DLI is the key... it may be beneficial to give more hours of light with a weaker light... don't do this blindly.. and do observe and react to plant. the math only gets you in the ballpark and you'll have to trial and error the finer resolution. this is relative to temp, RH% and atmospheric CO2, so it can be a different "max dli" at any given moment. As long as plant remains healthy, keep slowly amping up , if you think it can handle more. (35-40DLI in ambient // 50-55DLI in a tightly controlled environment are good ballparks to start) Google for a DLI table.. it is directly 1:1 proportional to hours of use, so you can do some easy math to fill in blanks of table if needed. all of that said, still better for the plant to have some period of darkness. In some cases it may be better to go 24/7 but most likely only with a weak light relative to area of coverage.

I use 18/6 from seed to harvest on Autos i Think 24 hours light is waste of money

I have a 20-4 cycle. Fits so far. It's a little more than most, but I can't say yet if it'll really do anything.

Most auto growers use 18/6 but I happen to use 24/7 on all my autos (and I only grow autos) ... that might be changing now that the weather is warming up but we'll see. I use 24/7 simply because I couldn't keep the temps up in my tent during the winter and since autos don't actually need rest periods the way photos do, it was a win/win for me. You do what is right for you BUT do not provide them with anything less than 18/6! Best of luck with your grow!

Hey Growmie, Some people do try 24 hours light with autos but they use it for the whole grow cycle, not just germination. The average auto grower will use 18/6, it gives the plant time to rest and it saves on the electric bill. Feel free to shoot me a holler if you ever need any help, I'd be honored to assist you. Hopefully, this was helpful, and remember ... "Happy Growing" and "Free your mind one puff at a time".
