I don't understand what you mean by divide the thc.. Its already distributed throughout the trichromes..
Furthermore, hanging plants after harvest does not cause more thc to flow etc. as other myths imply..
What does come into play with gimmicks like this is late life panic stress.. Stressing a plant via abuse, or extended dark periods just prior to harvest can cause it to produce more crystals.. It makes sense since its pretty much understood that trichromes are a protectant for the plant..
On the topic of hanging, a freshly chopped plant is still quite alive.. (Just like a clone) Growth processes will still occur for a bit.. Chopping/hanging is like the ultimate late-life stress.. I'm not saying its the ultimate method, I'm just saying there is nothing more stressful you can do to a plant..
