well if the stuff I have put here does not make sense then Google is your friend as this is science, not mj forum hype. Simply search for what plants do when deprived of oxygen in the root zone ?
And experiments are your friend as well, so boil the roots on one and chop one and compare.
I know a lot of growers that do the boil thing, pretty sure none of em are gonna stop but then again no one is twistin no ones arm here, you either try it or you don't. Those that have tried it tend to do it for some silly reason, oh wait it speeds up the cure, that's why we do it
