I try to remove all of the underbuds, just leaving some of the 'baby leaf' growth. I don't know if it's something to do with the residual flowering hormones that remain in the buds, or what...but removing them seems to bring about the transition back to veg stage a bit quicker and smoother. Careful with leaving the 'popcorn' buds tho...They hold external moisture well, and mold can still set-in.
