I do 20/4 for veg room and 24 for clone/germination room.

what results do you get with 20/4 veg

Plants can only absorb a certain amount of light each day. I'd say however many light hours that takes that is what I would run. I do 18/6 personally and believe plants need some dark time. Ymmv.

I do 12/12 gas lantern from seed in veg. They won't grow faster with more light. It's always a balance act of what stage of growth you're in and what the plants are able to tolerate.

I've only seen positive changes going from 18/6 and will never go back!

Cheers!

I do 4 to 7 hours of darkness depending on the dimming options/minimum distance of light.

Its always about DLI (daily light intake) which I don't compromise, ever. Meeting the climate standards for it (temp/humidity - VPD)

For seedlings 24/0, DLI <15.
For vegetative state 20/4 - 17/7, DLI 20-40.
For flowering 12/12, DLI 25-40, up to 65 with co2.
