thats not what i wanted to hear..... and it seems to be false.
Not my problem.
I have topped some O. Haze several times but that's only to manage their height. Also applied a PGR for the same reason. They are 7' tall, still reaching for the moon but pretty much under control for what is atypical sativa type stretch. If you think your mutts stretch, you should try your hand at a pure sativa. No indica, pure sativa which can only be found in some of the beans I have - TFD's O. Haze, Dalat Vietnamese, and Zamal..... surely not from the pollen chuckers you guys do business with. For example, Neville's Haze is NOT pure sativa. It's been bastardized with indica genes. Doesn't mean it isn't an awesome high and a good grower, just trying to qualify what goes on with this (cheesy) seed biz.
Bottom line, my Haze which is the original haze done by Sam the Skunkman's Santa Cruz neighbors from genetics he sourced is <Acapulco Gold X Colombian Gold X (S. Indian X Thai)> and has at least 12 tops where my Peak19 backcrosses still have 4 main colas (tops). None of the Haze "tops" can be considered dominant leaders in terms of apical dominance. You need to study botany which includes hormonal processes and of course get some experience. I think you're falling into the same old boring category as 90% of the noobs in cannabis forums which is searching for tricks rather than learning what makes a plant tick. "Supercropping", LST, SCROG......pffffffffftttttttttt.
I could ask the same question, "why is LST such a big deal?" Whoever labeled the training method of LST is really indicative of the bullshit based on inexperience, feelings, and such that you find in these forums. Topping, in any form, does not induce stress. It only induces a redirection/collection of ho-moans. Noobies induce stress by not understanding what makes a plant tick...... applying the wrong cultural methods, using supplements, etc. "Low Stress" Training is a false statement. Then you have the pervasive myth/paradigm of flushing and the band plays on.......
Facts (experience) before feelings,
