Not sure if theres any benefit to it, but my controller has this function and I’ve been using it, I can say this round of plants look much better than the last.
But i cant say if it’s due to the new light or few additions to my feed that did that?
I believe anyway you can mimic mother nature, is a plus in my books!
Edit: as beacher said, the drastic swing from dark to light can be an issue as humidity changes with the fast change of light cycle. Vpd is an important thing to consider. But like I said mimicking mother nature is always a good thing.
