Veg stage lighting duration

Some say that during the veg cycle it's enough to keep the light on for 18 hours. That means 18/6. Others keep the lights on 24/24. How do you keep your indoor plants? 18/6 or 24/24? Can this detail make a big difference?

They respirate during the dark hrs, I feel they need this break, at least a 4 hr break. Are their any studies that show bigger plants faster using 24 hr light vs 18 6? Like side by side clones compared? I feel like it's extra electricity for a stress plant. I'm gonna go do some reading

They also do a lot of growing in the dark.

It doesn't have to be 18/6 or 24/0
You can have anywhere in between.

I subscribe to a dark period, so if its winter 20/4
In summer 18/6

Same. I need a full clone side by side grow in veg 18 vs 24, then into flower to see if they r both healthy n what produces what before I can just leave my lights on 24 7

My mother's and clones are kept under 16-8 in the hopes they slow slightly in growth.

Exactly..

We need more tests with more cultivars.

It's all well and good witnessing how they respond in veg, but how does that translate to flower and the end result.

Agreed, and I can also see where it may be probable to expect an increase in things like hermaphrodite plants, throwing nanners, foxtailing, and other stress symptoms when going from a life of 24 hr light to 12 12
