Yes, to my understanding. When I do a quadline, I generally keep nodes 3 & 4, or nodes 4 & 5.
I'm not into the "rules" of it... it's off-putting to me. People train a plant a certain way, then claim they invented it and make a list of rules surrounding their "invention"
That's where I sway from the pack on these things. I don't agree with writing a rulebook about how shit should be done. Each plant is completely different... I follow their lead, not the rules of a certain method.
Ultimately, you're looking for a plant structure based on 4 solid branches.
In actuality, the first "quadline" was invented by a grasshopper.... nobody knows his name; elusive little cunt.
Never been able to find him to ask specifics.
I've been reading journals here for years; I understand the "textbook" quadline method & will try my best to make a simple instruction. Ultimately, I've strayed from the textbook & just make my normal plants how I want them, some quads, some sexline, some mainline, some manifold.... They tell me what I need to know & I'll adjust as they talk
