I see your herd instincts are strong and you would like to position yourself as the ram amongst the sheep. Lol bruh, that’s cute. You jump in and drop the “I’ve started thousands of clones” flex, then immediately pivot to “there is no difference in rooting, the difference is leaves sitting on top of one another” instead of addressing the actual peer-reviewed cannabis study I just posted. That’s not experience talking. That’s cognitive dissonance doing cartwheels.
You literally just read the results I circled in red. Removing leaf tips had the second greatest effect on rooting success rate. When leaf tips were removed, rooting success rate was lowered from 71 percent to 53 percent. The exact practice you are defending, trimming tips so leaves do not sit on top of one another, is the thing the science shows hurts rooting. Not "no difference". An 18 point drop. And three fully expanded uncut leaves gave 15 percent higher root quality with zero downside. The paper even concludes it is recommended that leaf tips not be cut in cannabis cuttings and at least three fully expanded uncut leaves for maximum success.
Yet here you are still clinging to the old bruh science myth because thousands of clones. That is the dissonance chief. You cannot square your seniority card with the fact that the plants do not care how many times you repeated the same mistake. They only respon to the actual physiology.
You are not protecting new growers from bad advice. You are protecting your ego from data that just proved the long timers have been doing it wrong.
Pride in your work? Cool

. Next time try putting that pride into reading the study instead of gatekeeping the forum like it is your personal pasture. The evidence is right there on the page for anyone actually open to learning.
I will keep my leaves intact, my domes sealed, and my success rate. You keep doing you ram. Just do not be surprised when the sheep start noticing the cliff. They are already fleeing towards it in denial, as they just admitted, unable to deal with the reality of facts.
