Is there a value of sunrise and sunset in indoor?

I use this feature as well. I definitely think it has a benefit, my plants are happier and my biggest yields from that cabinet were using the sunrise/sunset functionality.

Moving forward a couple years, do you still have the same opinion?

I ordered the adapter to allow my AC Infinity 69 controller to control my SpiderFarm SF4000.
What length of time to ramp up/down?
