If you can make them respond quicker with a 24 hr dark period thats good, but have you tryed giving them 14 light and 10 dark 3 weeks into flowering for 2 weeks then going back 12/12 ? I read it in Skunk or High Times? and it also in the Book below, book says there was a reported 10% more yeild and a week longer to flower. But what I would like to know, does it help the potency and flavor?
OBTW I do not care for Skunk Mag, it's a joke IMO.
