Ok, if anyone can provide any insight to my theory would be great. Let's say hypothetically, I had a light fixture that provides 35 par and on for 12 hours and all plants are doing well in tank with no algae.

Would doubling the light intensity (70 par) and halving the photoperiod (6 hours) provide the same results? If not, what would most likely change?

Hopefully I didn't word the question too awkwardly. Lol

Some great conversation going on here.

I have thought about the extreme examples but that is the reason I provided the examples I did. Plants are already growing well, so light needs are already met, now we double intensity and half duration from 12 to 6 hours.

Also, assume coverage is same. So same light fixture and placement just different intensity and photoperiod.
