6qt tub dripping from lid?

[KingPythons]

I have 4 tiny holes for venting in the sides of my tubs and I get zero condensation build up on my lids until the last week or so of incubating.
90% humidity is fine for hatching ball python eggs, they do not "need" 100% humidity which is probably what you have when your dripping from the lid.

I remember doing a hundred in humidity but it was towards the end so it didn't matter. So is 90% through out the whole incubation ok ?
