Re: quick bit of help please
It may lower it a bit, but if the humidity in the room is high it won't do anything. Personally, I'd just leave it alone. Yes, it's high but if the substrate isn't wet then you don't worry about it. It's not a big deal to have it a little high, a little low and you could have problems.

An oscillating fan will be your friend when regulating humidity in tubs. I set mine about 4-5 feet away from the tubs and run them on the slowest speed to keep air circulating through the tubs...

Yes add more holes to the tub :)
