Is there a guideline for how much veg growth seen following flipping to 12/12? I’ve seen comments that some plants double in size. Is it strain dependent?
Usually double, I always mess up and don’t leave enough room for that… lights 8’ in the air bolted to the ceiling
It’s usually pot dependent type thing.
When they hit that stretch mode double in size is common can triple stretching reaching trying to get pollinated. Auto or photo, I have been in the same shape as @PharmerBob by not leaving myself enough room . At that point all you can do is bend the tops over.
Or cut the ceiling out
