Recommend Auto light schedule?

Gang, do you have a recommendation for light schedule for an auto flower? Guess what im asking is if any of you think they need a dark period during any stage of growth and why. Growing all organic, supersoil under 300w LED.
All suggestionS/opinions appreciated.
Thanks.
 
So anyone want to opine why a dark period is needed or not needed ? Would like to hear your thoughts, especially if you have direct experience with autos. No trying to figure out a right or wrong dogma, just wanting to apply a best practice approach.
Thanks all.
 
Autos are crossed with a ruderalis to become auto flowering. Ruderalis originally grows where summer is extremely short but long, long days. Thus 20 to 24 hours of light is common practice. Hope that helps. Cheers
 
I do 18 / 6 n have done 24 also its what works best For u, everyone has thr own way on doing things what may work For u may not work For me , i had a lot of ups and downs when i started with autos i way only getting 1 or 2 Os a plant but i found what worked best For me now i get 4 Os or better a plant , iim no por but we all have different way of doing things cuz we all have diffrenent set ups ,, no one here is wrong its what works best For u , growers love from the heart
 
I use 18-6 for a couple of reasons.
First of all, the extra 6 hours of electricity every day of a grow may get you a little more weight, but I don't want to spend a lot on electricity to get a little bit of weed. Just not cost effective.
Secondly, leaves grow in daylight and roots primarily grow in the dark period. I consider the roots to be the most important part of the plant when it comes time to grow flowers.
Most of what you read in the growing community is about attempting to mimic nature, and it does get dark every day. If there is ever a day when it doesn't get dark, that will be the lead story on the news.

Not true in northern latitudes such as Alaska or parts of Russia where ruderalis is believed to have originated. Hence the auto factor.
 
I have photos in with my autos i need to change the lighting to 12/12 how will this effect the auto?
 
According to royal queen seeds They produce better plants on 18/6 over 20/4 or 24/0. At like a 99% rate (Per Yield). The article on there site says only 1 out of every auto grow theve ever grown did better on 24/0. With as many auto grows they've grown which I can imagine is a ton, I would trust their results.

I've never grown autos but read that during some research into them.

As long as they are flowering you should be fine. Trying to veg in less than 12 hours light will really stunt growth. You have to remember autos are all about how much light They can get to produce growth in a fast period. If they are not flowering I would wait to flip the switch.
