Autoflower light schedule question

Hey everybody! I hope someone can riddle me this as I have found no credible information so far on the topic. I've grown auto's with a regular light schedule of 20/4 and I know how they operate with that "climate" setting, but this time is a little different. I have a sweet tooth, regular photo-dependent strain going that I just put into flowering and I started an auto thinking I could outdoor grow it, but I can't. So if I were to put the auto in with the regular one while it's on flowering, will it still mature to full flowering on 12/12? Thanks for your future input guys.

You cant stop the autoflower. It will flower no matter what light period, but the growth and maturity of the buds will depend on how much light. You can grow a 12/12 autoflower I wouldnt expect it to be as nice as the 20/4 af. I do mine on 24/0 and I love it so far. Mass growth.
