let's discuss this, for real.
first off, where is the resin produced exactly? well it's produced at the site of growth. the resin is made in the resin glands. these glands fill as they mature. they don't move around the plant. hanging them upside down does nothing for resin production. 24 hours of darkness has no increased effects either. light creates photosynthesis, which creates growth. you aren't going to "trick" the plant. it's been around millions of years. it knows what it's doing.
