Hi! Not new to reptile, but totally new to snakes!!!
Yesterday we got a 3 year old female Spider ball from a guy who was rehoming her.
Set up: 40g tank, uth for a 30-40g, (reptile carpet over just the uth,) then bedding. One hide over uth, one hide on opposite side of tank. Water bowl and climbing tree central. 50 watt ambient heat night black light over the uth hut, 75watt ambient heat night black light over cold side. (Probe on hot side sits on the bedding inside the hut and probe for coold side sits right beside the hut at ground level.)

We are moving in august, but right now, the ac is wonky. 21 freezes us but 22 boils us and shoots the tank Temps to insane proportions.

At the moment, with the ac running game almost constantly, her hot side probe, (ground level inside hut) reads 93.5, so I moved that light a touch more central and it now reads 89.4. Her cold side probe (ground level, beside hut) reads 79.7. (I've come to the conclusion from research that cold side 78-85 is acceptable and hot side 88-95 is acceptable?

Are these Temps ok? Shoukd i bump the cold side to a 100watt ambient light night black light or will that be too hot?

She seems to prefer the cold side.
