I have heat in both . He gets heat from the 100 watt megaray and a and a 50 watt Halogen bulb and a 100 watt CHI on 24 hours . Then a oil filled heater keeps the room at 79 - 81 . The humidifier will keep his cage and room at 55 /- during the day and 65-75 at night , set on medium . and i have a small fan that rotates circulating the air in the room . The temps are perfects in his cage . If in need to i can add glass to half his cage . on very cold/dry days, i do that too .
