I bought a new smoking gadget called an A-Maze-N smoke maker. Used it for the first time on my cheese smoke today. With ice, I actually saw a 5 degree drop in ambient box temp. Great for cold smoking situations. As a test run, I only did 8 pounds today, 4 of medium cheddar and 4 of Colby.
Box temp was 63 degrees when I turned it on this morning. 1.6 hours later and sitting at 58. ::)
Now time to wait for cheese to mellow.
