Holes in tubs??

Do you guys put holes in your tubs when using racks? My temps and humidity are perfect and dont wana screw that up but I don't want to suffocate my animal

Usually the space between the bin and the above shelf is enough for air exchange. Holes are generally for decreasing humidity in racks.

X2 as long as you have a little space air is getting in there, and if you have your temps and humidity down don't touch a thing!:banana:
