just saying your advice to grow shorter plants is a lil irrelevant, my example was only to show you that sometimes regardless what you do a plant WILL be tall, if it's in the genes. Flowered outside at 18" and ending up to be seven feet high is not the norm, but what my point was, is even on top of a VERY sunny mountain, some stretch no matter what, and shorter plants aren't always better
So that being said, hes growing a haze... so it's more than likely going to be tall, even if he flowers early
