Hello my friend is still in high school and is a genius in my mind he takes advandced biology. He has shown me a way to get plants to grow out instead of up. step1: plant is in veg stage and when it gets to height u want it at it is ready to be cut. step2:take magnifying glass and look at the top of the plant for a pistil (female) step3:the pistil produces a hormone that controls vertical plant growth and if u cut this it will cause the plant to focus its energy on growing horizontally (out) instead of vertically (up) i kno this may sound crazy but it is in his advanced bio book just thought i would share it. i have no clue about it so if someone else knows if this really works please comment.
