I've been providing heat from the lights, The black light I have in the tank where the snake isn't coming out of the hide has been giving off great amounts of heat as for the light with the green bulbs is also giving heat off that. I have those sticker measure temps and i heard they arent good tomorrow i have a computer job to do and going to make some side cash so im going to be buying stuff for both snakes like a thermometer and so on.
