I think big, even manifold makes a difference....but is necessary, not sufficient....TEKNIK wrote: ↑Mon Jul 08, 2019 5:41 amDo you think the size of the trunk makes a big difference? I have told people a few times that I believe without a wide trunk to suck through water and nutrients it can only go so far but then they show me big results with tiny trucks so I don't know who is right or wrong
Also need a healthy, appropriately sized top and matching roots....
Cambium (xylem=water mvmt, phloem=nute mvmt) is located at the outer layers of the trunk...,as diam increases, so does circumference; and hence, cambium increases, boosting capacity for water and food movement.
But most important to bumping yield, imo, is the evenness of flow....that the manifold contributes...,maximized by controlling apical dominance with even tops (by pulling higher tops below lower tops, a dynamic process; it’s partly why my tiedowns are below canopy, which almost certainly requires wheels to rotate plant, blah, blah, blah).
Large diam provides capacity, but is more the result of great flow, than the cause of it....
One other point, i don’t think genetics itself has much to do, directly, with trunk size....i agree that genetics affects everything, but a healthy plant with no critical space or environmental issues will produce a big diam stem...all my manifolds almost completely fill out 3” net cups by harvest, regardless of strain/pheno...and i typically do 4 diff strains per 4x4 (unlike this grow)....
