Zealious has the correct answer. By cutting down on your photoperiod you will have proportionally less photosynthetic activity and less yield. Many plants can actually flower under a 6/12 light regimen since it's the darkness that defines the photoperiod (the photoperiod is controlled by a molecule called "phytochrome").

It may be possible, however, to have a flowering period longer than the traditional 12 hours of light if during the dark period the plants are bathed in far red light (720-780nm). The far red light forces the plant to "sleep" and only by experimenting can one determine how far it can be pushed. So it may be the case that a flowering 16/8 or even a 12/6 cycle is possible. The only lighting source of pure far red light that I know of are high power LEDs sold in Germany.

Interesting feedback guys! keep it commin! I will look for that article i read on 6/12 photoperiod and post more tonight! I know you can add hours to the flowercycle,but if we could subtract and get a similar yield this would be awsome,this might need to be tried.I will build a small grow tent in my flower room and do an exparment in the name of science!hbr

Less yield longer flowering. The times the lights go on/off would just change every day.. it's not impossible to run light on a schedule that doesn't add up to 24 hours lol.

The other hours dont go anywhere. Lets say you start the cycle at noon Monday:

Monday noon til midnight dark
Tuesday midnight til 6am light
Tuesday 6am till 6pm dark
Tuesday 6pm till midnight light
Wed. midnight till noon dark
etc...
See, the other hours dont GO anywhere. You are just not using 24 hours a day for your base.
Plants dont know, or care that we use 24 hours as our day.
As long as the growspace is light tight, it doesnt matter.

As far as how this would affect production, I cant say, but am interested in finding out.

With a 7 day timer you can get a repeatable faster schedule, but then you have to work along the same light/dark periods. IMO 12/12 is worth the extra time.

I took some sour d clones to test on,will work out the details soon Hbr
