Quick egg tub question, the humidity is staying at 88% and doesn't seem to want to go higher. I covered the two tiny holes on top and the lid locks on tight with 2 latches. I have inside vermiculite with water under egg-crate and the humidity/temp probe on top on the egg-crate (it's the exo terra one) The egg tub is 5 1/2" tall, 8" wide and 6" deep. What do you guys think, I would like to get the humidity higher before the eggs. TIA
