Hi
@mixo420! Depending on the strain, you should flip to flowering stage once your canopy has spread up to 40-60% of your scrog net. For sativa dominant strains which tends to stretch a lot in preflowering stage, 40% would be better. For indica dominant strains which usually shows closer nodes and a short stretch, 60% will be fine. You will have to carefully tie the new growth everyday in order to have a flat canopy. Too many scrogs are poorly done and if not adjusted everyday in preflowering stage, then it becomes stem support, but not a real scrog. Hope this will help, happy growing! 👊
