What size enclosure do you have? I'm trying to decide what wattage of RHP to use. I plan on using flex watt for belly heat, but maintaining ambient temps are definitely an issue for my house. I'm drawing up designs for a 4x2x3 (lwh), but i'm undecided between the 40 watt and 80 watt models from reptile basics.
This is my first build so I have a more related questions, if you have the time.
