Who are the professionals? We all know that the data on the internet are obscure, pointless, and often times advertising gimmicks that are not even based on actual science. I find it interesting that point out doing a test and saying it would be "pointless", how do you think science is done, by a bunch of guys and gals in an underground bunker wearing white lab coats? Science is done by those without funding from some corporate sponsor who tells you what results to focus on. I believe Migrower even pointed out that most experiments are done in controlled environments, to add to that, most times, the results are skewed for continued funding from said sponsor. So what would be a credible person? Well, I think anyone that would do the experiment and produce results could/would/should be considered credible. You want to learn to grow, pay attention to how tomatoes are grown, or better yet go to burpee, good info there, maybe just consider that cannabis is a plant under the same rules as any other plant.
Migrower, who do you think perpetuates these myths about growing? Most not all, cannabis sites will tell you that pruning is a wonderful idea, they are wrong, try out the experiment, you were in college, you do know how to set up an experiment? You also know how to be objective? Weed sites are not accurate when it comes to gardening, at times I find flaws even at gardening sites, their information is much more on par compared to cannabis sites. Tell me, what would you do if after pruning your plant it catches a virus of some sort? Better yet, it looked healthy so you cut off a bunch of bottom leaves, branches, ect. , and now the top leaves are turning yellow and dying? Truth be told, you seem intelligent, yet, like most of us, have been suckered in by big corporate advertising/propaganda tactics.
