Dyi ?

I just made one of these: http://www.ball-pythons.net/modules....warticle&id=53

How long will it take to rasie the humidity?

If it is working properly than within the hour you should at the very least have a minor agustment to your Hydrometer. It could take 2-4 hrs to get the hu. up high if thats what you are going for. but if you see no improvment within 2-4 hrs something isn't right.
Hope this helped

Thank you. Should I be using warm water in the bottle?
