hey eddie, you'll get it. i work as a service tech in hvac so heating and cooling issues interest me. humidity is basically controlled by moisture and ventilation. too much ventilation lowers humidity, not enough ventilation you have too much humidity. high temps can also dry out the air (109 deg. might do this) heat tape, heat pads and flexwatt provide good heat without overdrying. you can check your hydrometer by breathing on it it should rise considerably. a humidifier in the area the cage is should also raise moisture. temps above 90-95 can lower humidity. properly setup and ventilated you should be able to keep temps and humidity in check with a spray bottle. i spray my green trees twice daily and my bp once daily. just going to have to experiment a little

hope this may help

thanks
