Stagnant air flow will ABSOLUTELY encourage mold. Air flow is almost more important than temperature as far as that goes. This is a quick run down on how we deal with larger quantities:
Remove all the fan leaves and excess stems and break the plant down into about 12"-18" chunks which are hung to dry. Ideally dry at around 70 with low RH good airflow for about 5-7 days. Remove from the drying line, and then remove any additional stems from the buds so that all we have are the untrimmed buds and place these in a brown paper bag to continue to dry the rest of the way - usually another 5-7 days, sometimes more, depending on the wether and the density of the buds. The brown bags help wick the moisture away evenly and slow the drying down for this last bit. A slow dry and cure produces the best smoke.
Once they are dry enough place the brown bags in two layers of hard or food grade plastic, like turkey bags or heavy duty contractor bags. The soft plastics, such as zip locks or trash bags, off-gas which is what gives bud a funny smell and taste when they are stored this way. Plus they are not 100% air right - air can seep in through the plastic itself. In the case of zip locks they actually have little pores built into the bags for this exact purpose.
If you use the larger contractor bags you can fit as much as 3 brown bags easily without squishing anything. I usually figure one brown bag will hold between 1-2 lbs when done this way, so a contractor bag can hold as much as 3-6 lbs if you load it up.
At this point be sure to store your bags in a cool, dark place just like you would wine. An in-ground storage tank is always nice for this since it keeps it at a cool and constant temperature.
