Indeed! The trouble you faced was not having the room to spread it out. By itself you def would have been able to keep it to at least half its height.You will do much better, I’m sure. Some of my early spreading of the stems got messed up during the stretch, when both plants were fighting for spatial domination. If I had just one plant, or at least more space, I would follow Shed’s reco to continue to tug, pull, tie down, and totally subject the plant to your will. Keep the chosen colas spread out, and prevent any one cola from achieving apical dominance.
