A couple quick questions regarding humidity. I'll preface it by saying that I have two AP enclosures each heated by an RHP. I use ReptiChip as a substrate and have a big bowl of water in the middle of each enclosure.

In the winter, I find myself constantly spraying the substrate because it will get down to 40% humidity. Luckily over the years I've only had about 1-2 not perfect sheds.

1. I have two thermometers that also measure humidity in each corner and the one under the RHP is always 10-15 % lower. When trying to keep the enclosure in the >60% range, should I aim to get both ends in this range or is one end good enough?

2. Anyone use a humidifier and care to share your experiences? This seems like it may be easier then having to spray every other day.

3. When I do spray, the humidity will spike and condensate on the glass for about a day. Hopefully this is ok.
