Yes but what do you guys think if top the plants and let em two weeks longer in vege would it be more yield?
I understand your Q I think. You will find a similar yield if you did each of the various growing styles and did a great job of each one. What changes is what we call that style.
On one end of the spectrum is manifold and mainline, training an indoor plant into an 8 spoke plant that is equal to say 8 of the SOG plants. So 8 to 1 comparison. It takes much longer to veg a big version of this style plant.
SOG is the other end, where as fast as possible each plant is just a single main cola. Superfast veg here, where more plants and likely more floor space is used to compensate for the speed bonus.
And anything in between are other styles. So if you want a lot of smaller, fast grown plants but want to top them and grow maybe half as many as a typical SOG, that works just as well.
Terminology matters, so if you say you want a SOG, you DON'T want to top or do anything except prune.
Most growers grow plants "as-is" their first time, then pick one of many styles to try after that. If you have no plant count worries, go for anything you want to try.
Doing a good job, whatever you do, determines yield more than style itself. If you grow well, then sharpening your methods will get you higher yields.
