Ive grown , as you say without flushing and i can tell you now that when flushed for 2 weeks it Definatly tastes better. The non flush plants left a metallic aftertaste and the flushed plants were smoother with more of the plants flavour coming through.
Ive been growing weed for years and been around many other grows and i can tell you from experiance that soil grown , flushed plants are the most superior tasting buds you can find on the planet.
I also know that 2 week flushed plants are slightly less weight than chem weed but the weight means nothing to me.. im not a dealer. Id rather smoke tasty weed .... and who told you that organic fertilised weed dosn't need a flush? Their pulling your leg m8.
Tell me plz, what physical homework have you done or are you just making this up from gathered info without actually testing your theory yourself?
You stick to non flush chem weed just dont try to pretend that its better and dont riddle this thread with more misleading information.
