Aye have a 4 year old beardie called henrick. I recently got a zoo med 150w basking buld for his viv. Am haveing trouble getting the right temps tho. Ave got a 4ft viv for him. Am wondering were to put the probe for the thermostat? A cant seem to get the basking spot right plus keep the cool end at 80f? My basking spot is away up2 115f ( i know this is to hot) while my cool end is at 78f? When a move my probe further away from basking spot it just gets higher?? The probe is abt 8" away from basking spot. Am wondering if any1 can help me. He always seems to sit in cool end alot aswell??
