For my last 2 grows I have been drying my buds at 60-65 degrees and 60% humidity. It usually takes around 14 days for my larger buds and around 10 days for smaller ones.
I only grow in the winter time as keeping my temps and humidity under control is much easier for me. I also use a small fan in the tent just to move the air around a bit and it is never pointed right on my buds.
