No, but the problem with pollen sacks is if you don't get to them quick, that crap gets all over. Make sure you check your plants thoroughly during harvest and curing for seeds, and scrub that room down, lights, ceilings, walls, floor, everything (just with water or vinegar) to get rid of the rest of the pollen. I'm POSITIVE if you have found this one, there are a few rogues around that you haven't seen yet.
