Nutrient comparison experiment; to LST or not to LST

My opinion is... It's not that science like to begin with.... Does LST increase yields?? Does defoliation increase yields?? Experienced growers write books on their information. But observations and personal experience seem to be a very powerful thing so it goes both ways... There is a certain natural element here. You can try to quantify it and put numbers to it. But it's like a beauty.. It's nature. It's growing a plant but it's also the plant growing itself. Try both.. Lst all the way :). Learn some new things.
