If you want quick indoor weed then do a regular plant 12/12 light hours from seed. Check it out in the advanced search feature.
Autos, in my opinion, are only superior to regular strains if you plan on growing outdoors, somewhere where it gets cold and wet too quick in the year, or if you want to pull multiple harvests throughout the year.
With autos, you can create your own seeds indoors in the winter, using colloidal silver to make your own femenized seeds of strains of your choice, and then use these seeds during the summer months.
If you only plan on growing indoors, i would recommend 12/12 from seed because the yeilds are very similar, the quality can be much better, and the light usage is as much as half of what autos need to produce well.
If you have an seperate indoor veg tent, you can flower autos in there
while your regular strains are vegging.
There are some very strong autos, so the choice is yours!
