Is This Enough Ventilation for Dubia Colony?

[stimulation]

This is 20-gallon tote from HomeDepot

Under is a heat mat that keeps one-side of the tote 85-90 degrees
humidity is about 62%
(both are measured with a probe)

the tote houses about 200 raoches (mostly nymphs

judging from the picture, is the hole big enough for ventilation?

the 62% humidity is without water crystals yet, will the humidity reach too high when i put in the crystals?

Mine looks bigger than that, and I still have a problem with my egg flats becoming moist.

well now i have the water crystals in the tote, and the humidity soars to 80% :shock:
but i dont have the problem of moist egg crate or food though
