Autos, well I slowed my first autos with coffee, I now know that this is bad as caffeine is an herbicide,,, anyway the 65 day autos took 120 days to finish (after I cut off their coffee they grew)
Even though I stunted them, they were in flower by 21 days old under 24/0. If these girls responded to 12/12s, they may not be autos as it will only slow an auto,,, If they responded to 12/12s I would keep them there (ok I might try 13/11,,,)
