My first auto grow was done 12/12. For security reasons. I didn't realise how much 12/12 would affect them. They took forever. I chopped after 16 weeks and they could have gone a few more weeks. They yielded well enough. The 3 autos weighed in at 297g and there was room for 4. 315w cmh.
Next time, same strain, smaller pot, 2L Pepsi Challenge, was 24/0. 315w cmh vegging lamp. Was a bit further on than the 1st grow when I chopped at 12 weeks.
If you want maximum yield psf per year, then 24/0. 12/12 for 16 weeks used less leccy. The sweet spot will be a balance between how long you can wait and how much leccy you want to use.
