Depends how long I'm going to be gone. If it's just a weekend, and since I have adult chams that are eating every other to every other day, I just leave them as they are, since their lights and misting are automated.
If it's longer than a weekend and I can't take them with me, I have a friend that will pop in every couple days to feed them and refill/empty water from the misting system. If things like their lights and humidity are automated the only thing left to do is feed them, and this is easy for most people. I haven't had a problem finding someone who is competent to do this yet.
