korsitoanswered grow question 6y ago hello friend, of course, an autoflowering can come to bloom in the 6th even in the 7th week, it just happens that the flowering period will be a couple of weeks shorter, some varieties like fastbuds says they are harvested in week 9 but some are can lengthen to the week 12 or 13, and is because the vegetation has been longer, may be for the number of hours, if you want a plant to flower before you must lower the hours of light to 11 or 12. greetings.
