Regarding fluffly nugs. I recall a technique used back in the day when lots of folks were growing under crappy lights. One way to add resin, virtually doubling weight, was to crimp the stem but not break it, just below the bud and let it hang down. After a day or two of the plant trying to cope with the injury by sending copious amounts of resin to the area, the bud would be flooded with sticky, and much heavier.
This isn't used much today. I haven't heard anybody discuss it here. But there is a book from a few decades back with detailed info on it.
I'm not really into gossip...just curious.
