Trichome production seems to be a means of protection for the buds from UV, bugs, drought, etc, so it seems reasonable that some stress is better than not. I'm not sure how much stress you invoke though from reducing the watering of the coco without drying it completely. But, don't grow in coco so maybe?Also Azi, do you think that what I described will indeed cause a bit of stress and it might cause a nice response?
