where does it say a grower will increase yield ten-fold? it says it's a way to 'maximize' your plant. and the side branches that eventually grow up towards the light don't turn into collas the same size as one big one. the collas are going to be smaller than one big one... but there will be more of them. you will increase yield, but it's not anything close to 'ten-fold'~https://www.rollitup.org/view.php?pg=faq&cmd=article&id=685
LST - Low stress training, look at the diagram.
