A friend who also has a SQ36 says I can use mine to cold smoke salmon, cheese, and other products, tho he hasn't gotten back to me as to how yet. I'd make lox if I could cold smoke on the SQ36, cheese and nuts don't interest me. Does it take one of those smoker tubes? Maybe a couple pieces of charcoal and some apple chips? I'd imagine here in AZ it only gets cool enough to cold smoke a couple months a year. RAY
