Light schedule

Pretty much what Organoman said. But you can slightly increase you auto yield by going to a 14/10 cycle. Your photo should still flower and your auto will still produce a little more then the 12/12 cycle.

Your autos will be ok, but doing so will reduce their yield immensely. When you only have one grow space, either grow autos or photoperiod plants only and do not mix the two. Your photos won't flower at 18/6 and your autos won't produce much at 12/12. At least you now know for next time, it is one or the other. Hope this helps,........... Organoman.

You should be fine. Won't effect your autoflower too much, just won't be getting as much light.
