I've got a big bowl of water and also a homemade humidifier, and half the top of the tank covered.

Gio spends most of the day in his cool hide, slithers around in the evening, basks under his light for a bit, and retires to his warm hide till morning.

Any ideas on how to increase heat/humidity?
Humidity in the low 50's is fine, you don't need to be in the 70's unless Gio is shedding or having problems shedding. I'd say the warm side definitely needs to go up more. What kind of thermometer are you using, where is it mounted, are you using a thermostat and what kind of cage are you using?
