Where do you start with this?
It is sad that sooo many "experts" have bought into this "myth". That's right-"MYTH"!
Growers in major magazines spout it. Book authors spout it......That doesn't make it right!
I went out to Cali in the early 70's and lived on a commune or collective, north of Frisco.....It was a magical time! The Dead, dose's and big tittied hippie chick's everwhere (My wife say's I still get a hard on from smelling Patchouli). I met a really cool guy who was growing on this "collective". This guy was beginning to breed and had no problem teaching me the "ropes" of growing..I followed his methods with great care and became an excepted grower of some fine weeds. Flushing was a given as the road to quality tasting smoke. This "guy" began to draw attention to his work by the 5O.....He left and we kept in touch......
Years later he is in Amsterdam, a world class breeder and seed maker. I spent time with him this past winter....We spent time arguing on our favorite disagreement - FLUSHING!
Over the years I took the time to TRY new things with an open mind - All sort's of things. I took time to research the science behind some of these things and the reality of the science behind them...I tried side by sides and flushing is one...
I have news for you....This "flushing" thing is BUNK, BULL SHIT, HORSE HOCKEY, and NOTHING MORE THEN A MYTH, brought on by well meaning people from a bygone age, using logic . That is trumped by science that was not even considered all those years ago!
Flushing is so ingrained into many of these so called "experts" from these old days with the modern grower looking back and seeing these guys as growing "gods". If they say to flush, well then it must be true and no other thought is given to it!
Greg, Jorge, Logan, Stitch and Ryan to name some, Not to mention The "REV" or Danny Danko. All spout or have at one time, that you must "flush"......They can not be more wrong......There is NO "must".
Flushing takes the nutrition away from the plant when some nutrition is most important! This old school, left over myth must die!
IT'S ALL IN THE DRY AND CURE, for that clean taste and burn your looking for.
NEXT. To those that say, I've tried it and in my side by side's, I've tasted a difference! That's because in the science of your brain. IT found one. Because it was looking for one! In testing new products for market. Years ago, a major testing and marketing company. Found that people would FIND a difference in a product being tested along side others for comparison. EVEN IF THE PRODUCTS BEING GIVEN,,,,,WERE THE SAME THING!!! The mind will FIND a difference if given that task.....Even if NONE exists!
Nowhere in plant science is anything ever "flushed" in growing it for whatever reason......The "curing" of fine tobacco's is a science unto it's self! Why is Cannabis different? It's NOT!
If you "feel" you must. Well then, do what you "must" but, once at least. Find a "proper" curing method, grow the plant out with out a "flush" and try that for quality and yield......
