I've been monitoring the humidity levels in my chameleons enclosure using 2 hygrometers that sync to an app on my phone. The daytime humidity levels are great during the day usually between 50-60% but for night the humidity drops way too much and I can't seem to fix the issue. I put some clear lining to cover up two of the walls to trap humidity but its not working. I set the mister to spray longer but it's not working. The humidity stays at about 40% during the night and it needs to go up much more. What else can I do to fix it? And for winter coming up and the nights getting cold the temperature drops at night and it's starting to get to mid 60s during the night. Should I be concerned for mid 60s temperature? During the day it's fine sitting at low 70s on the bottom of the enclosure and reaches 85 in his basking branch. He is an Ambilobe Panther Chameleon.
