Split Photoperiod?

[holoublahee]

So my tanks are on an 8 hour photoperiod, but I rarely get to see my tanks with the light on since I leave home for school early and get home pretty late. I was wondering if I could set the timers to turn on, say, 6:00am turn off around 10:00 then back on around 4:00 and off again at 8:00pm.

Would this have ill effect on either my fish or plants, or is it the same an 8 straight hour photoperiod?
