Electricity is the hidden cost people forget when comparing autos with photoperiods, and the numbers favour autos less than the short cycle suggests. Twenty hours a day for ten weeks adds up to more lamp hours than a photoperiod run of four weeks veg and eight weeks at twelve. A worked example using a one hundred watt board and average tariffs is on https://turboautoflowerseeds.com and the auto came out a little cheaper per gram only because it finished sooner. Dropping to eighteen hours closes most of the gap.
