Whew, tension tension... I have an open minded opinion on these theories
1) Pictures are only as honest as the people taking them (Did you lollipop or use any other tech.?) Not saying your dishonest just stating how paranoid I am.
2) Can't really argue with science... On the same note I love selective pruning. Not for an increase in yield so much as letting enough light through so the plant reaches maturity evenly.
3) Great thread none the less and props on taking the time to do a controlled experiment for us to see.
4) The only way I know how to increase yield is from optimal conditions CO2 and plenty of (Cu) for the assistance in carb. metabolism etc. etc. and (Si) which with inadequate amounts will cause an approx. 50% decrease in yield it usually exists in the form of Silic Acid and is absorbed in this way. oh and of course P and K are always big in the yield department
but nature life everything is about balance and moderation. Veg time there are alot of factors people X X my mind is going crazy thinking about everything that effects yield so its not as simple as a magic technique in my opinion.
My 2 cents!
Again great thread i will +rep ya in a bit I am a lazy stoner but you have my word +rep is coming
