Got to remember when they go into flower they double in height. Atleast and a lot of times much more. When growing photo seeds you control when to flower.
The rule for me is they will always triple in height if I plan for double. I have the light burn going on now to prove it too.
I did. That didn't take into account the stretch when crossing 12/12. And not 2 and not 3 times grew bush. More!
