Concept of Day and Night

Ok, so it is a known fact that plants use up CO2 during the day and give out O2. At night, they absord O2 that is present in the water.

My lights and CO2 (solenoid controlled) come on at 11am and turn back off at 11pm. So is 11am-11pm the proper day cycle for my plants or do they still consider Day to be during daybreak and night after dark? I am perplexed, cause if that is the case then my plants dont get the lights and CO2 up until 11am and they may have 'woken up' at 6am (day) and after 6pm dont not use the CO2, since it is night........

If this is a stupid question, my apologies in advance.

No Stupid Questions

The schedule of plants is driven solely by the light they recieve. If your lights come on at 11 am, then 11 am is their dawn. The process that uses CO2 (Photosynthesis) is driven by light, so heavy usage occurs only during bright light periods.
