Lighting schedule // Need Help
I have been learning artificial lighting for plants and have already studied couple things.
I know what is PAR, advantages and disadvantages of the various lamps, necessary fixtures and etc.
Also I have learned how much light is needed for each plant from this article (http://www.extension.purdue.edu/extmedia/HO/HO-238-W.pdf).
But one questions is still unresolved: how to make a lighting schedule. For example: light day in my region in winter is 8 hours and my plants need extra 8 hours artificial lighting. questions is when i should switch on and switch off the light for better growth and yield.
I will be very grateful if someone give me a piece advice on my problem.
Also it will be very helpful to give some literature and articles about lighting.
Thank you and sorry for my english !
