Ventillation holes in Sterillite tub...Help

[Highline Reptiles South]

I'm confused...if you want the substrate damp to the touch, you're probably going to get condensation in the tub???

This...

you don't want it too damp to the touch all the time. Maybe just when in shed. A better question is what is the humidity reading in the tub? In the same size tub i have only 10 or so 1/4 inch holes in the front of the tub. If I get condensation I know someone spilled their water dish or took a big pee
