I switched bedding, now I have questions!

[Physician&Snakes]

I recently made the switch from reptibark, to Harland aspen bedding. The main reason is that, the amount of aspen I get is 20x more than I get with a large bag of reptibark, and they are the same price. I love the new bedding too, it seems to hold heat in a lot better than the bark, and its a lot easier to clean.

However, since switching I've noticed a rather large drop in humidity with my snakes. Normally its 60-65% in their tubs. Now its always around 40-48% which I'm not a fan of.

So for all of you aspen bedding users, how do you keep your humidity up? I think I may have too many holes put into each tub, and if that's the case its and easy fix. How many holes do you guys use for your tubs? I currently use 15 quart, 32 quart, and 60 quart tubs for my babies, juveniles, and adults.

Any input would be much appreciated, as I currently have 3 females in mid shed, and I would really hate for them to have bad sheds because of me.

Aspen can be hard to humidify and not mold...it has zero resistance and little retention, I only use it sand boas. 40% should not be too hard to fight though, probably just moderate misting two to three times a week should do the trick, many people I know that use aspen will also use slightly larger water bowls as well.
