why cant you show some scientific evidence to the contrary? besides its not all about taste its about the burn, if theres still nutrients in the bud it doesn't burn as well, or it will snap and crackle, and if you don't flush your bud may harbor more carcinogens. you cant argue against decades of compiled texts and videos on how to grow marijuana, its in the grow bible for christs sake, high times's ready set grow series,
"the plants absorb what they need and convert it into energy. what other fruiting plants in nature are flushed?" fruit is eaten not smoked, totally different means of molecular breakdown and absorption
"if an organic grower didn't flush, would their crop taste like bat guano? if I plant jolly ranchers in my soil, will it give my harvest a fruitier taste?" no but it will taste different than if flushed.
I refuse to give you scientific evidence to this fact as it is about two clicks and a few keyboard taps away from you.
