Cutting plants does affect yield. My best plant currently is my experiment of not cutting a single leaf or stem. Not only is it tall, but it is wide. And bushy. It grows faster and better then anything. Water more often and feed stronger. How hard is it to not cut your plants. I guess I only did it for all those years cause everyone else was. It is not necessary and reduces yield over the equal time frames. Nobody every mentions how long it takes to veg a super crop n top beast.
4 weeks is all it takes to get 3 feet tall and two feet wide, if you dont cut them. If you do, you can enjoy the benefit of permanently short plants.
I must note that each strain will act differently.
