water dishes

how big of water dishes will i need to maintain 60-70% humidity in my terrarium? medium, large or extra large? will i have to mist the terrarium alot?

Do you have it setup now and if so with what? And what is the humidity currently at? If not I would say try setting it up as if you would with your snake and see the results and tweak it tilll you get there.. when I used my old one it took a lot of tweaking to get it steady.

considering the amount of space i have, then adding the hide boxes, im limited to medium size water dishes...hopefully that'll be big enough to maintain the 60-70% humidity i'll need.
if not then i might have to mist...do i mist the substrate or the glass sides of the terrarium?

i dont have anything set up yet but im writing it all down so i will know what to do when the time comes...

i always do the planning ahead of time.

I think the best way to get it all down is to set it up I'm sure many have had different experiences in maintaining their husbandry in a tank so yours may differ and writing everything down is a great idea but id say te full proof way to know for sure is to go through it with it setup. But a medium dish may help and as far as misting i just misted down into the bedding but of course some water will end up onthe walls. What you can also do to help is a humid hide with spahgnum moss (spellcheck?)... I think you could also use beaked moss (correct me if I'm wrong). You could also put the water dish patrially above the heat pad as well and cover the screen top with foil. And tweak it all from there.

water dish over warm area, foil over screen, moss...gotcha, thanks.

now for the moss...do i stick it under the hide boxes & get it wet or scatter it around the terrarium & get it wet?

In a glass tank you could have a pool and it wouldn't do anything for humidity. Like chased said, if your resorting to a tank, use somthing to cover up 80% of the screen, such as plexiglas or foil. A prettier and less hassle method is to provide your ball with a PVC style cage that has glass doors on the front and side ventilation instead of top. You can find one in a suitable size for a ball for under $200.
I'm not a fan of misting, but if your misting to keep humidity up, keep it to a minimum, and make sure your enclosure isn't WET.
The best use for the moss would probably be a humid hide. Pick a hide in the middle area and keep the moss damp.
Also, I would take the water dish off the heat pad, your just going to facilitate faster bacteria growth, and in a tank its unlikely to help with humidity anyways.

ah ok thx
