i hope were not arguing on here...lol..
For some. For others, that maybe don't like dealing with the hassle & possible different phenotypes/statures of plants grown from seed, and the small amounts coming from each plant requiring numbers of plants that get into the federal mandatory sentencing statutes...
I used to have a newspaper clipping about a guy that I went to high school with that had grown one plant in a scrog setup that had given him 392 grams the previous grow. He also had one clone. Two plants (he would harvest the plant, grow out the clone and take a cutting during veg). He got busted because he was too stupid to pay his child support and his ex- turned him in. He got... probation.
So he made peace with the ex-, caught up on child support, and went right back to gardening lol (he did refrain from smoking for the period of his probation).
He did have to replace his equipment (a big light, nutrients, one large rubbermaid tote, and a $20 aquarium pump). Oh and some chicken wire. His meters were not in his GR and they missed them.
His lawyer portrayed him more-or-less as an idiot who was trying to grow for personal use that had gotten everything wrong (I can see it now, "...As evidenced, Your Honor, by the fact that the ONE plant completely took over his closet so that he wasn't even ABLE to plant the other tiny plant he had been wanting to put in there.")
So... Every person's situation is different. AF may well be the best for you and for a lot of other people but certainly not for everyone.
And if you were talking about AF plants, why not just go with 20/4 or even 24/0? I don't know that they'd finish any faster but they'd finish larger.
