Ive only tried the auto flower plants with my current grow i have a 60 day wonder and ill never gro another auto, i may be a little to old fashion for these strains but they just seem like an whole lot of work for something thats doin its own thing. I guess if your worried about the plants getting to big or something like that then there good but to max on yeild try something thats good with lst method or scrog that way you can still keep them small/short, max out your yeild and you can control when they switch. Id prolly recomend ak47 tried and tru. Just my 2 cents
