I personally stress over this. I had a issue for years with my wife keeping her cloths in a closet in the room we use for drying. Some times I could get her to stay out and not go in and turn the lights on and get dressed and other times she would do just that and go in and turn the lights on etc... Over a long period of time and many crops I was able to actually show
her there was a difference in the buds if she didn't go in there and turn the fucking lights on while the buds are drying. So I have personally observed a diference and shown it to someone who constantly fought me on it and enough of a dif was observed by her to convince her that I wasn't just bitching at her for no reason.
