Lighting hours

[Lampshade]

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 have 2 Maxspect G2-160 watts LED (Bridgelux) for 72 bowfront. a 3 stages timer set as:

10 am -10 pm 3 watts 20K
12 pm - 8 pm 3 watts 14k
3 pm - 6 pm 30 watts 10k

seems fine for the last 16 months.

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.
