I know this thread is a year old, but I'm looking for an answer and since many of you use Mist King I figured it was worth asking!

I'm building an enclosure for my boa, and it's going into a room that is fairly dry (Around 30% RH). When I kept my BP's in that room I had to mist their enclosures daily, and it was a real pain. Since Mist King setups are only around 100.00 or so, I was considering adding a system to the enclosure to do my "once a day" misting for me automatically.

My first question is this... The enclosure is only 12" high. Do the spray heads spray a mist fine enough to cover a large are of substrate, or do I need to add several heads? I suppose another way of asking, is this. If I put the spray head on the top of the enclosure, how large and area (approximately of course) of the substrate will it mist?

Secondly, how far down from the top of the enclosure do the spray heads sit? The enclosure is only 12" high, so if the spray heads sit 3" below the top inside surface, then I'm afraid they may be too low. Thoughts?

My current plan of action is to use a 1L garden pressurized sprayer. It doesn't take long and isn't much work - but no work is even better
