chasv77answered grow question 5 years ago It depend on the strain, as my Blueberry nearly tripled, and it is an Indica. Since I have had both Sativa and Indica take off on me, I always plan for 100-150% increase minus the distance needed for light clearance to top of canopy. If you fear you are going to bump into ceiling, start LST now and carefully bend/tie those tallest branches down, to get ahead of any stretching. If you wait till critical mass, they will be too stiff and you may break them.
