When to remove press n seal

[Rickys_Reptiles]

my clutch is on day 43 and a few eggs are starting to dimple a little but the humidity is still holding strong. For those of you that use press n seal under your lids, at what point do you remove it?

I suppose the question we're all forgetting to ask is: How large are the tubs you're using to incubate?

The rules will differ greatly if you're using a 5qt tub vs a 20qt tub.
