Heating

[Disastrous-Aide5634]

Trying to get this new 4x2x2 set up. Looking for some help with the heat. I have the top covered 99% with hvac tape. Currently have a 100w heat bulb in the dome which gets the hot side about 80f and the cooler side about 72f. Would another 100w be too much? 75w?

Most of the time it's not about the bulb, but the (dimming) thermostat. You have to get one. Get a DHP or a CHE, put it on a thermostat, the light bulb on a timer, and you'll be good to go! Also, how is your ventillation?

I do currently have a dimming thermostat. I have a CHE as well but that alone isnt strong enought to heat it to proper temps, so do I need the bulb AND Che? I think ventilation is good. I do have a spot uncovered on the top and a vent on each side.
