I'm having a hard time setting up a proper humid hide.
Since I've got two adult geckos, I keep two hiding spots in the tank: one is a hollowed out half log, which they like to climb on, the other is a big rock with two opposite entrances. The rock is what I place over the UTH, and both geckos seem to enjoy laying on top of it.
I tried constructing a humid hide from a butter container, just like I read about everywhere, but neither of the geckos were interested in going in. 
I've also bought some kind of moss. I'm not sure what kind it is, but it was from the reptile aisle at Petco. It's just labled "Terrarium moss." I've tried placing it in different spots in different amounts, but it dries up after just a few hours and blocks up the hiding spot.
Even the area where the rock rests on the paper towel dries up quickly because it's over the UTH.
What do you guys recommend?
