I have, probably a stupid question, about using the A MAZE N smoke generator. My husband and I are building a cold smoker and we are planning on using the A MAZE N pellet smoker to generate smoke. Is this all we need to use for cold smoking? Is any other source of heat necessary? I understand it is cold smoking but we live in the northeast and the temps can drop pretty low in the winter, will we have any problem keeping the inside warm enough?
