I'm leaving for a couple of days possibly four and I don't have a solutoin on keeping them hydrated but I know where I keep them the temperatures will be no lower than 75F. (I'm the only one who can care for them) Someone said what they do is put a cup of sand and spray it with water to keep longer humindity and moistiure for a longer time and sprays it when dry. More cups depending on the size of the tank. Anybody agree wit the suggestion I got, any Better suggsestions? I also thought if I could use spagnum moss or this bedding I use for reptiles called Eco Earth made by Zoomed, it's like potting soil but it's highly absorbent to put in a cup instead.
