"if" the humidity was close to 100% there would be condensation on the sides of the tub and probably lots of it.
I use lots of water, some substrate and a piece of light diffuser panel for the eggs to sit on.
My tubs are vented and not sealed and with 90% humidity(which is perfect to me) I have some condensation on the sides of the tubs but not too much.
I don't see any condensation built up on the sides of that tub, did it have before taking the pics?
They look like they're dimpled from low humidity to me.
