What light cycle you run for Auto Flower plants? Do you just run 12/12 from start? Do you run 24hr light?
Autos never need to be switched to 12/12. You can run any cycle you choose. Most common are 18/6, 20/4, or 24/0. Benefits of one over the other are debatable, try them all.
is the type of light important to an auto? - is MH better than HPS to run, or can you mix that up too?
20/4 and you want hps for flower just like with photos..you can run mh the first few weeks if you want
