California Light Works has an option to ramp up and down at the beginning and end of the light cycle on their Solar System controller. I use far red light (720-740nm) 5 minutes before and after lights out to trigger flowering and shorten harvest times.

if you want to shorten harvest time you can change 12/12 to 13/11

Do you mean the benefit of ramping up and down at sunrise and sunset. As far as I know it has never been shown to cause any affect either way. I think CLW added the feature Just because they could.

I had the same thought years ago, someone did release a moving light that changed light frequency etc I can't remember the name

my point is, in the fkn nature, the sun doesnt just appear and disappear, it comes gradually... i was curious if anyone tried this and if yes, does it have any benefit...lol

Since the sun dwarfs any artificial lighting the plants can get indoors, I can't see any benefit to further reducing the output of an indoor light to try to mimic the sun coming over the horizon.

You can do this really easily with LEDs. Mycodo is a great control software for the rpi that has the ability to implement this.

Have I done it? No.
Why? The light in my tent doesn't compare to what you see outdoors. So you wouldn't be hitting DLI for the plants.
Am I interested? Yes, I wanted to do this to start but decided to forget it when dialing in my tent. I may try it in the future since it would be easy for my LEDs. I have a theory it will make the plants healthier because it mimics a more natural environment.

Side note: I am working on a fish tank that will change light levels over the day. Can't wait to see the results.

yeah man, deff let me know when you start the project. i kind of got interested when im looking at the plants growing outdoors, they kind of start preparing for the night, getting their leaves down gradually. maybe as you said, they will grow healthier... who knows
