mr4tonanswered grow question 6y ago Hey bro! I was also mastering this method.
I believe that a lot depends on the growing conditions, like the height of the box and the growing area.
What light?
If it's LED and there's no side lighting, then it's optimal to bring the canopy into a single plane; there are simpler methods for that.
But if it's HPS and there's room to grow, then mainlining is very, very simple and takes a bit more time than LST, but the training time is three times less!
Regarding the question: I remove the ones that stretch (the show-offs). The ones that don't stretch and are well-lit, I keep 👍
