Im not relying on one paper. Its just an example with actual credibility. The biological facts that it points to aren't invented by the testing... just confirmed by it.
Im still waiting for a credible source that proves cutting the leaf tips leads to higher success. Im sure its out there... just... nobody can find it.
I also take cuttings and get them to make roots. Maybe i have a photo somewhere i can post. I'll have to check. Its actuallt not an amazing act of magic only profi gardeners can pull off.
You are right. Healthy cuttings from a healthy plant have the best success at rooting. We should also state some more obvious basics while we are at it. Like cleanliness. Another "overlooked" bit of info is that rusty and dirty cutting tools don't do as well as clean and disinfected tools. Who could have guessed?
Plus, those well qualified people doing valid botanical research on cannabis and publishing their work in the scientific journals just have out of control egos. You should write to them and tell them you may seem like a rando on the surface, but inside you are actually have more cred in the online community of this businesses website, and they should check their out of control egos. Your rep is bigger, longer faster... louder, wider. You tell em.
You da man
