Lollitopping is a common training term. Remove all but the top few nodes to resemble a lollipop. Michican you know this, why even pretend you don't? I've found it very helpful growing in closets/tents where there is one light and no side lighting. But again, it's done before the flip. Seems crazy to me to leave all those sites below and try to get light to them that will be a lot weaker than the light above because of physics. Almost useless light on the bottom.
