Autoflower size is determined by the amount of rootspace that you have. I see this trend of auto growers pushing their plants in living soils in tiny little pots. The first thing seedlings do as they establish is send out little sense roots to figure out how much space (nutrients) they will have to then determine their size. They grow accordingly. Don't transplant, put your germinated seedling directly into a larger pot, like 50L or so, mulch, keep evenly moist and let it grow. It will provide! "Supersoil" or living soils in small pots, the plants will just be stunted in small pots.
