That's not really an extra 2 hours, because that's 14/26, instead of 12/24. So that's really an extra 55 minutes of light per actual 24 hour period. If that works, I can see how it might be worth it, but getting off a 24-hour format where the 'day' for the plants would drift two hours each actual day would be too hard on my brain. You'd have to keep a chart to know where you are on the 14/12 cycle each day to make sure you don't open the box when the lights are off, and you'd have to adjust your schedule 2 hours later each day to handle feeding and such. If I grew for profit...maybe I'd try that. Since I don't, that's just too much headache for me, whether it works or not. Heh.
