so i have a 6x3x2 closed chamber built (well two of them actually) and i planned on using a CHE for ambient temps in both. one enclosure is gonna have a redfoot the other a baby sulcata. i have one 100watt CHE in one and i feel like that should be enough to heat to the low-mid 80s but its struggling to get past the 78° mark. granted this CHE is over 3 years old and has been used every single day all day since then so im thinking its lacking some power. do you think these could be heated with a single 100 watt che in each? should i go to a 150 watt?
