Hi Ginslee;
Welcome to the forum.
Not knowing your prior experience with smoking cured meats, I can interpret your post in different ways. Sometimes when people post they want to cold smoke, they don't understand the technical term. Since the flavor of smoke is subjective, I'll give you a range, and you should experiment with the lower end of the range. If you are cold smoking; keeping your cabinet temperature under 90°F, then apply 4 - 6 hours of smoke. I'm not sure if you are referring to the exterior color of the meat or the interior color. The cherry wood will help develop the mahogany exterior color, but since the bacon is uncooked it may be unnoticeable. If you are hot smoking 100°F - 180°F, apply 2 - 3 hours of smoke. Again the cherry wood will help develop that mahogany exterior.
The difference in smoking times is mainly due to the chemical reactions that take place at the different temperatures. Greater chemical and sometimes different chemical reactions occur at different temperatures. Also the heating element helps the bisquettes burn more efficiently, without the heating element you may find that the bisquettes are not fully burning. If you see post that require 1 - 3 days of smoke you are most likely reading a posts by someone who has a wood fired smoke house, or is making double or triple smoked bacon.
