Congratulations and some friendly advice, me personally I like 88 to 90 degrees, and 76 to 74 for my coolest. As far as increasing humidity, are you using some sort of reptile bark and other moisture retaining liter? I personally use paper towels and a very big humidifier. You also mentioned you had a humid hide with an inch of water on the bottom, that’s definitely more a swamp then a humid hide. You should just use really damp moss, soaked then squeeze the excess water out, with no standing water on the bottom. But yes please be careful with your temps, and best of luck.
