Just my opinion based on my experience growing weed since 1972, but I do not agree that root bound or root stressed plants bloom earlier or differently. As for "auto" or early blooming from cramped roots, I have not seen that. With landraces or with modern hybrids. From seed or from clones. Though I have never needed to clone males. I only grow standard photos. No autos or fems. I bonsai (root bind) my males as I do not need gobs of pollen. I size them up to 2 gallon pots max, whereas I size up females to 15 gallon pots. The males tend to start blooming slightly earlier than females, but that is the same with full size males which I have also grown in the ground in different years.
I have also seen claims that Mediterranean varieties like Lebanese red are "autos", or partial autos because they bloom earlier and finish in September. But that is not the case. They are true photos, and they just bloom with less decrease in day length. As opposed to say SE Asian or Colombian strains that bloom way later with a large decrease in day length. Either of these strains can be forced to bloom when light deprived. I have forced blooming with light dep for some decades now.
I have also found that bushy pinched/topped plants or bent stem plants will produce more weed than if they are left tall and slender. Many have noted this growing here in the west US, so it is a common commercial practice. Its an energy thing. More sunlight falls on a wider area. Simple physics. More sun, more sugars for the plant. The plants also stay more compact and easier to manage, spray and harvest. And here you have to keep home grows out of public sight, so tall plants are just not an option for many. I grow in greenhouses so I have to pinch my plants to keep them lower growing. Otherwise they get to 12 feet and become too hard to manage and they touch the greenhouse ceiling and rot from condenstation.
As for the "my way to the highway" posts here... get real. None of us is as smart as all of us. And there are many different methods to grow plants. If you think we are all as dumb as bags of rocks, you just sound like Mr Ego himself, Dave Watson. Seriously.
