autos vs clones

I’ve been growing for a bit indoors now and want to step it up. I’m currently running a 2x2 and a 4x4. I plan on getting another tent soon and switching to just clones and autos to keep a quick perpetual grow. My question is what is most efficient time and yield wise?

Clones.

Definitely clones. I ran a perpetual
SOG with clones for 10+ years. Small mother plants produced plenty of clones to put 10-12 plants into flower every 2-3 weeks. I constantly had 45ish plants flowering under an air cooled 1k hps in a 4x4 flood tray. The plants were in 6inch square pots of hydroton, and averaged around 20g dried per plant with mixed genetics, and about 30g each when mono cropping higher yielding genetics.
