Probably an easy answer

so, my first grow is underway, just turned on flowering on my first plant (clone). I have an autoflowering femenized seedling growing and here’s my question. When I migrate my seedling (in a few weeks) into the grow tent, the lights will be on 12/12. Will this adversely affect the growing of an auto flower?

your autoflower will flower just the same but you will probably yield less then having the same light at 18/+ hours of light

They will grow fine but your yield will suffer.
