Advertisement I'm busy putting up thin foil insulation this week before it gets really cold, converting an unused room into a bug room. It's about a 7x7' room, maybe a bit larger. I'm aiming for a 74-78°F constant temperature, would an infrared heater work, or perhaps a simple heat lamp? I'm a bit unsure that a heat lamp could keep an entire room warm. What do you use for heating? I don't use heat mats, I keep mostly millipedes and heat mats are a big no-no for plastic containers anyway.
