How many hours of light is required for long and short day lighting?

* The amount of lighting varies by plant type. However, a general rule would be more than 12 hours of darkness for short-day plants, less than 12 hours of darkness for long-day. while the above answer may work as a rule of thumb it is far from accurate. the term long-day or short-day is not a specific number of hours even if you are looking at the same plant variety or even the same plant itself. the term is relative. a shift to longer nights (resulting in shorter days) which happens in winter will signal to a short-day plant to bloom and the other way round for long-day plants. note i pointed out the lengthing or shortning of the dark period relative to the light period as the signal. zaf.

How long are the days and nights in January and in July?

In terms of daylight and darkness, that will depend on where in the world you are. If you are in the Antarctic, then it is bright all of the time, with no darkness, in January and completely dark with almost no light in July. It would be the reverse in the Arctic. If you were on the equator, it would be about 12 hours of light and 12 hours of darkness all year. Between the equator and the poles, the amount of darkness and daylight will vary, getting more extreme the closer to the poles you get.
