The answer to your dilemma is in your post "autoflower". Autoflowers are neat and can produce great smoke, but if you're seeking better control of yield photoperiods are your friend.
You should add a link to your sig so with every post peeps can check out your grow thread if they want.
Auto's do eliminate nearly every benefit of growing indoors.
Autoflowers have their place but for indoors I'm going to stick to photos. Up north here I wanted good autos for growing outside with minimal inputs and to have something finish before the weather turns too cold. Photos won't start flowering until the middle of August and we always had frost by the end of Aug or early in Sept. This last fall went on until mid Oct before we got a killer frost. Thanks global warming!
