I think you are incorrect sir.
A plant has NOTHING in common with a human being. They "breath" CO2 in and release oxygen.. we do the opposite. They take their nutrition through their roots.. while I have none at all.. I have to eat and ingest things differently. A plant is different starting at it's cellular structure, cellular processes, life span, this whole "plants need sleep" non-sense, lumens have NOTHING to do with plants, if you cut my head off and stick it on another body it won't grow a clone of me.. see what I am getting at?
Removing branches is fine(called "lollipop-ing".. I do mine 2 weeks into flower I find getting the initial stretch out of the way, I can be more selective about which branches I take off), removing a few fan leaves is ok too.
It's even recommended by certain people.

Mind you nothing in growing is set in stone, and some things work better for some growers than others.. but this whole "nature is the best" crap I keep seeing has got to go! Generally speaking, there have been so many agricultural studies done showing how inferior nature is at growing superior plants and vegetation - starting with just a simple green house...To control temperature and water schedule alone produces faster growing, bigger, stronger plants - shows that man can create a better environment than nature provides. Why do outdoor growers bury a fish at the bottom of the BIG hole they dig and fill with THEIR soil mix with soil amendments to arerate and add nutrients to the soil?
Sorry, just feel like being critical today.. nothing personal.
