For a more accurate response, you may have wanted to differentiate between T5s and halides on the poll as people tend to treat them a bit different.
On my 90 the halides are on for 6 hours, and supplemental for 13 hours. (This was my vote answer) On my nano the T5s are all on 13 hours.

My power compacts turn on at 11am, my halides kick in at 12pm and run until 6pm, then my power compacts turn off at 7pm.

I had some fun programming my controller... maybe a little too much?
My times change daily, generally 8 - 12 hours. sunrise/sunset times are from Australia so that summer has short days here(less halide heat), winter has long days. I offset the sunrise/sunset times by 3 hours so that I'm awake when everything turns on/off. actinic - sunrise to sunset (10 - 14 hours) Left Halide - sunrise + 1 hour to sunset - 3 hours Right Halide - sunrise + 3 hours to sunset - 1 hour Center Halide - sunrise + 2 hours to sunset -2 hours Today the actinics where on from 9:18am - 10:10pm, each halide was on for 8hours 52 min. The controller was pretty good through the summer, I'll have to see how all the extra light does in the winter. Temperature's stayed great through the summer as well. I live in Vancouver though, so I guess I should still expect a heat wave this year, and also some snow in late may :S.

i voted 11,because 9 of my t8 tanks run 11hours(6hours 1hour break5 hours)
and 4 tanks running t5 going for about 9.5 hours but i have 5 tanks running t5HO and i only run 8hours and 2 tanks have t8bulbs but run only 6-7 hours. with this many tanks its hard to choose one time period.
