1. Shag, I don't care what you or any one does. I report, you decide. You're a big boy and must make your own choices. I'm not your nanny, more like a hard knocks teacher that raps your knuckles when you come up with crap like "I read that clipping the ends of leaves increases potency". Many do make choices based on the "he said she said" crap they read in cannabis forums and it gets them into trouble. "They're looking for love in all the wrong places".
2. I use Bonzi and never any cannabis specific products nor have I ever stepped foot into a hydro grow shop and am not about to start now.
3. I am a professional so that when I make a call it usually works as intended. That is based on a shitload of education and 40+ years of gardening experience.....I'm an old pHart.
4. That means that if if I'm growing a pure sativa or pure sativa hybrid and desire to control height, I start applications when the plant is quite young. The internode shortening influence is quite rapid and pronounced with Bonzi and lasts for a while. If things start getting out of control regarding stretching, then I act accordingly.
