Intresting question. I had a small clone at one time that was near harvest and a HEAVY rain came and washed away a lot of the pistils on the exterior. It rained that hard. I gave the plant a couple more days to get the excess moisture out and during those days it seemed that a couple of pistils came back but not near the number that were previously there. The smaller amount of pistils didn't seem to have an effect on potency but the look of the bud was definetly different.

Happy Toking :rasta:
