Keeping the humidity up for AFTs helps the shedding process quite a bit. I mist my AFTs once a day to ensure that at least most or part of their day has a higher humidity. If the gecko got lighter and was rubbing its nose/face then it was most likely shedding or about to. So keeping the humidity up is somewhat important. Normal room humidity is anywhere between 30%-45% so a mist once a day to get a good soak on the soil is enough to bring it up to about 60% which is plenty. And a misnomer that I've noticed is that people ask about how often their animal sheds. It's all up to them. You can tell when they need to shed, i.e. my chinese water dragon who I've had for 4 months and just went through his second shed. He obviously has had something wrong, and it was low humidity. But nonetheless, shedding is based on how fast they grow, which for Afts can be as little as every 10 days to as much as once a month. So just keep an eye on it, keep the humidity up a little, and help them shed, only if they need it.
