I’ve run autos all 3 ways. 24 hour just sucked the wallet. I didn’t notice any benefits. 12/12 just slows them down lower yield. I even tried 20/4 they did ok.

18/6 for me is the sweet spot. Good genetics makes a difference. Training lst, gives ya good yields. On average I’ll pull 6oz+. I run dwc

Autos don’t require a change in the light cycle. No 12/12.

I run alot of autos 18/6. Yea I’d do your veg light first then about 4-5 weeks in switch to your flower light. 420 fast bud is the boss
