Anytime I have grown a plant over 12 feet tall they either snap in half or completely fall over taking the steak with it. I would fim your plants while we have a good month of veg left.
I have about 30 more smaller 2 footers Ill do that to. These plants are very sturdy, I was worrying about them falling over but now seeing them theyve gotten really strong. We will see. I may do it to a few in this plot.
Nice they looking good! Anyways best of luck with the flowers, check out my outdoor grow thoughts and advice always appreciated Auto Flower Grow Dairy
Time to just let them go and not worry about them for a few weeks now. Top dressed the last of what Im putting on them this year. Gonna let the rain and whatever water I flush them in flowering do the work. They are growing about 1 foot per week.
