Ambient Light and Co2
Only time I have had to change it earlier is middle of summer here when sun comes up at 4 am lots of light but still not direct on the tank and I would get bba if it wasn't on early enough. I see my plants build up bubbles under the leaves in the morning before lights on just because ambient and my under 5 par moon light.
