I'm not new to chameleons or to this forum, but i have been away for a looong time. I am a new owner of a Mt. Meru locale Jackson's. I have a couple of other cooler weather chams but i can sympathize with Kracker. I live on the east coast and it is very hot here in summer, even at night. I can keep daytime temps in 70's and i use fans to help cool things down. My night temps are closer to 67 or 68. There is really no way to get night time temps into low 60's (short of a separate room air conditioner) and 50's are not reachable. I know that evening temps out west drop significantly at night but we are not that lucky here. I understand that these chams come from areas where night temps drop, but are there instances of longer term care where these temps can't be reached? The suggestions above are helpful and I really have nothing new to add. Just want to let Kracker know that others struggle with the recommended temps. Does anyone have input on stress colors related to heat issues? Love being back on the forum and reading all of the great input. Thanks
