If it is possible ideal temps for curing would be between freezing and the danger zone ( 33°F - 40°F ). That being said...for some people and some larger cuts it is not possible and the use of the next best thing comes into play... But only in colder months where the temp stays below 50 degrees, like a basement, cellar, even an unheated garage. You will run the risk of spoilage don't get me wrong here. But the curing salts are your safety net and being that you've used them I would say your fine. Again if POSSIBLE hold under refrigeration. Best of luck!
