Seed companies loves autos because you can't take cuttings and there is a limit to how big they grow in general.
You could pull a few crops outside in a short time(only advantage)vs photos.
Nobody needs to grow auto's indoors, I can't see any advantage, it's not for the new grower and it's definitely not for experienced grower, they want control and often keep the best plant from a pack of seeds(clones)
You can't have control when you grow auto's, it's pot luck when each plant starts to flower.
Even if you want to grow a few different strains at the same time, you take the time to train the plants so you have a few bushy plants, veg time should never be rushed as it could make the difference of pulling 2 or 6 oz's per plant, depending on the space available but the veg time might only be 7-10 days longer for double the crop size.
