- I can see how 24/0 is better than 18/6, but my theory is a bit complicated...i'll explain.
Photosynthesis creates food energy, but Respiration turns the food energy into energy to grow and for other life processes. Photosynthesis, at ideal temperatures (60-86F for pot), creates more food energy than respiration uses during light hours. At nighttime there is no photosynthesis, but the plant is still respiring, using the stored energy to keep growing and breathing. Photosynthesis and respiration rates do change with temperature, however, and are actually equal when temperatures get high enough(96F).
Maybe a higher temperature would be optimal for 24/0 light cycle, because all you are doing in lower temperatures is constantly storing energy when it can be used. I'm not sure if this is actually true, but it would definitely make sense. There has to be more things that are affected by higher temperature.
I would do an experiment on this....
Have an 18/6 set for 86F during day and 72F at night(this has proven to be optimal growth when temperatures are about 10-15 degrees below nighttime)
Have an 24/0 cycle with a temperature of 94F. (you don't want the temperature to be too close or the plant respiration rate might be larger than the photosynthetic rate and that's bad)
If you disagree please explain.
