How much ventilation is needed on drying buds?

This might not be the correct spot to post this but some knowledgeable people hang out here.

I have all my buds drying right now. Do i need a fan blowing on the buds or will the portable ac vent and central ac vent be good enough to prevent mold. I have my drying temps at 66 deg and humidity at 50%.. Help if you know please.

yea as long as u have some sorce of ventalation in and out u should be fine low humidity is good IF thats any help let me know ima bout to cut mine babys down

I used to dry with one of those hang time racks in a spare bedroom upstairs. No fan, not even any special ventilation. I don't like how they make the heavier buds a little flat on one side though.

I think that you are fine, watching for mold wouldn't hurt though if you are worried. Your temp and humidity seem ok to me.
