My grow space is only 6 feet tall so I need to keep my end height about 4.5 feet. My tallest plant is currently at 3 feet tall I have four plants total two are about half the size of the tallest one. I would like to fill the screen as much as I can with the taller ones and just have a couple colas from the little ones. I have not topped her yet as they had a rough start but I was thinking either topping some off or just bend the main stem over. I want my scrog screen to be about 3.5 feet
