When I did a shotglass auto it started preflowering on day 12 and full blown stretch by 14. Container size means everything really. I assume it tricked my plant. But yeh you could induce blooming early with say but ignitor and a 12 12 lighting. But ive never done that. And honestly I have one in 12 12 and its just started to pre flower. Its 26 days old. So I don't know. Id say container size. But ill know soon enough im germing a bean to put in a 2 oz glass.
