Lighting on a Timer


Hi,
I am just after some advice regarding times for the lights to come on/off through the day on a timer and whether what I have is ok for my plants.

I have a 330L tank which is quite heavily planted, I have co2 injection at 1-1.5 bubbles /second.

I have 3x T5 39W lights which are 2x D-D Aqua flora Power chrome and 1x D-D Midday 6000 both bulbs are rated @ 6,000K but have a slightly different light spectrum.

I currently have all 3 lights coming on at 9.00 and going off at 13.00 then the 2 AquaFlora tubes only coming back on again between 17.00 and 21.00. CO2 injection is on the same timer so is on/off with the lights.

Is this ok or am i harming the plants by breaking up the light in to 2 periods in one day?
Thanks

I have never seen any indication that a split photoperiod harms the plants in any way. Some people are convinced that it reduces algae problems, and, for sure, it lets you have the tank lighted longer during the times you are home.

Having the siesta time is really no different than having the sun blocked for a portion of the day by a giant shade tree. And as you know, in tropical conditions there are a bunch of shade trees.

In addition, the earlier start time and later end time may promote better growth as this would be similar to a longer summer day. I have no evidence yet to support this theory, comments welcome.
