you can pull 3 Oz off Auto's just sayinyou couldnt pull 3oz from an auto though i suppose, so with femenised, they will just keep growing and growing, creating more bud sites until you decide to swtich it into flowering?
i would suggest doing a ScROG in a 10 gal tote. get a strain like big bud or something and LST/top at week 2sounds good, how long should i veg it for to get around 3 oz like a month? then switch to flower for how long?
