sooo im almost done building a 4x2x2 cage for my jcp and i need to buy a heat pannel. which brand is the best and what size do you guys think i would need in a house that sticks around 70? i've never had a heating pannel so i dont really know what to look for but i know that its what i want for this cage. im shopping around i would just like some guidance from some people with personal experience. thanks guys!
