korsitoanswered grow question 6 years 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.
