i bet i can find literally a tonne of different literature telling you that flushing is essential. means fuck all to me, i've done the experiments, i've flushed and not and the plants that weren't flushed not only looked better but had fuller rounder buds, ones that really looked plump.
no other plants are flushed, you could argue that most plants aren't ignited and inhaled but tobacco is, and the revolutionary moment in the tobacco industry regarding quality??? that was when they cured it properly and gave a nice smooth smoke with a nice white ash that wasn't rough or burned poorly. you are trying to say that happens because of flushing???? you can be dam sure that the tobacco industry is growing their stuff as quick as possible and are pumping as much nutes in as they can safely handle. still no flushing goin on.
sorry but its comlpete bullcrap, actually do some reading, maybe speak to a botanist.
