Is..this normal...?

They usually don't make that big a drop of grooming liquid from what I have seen but I doubt it's anything to worry over.

Well his sling had a pretty big drop going, which was why I voiced my concern.
And as you said your not used to seeing it in that excess? I know I ain't, and as far as keeping Ts with no ventilation holes, I have to say that I am surprised by your next statement.

For tiny slings in 2oz condiment cups I don't poke any ventilation. I've found that the cups I use doesn't seal tight and they get good air flow just from that.

I doubt they get "good" airflow, they may get some but it doesn't mean its ideal. And if you have a species that likes to burrow and you supply a lot of moist earth with no airholes it will get stuffy in there fast. I think airholes are pretty necessary but other then that I agree with your point of view.

I agree ventilation is important when you setup an enclosure.

What is ideal air flow?

Is it having enough air flow that:
the tarantula can breath without issue?
the lightly moist substrate and water dish doesn't leave condensation on the inside of the enclosure indicating it's stuffy in there?

The condiment cup shown below fits both those requirements without additional holes. Will it hurt to add holes? No, it likely wont. But what does it matter if the air flow comes from the gap between the lid or from some pin holes as long as you have enough of it?

These are cheap jello shot cups. The lids close well enough to prevent escapes but they don't hold in liquid if you turn them on their side. I've had 6 C. sp. hati hati slings (who love to burrow) in them since early last December. They were less than 1/4 inch (2i) when I got them and they are about 3/4 an inch now and doing great. The sub is lightly moist but not wet. I have to add a spritz of water to the sub 1-2 times a week to keep it moist.

If the cups sealed tight I would added aid holes for ventilation, but they have plenty without it.
