sorry for another thread about this i just want my baby in optimal conditions at all times.
20 gallon terarium
i changed out my 150 watt bulb for a 50, and added a UTH with a temperature probe and a light dimmer from home depot.
warm side ambiant air 83 degrees
cool side ambiant air 76
probe from UTH- between 94-95
main concern was humidity here in the desert so i blocked the top of the screen with tile, enough to circulate air though, added some moss just sprinkled a little bit on the floor, and went to a lower power bulb and UTH, it seems to be holding for the whole day now which is great, i have a repti mister and do a spray once or twice a day.
another question i had which i couldnt find, is the uth supposed to be positioned under the hide? i have it in the front left corner of the tank, and the hide is in the back left, it overlaps under it a bit but still has enough room to sit in between the hide and the front glass
