my problem is that i am worried i will lose too much heat and humidity due to too much ventilation. i planned to have the back wall of the cage 16" tall, leaving a 8" space for lights between the top of the cage and the false celing. this means that there will be an opening 8" x 4' on the back of the cage, which i feel is way too much ventilation. the only solution i can come up with is to make a door on the back of the cage opeing, either hinged or bypass doors to allow for regulation of ventilation, although i think a solid door will be best.
please let me know if you think im on the right path or if you have any other suggestions.
just for reference, the cage will be 4'x2'x2', 1/2" plywood, 1/3" top, and have 1/4" plexiglass bypass doors.
