temps are huge in drying. If you have a drying space that is at a constant 65 degrees F and 55% RH with a slight breeze, and then you have another dry space that is at 75 degrees and 55RH with the same slight breeze the latter will dry more than twice as fast. Why? Because the actual volume of water that be held by the air is more than doubled between 65 and 75 degrees. With some circulation added the warm temperatures literally carry off more water from the surface of the drying plants. That being said though I wouldnt dry any hotter than 78 degrees, and slower seems better as a general rule.
