I tried growing autos for the first time last year, i was plesantly surprised.
Allthough the strains i tried were kinda unstable, potency was never an issue.
A photo yelding 90-120g is pretty good with a 15L pot and 4-5w veg.
I call bullshit on that one, dont think thats an auto, no matter the wattage.
"if" that is the case, i suppose they stumbled onto something revolutionary.
