What light cycle for autoflowering

Titles say it all. I have a Black Widow autoflowering. Been using 16/8 LED light on it. Is this good? Suggestions?

Yes, since autoflower will flowrr when ever it wants to on its own then theirs no point in doing a schedule change, 18/6 is good. I myself am growing an autoflower also and I am doing 18/6. Some people to 20/4 and 24/0 but why waste electricity when it's been known 18/6 it's perfect also.

I run my auto under 24hrs of light. My cola's are so freaking fat that my plant just bends over. Its ridiculous bro....then I woke up. 18/6 in my opinion.
