To add weight or tighten-up fluffy buds, some growers crimp the stem below the buds and letting the buds hang down for a couple of days before harvest. By crimping, but not breaking the stem, it allows the plant to flood the buds with resin in a desperate attempt to heal the injury.
Maybe I am too high so I am confused and unable to comprehend what supposedly takes place when a stem is crimped in the manner you describe ....... so please explain to me how by crimping a stem below or near a bud, which will severely limit the flow of moisture and nutrients to the bud due to the damage to the plants vascular system in that location resulting in slowing down the movement of the very things that are relied on to produce the terpenes that travel up the trichome stalk into the trichome heads and become resins, terpenoids and cannabinoids, will be increased by hampering/slowing/limiting their flow to the buds?
Moisture and nutrients are not pumped up through plants from the bottom or lower portions. They are drawn up through the act of transpiration, evaporation through leaves and other plant matter. There will be nothing below the crimp to increase pressure to force more of what you believe you want through the damaged/crimped location. The act of transpiration will be slowed down because there will be a limitation at those points, the crimped points, there will be a choke point that will slow down the upward draw of moisture and nutrients. As slow as plants heal and overcome such damage there will not be sufficient time for the damaged vascular system to repair itself. So how and from where does the gain or increase come from? How does what you want to get to the buds get from point 'A,' below the crimp, to point 'B,' that being the bud at an increased rate rather than a decreased rate?
Too me that sounds like if you wanted to get more fuel to your fuel injectors, or carburetor if it were an old car, you would crimp your fuel line limiting the flow of fuel.
It just does not make any sense to me at all.
And when it comes to things that; "some growers" do, well "some growers" will boil their roots or pour boiling water into their pots to 'force the THC in the roots, stalks, stems, branches and leaves into the buds and up into the trichome heads' even though THC, and all other cannabinoids, are produced in the glandular trichome heads and not in 'the roots, stalks, stems, branches and leaves etc. "Some growers" do insane things because they do not have the slightest clue about how plants actually grow and work.
