Recently I read an article about lightings effect on plants based on strain differences, it might have been from rosenthal(sp?) but I dont remember I'll see if I can find it and post a link.What was said was that if indoor lighting was based on the plants region of origin better overall plants are possible. For example an equatorial sativa may actually do better with a 14/10 to 18/6 veg where a northern indica could want a 16/8 to 20/4 cycle also light angle was mention where an equtor sativa generally has sun high in the sky most of the time the northern indica has the suns arc gradually rise until mid summer then drop back towards the horizon. Now I know 18/6 or 20/4 produces quick growth but at what costs? In most living things growth rates outside of their genetic norms are know to cause an increase in health problems.What I'm thinking is that if you were able to have a light mover that not only moved the light linearly across the plants but also swung an arc from horizontal through a 180+- arc to horizontal to mimic sun motion at the plants approximate latitudinal home region what positves/negatives could be seen?Also would a gradual shift from veg to flower be of any benefit? IE: 18/6 to 16/8 to 14/10 to 12/12 over say a week or two? Just some random thoughts, at the moment I am not able to grow indoors but once I am( and have a decent stock of meds lol) I plan on doing experiments such as this. Your thoughts, ideas or comments...?
 
You solar sensor automatic moving full spectrum lights arnt cutting it? Try our Full auto Swiss Greenshouses !!! For real though read about that.

Post the link for this article some things just dont sound right at all. And its impossible to mimic the sun, and the sun dont swing it rotates on an axis.. If you turn your plants like you should be doing you should not have to turn your light into a trapeze act. If your not growing indoors are you growing outside? Playing with the light schedule like " IE: 18/6 to 16/8 to 14/10 to 12/12 " is most likely gonna give your plant light stress and you will start to produce seeds (well male plant parts to start with).

I've been searching for this article all day so I can make sure I have the right info, if and when I find it I will post a link, I'm pretty sure I found it through a post on RIU.The sun doesnt swing or rotate,technically, we do. What I was trying to get at is during the course of a day the sun "swings" from the horizon in the east to its high point in the sky back to the horizon in the west. Then over the course of,lets say spring to fall, it rises from closer to the southern horizon to a high point in the sky and back to the horizon in the south,get it? This example is based on my loc in NE USA. As far as adjusting the light schedule I would think a gradual change would have less stress than going from 20/4 one day to 12/12 the next. At the moment I'm done growing, well almost, gonna cut my outdoor plant Sat. This is just all hypothesis- I think way to much sometimes. Now I'm not talking about doing a 6-8 month grow but using this principle at an accelerated rate say over a 2-3 month period,we as growers try to mimic natural sun for our plants but the sun is neither stationary on just on/off(another thought I have about a dimable on/off cycle-another post for that lol). Idk the principal seems sound too me. I'm off to find that article,wish me luck...
 
Good luck, hopefully ya find it I like a good read :D I see what your trying to do though, it does seem like it can work. But the only real facts and proof you desire is getting it first hand. Start a journal up when you start this grow, I'd subscribe and follow. Would be interesting :D
 
The Farmer almanac is your friend.

yes that would cause light stress for indoor plants. But an outdoor strain using a GPS or Almanac to program lights might help some how.

The angles also determine how much atmosphere the light travels through, giving us the colors of the seasons and the harvest moon.

plants use moon light..mimic that too.
