the reason for growing them indoors is some of us are not lucky enuff to be born into or live in a climate that promotes outdoor grow so for that reason they are IMO brilliant..
How are they brilliant? They don't grow any better indoors than photos. All they do is flower on their own. I grow mostly indoors myself as I don't live in a climate that allows growing many of the strains I like. I fail to see the logic behind what you're saying.
Put light on timer. Switch timer to 12/12 when you want to flower your photoperiod plant. It's that simple. You seem to misunderstand what an autoflower is. It's merely a day neutral plant that will flower regardless of light hours. That's done by incorporating the ruderalis subspecies into the genetics through breeding to obtain the autoflowering trait. Ruderalis is lower in THC but may contain higher levels of CBD. It doesn't have any added benefit other than the autoflowering trait which gives less control to the grower.
I'm not trying to slam autoflowers but they don't do anything more than flower on their own without the need to change light cycles. They are well suited for outdoor grows in climates that are not conducive for standard photoperiod plants. Exactly the opposite of what you think.
Unless you are growing them in a veg tent or have one tent and do staggered grows meaning plants of different ages all growing at the same time there really isn't a good reason to grow them indoors. I know people do but I'll never understand why.
As far as them being brilliant for indoor grows, they are not except for a couple reasons which I pointed out.
