I don't believe it matters in veg. Some feel plants need "sleep" like any other living thing. That sounds common sense, but I don't recall proponents having studies to support that belief.
When the plant is in darkness a hormone accumulates which is responsible for the plant to transform into a fruiting state. When it's in light, that hormone dissipates. The downside to light during the dark period (when flowering) is that it could cause the plant to not have enough of that hormone to flower.
But, in veg, you don't care about that. I veg plants in an open tent. I try to keep the ambient light subdued. Like twilight or dusk. Not absolute darkness.

24/0 for veg. some will argue 18/6 is better and that the plants need to rest. not true. MJ is one of the few plants that can photosynthesize 24/7.
and when you do go to 12/12, it has to be absolutely dark. watch out for small LEDs on power strips, etc. it will mess up your flowering.

If someone subscribes to the "I can do better than nature" philosophy (keeping lights on 24 hours to maximize growth relative to time), I'd advise them to look into LED "flower initiators." Hitting plants with 720nm (far red, I forget if it's 720 or 730) puts them into the hormone-producing state faster, allowing you to run something like 14 hours on in flower. More light, more growth, or faster finish.
I'm happy with the results of 18/6 and 12/12. Haven't been tempted to use more electricity to see what I get. I tend to gravitate toward how to use less.

not to nitpick, but 18/6 is not what happens in nature either. summer solstice in most parts of the US is at most 15hrs daylight.
what's the difference if you veg 3 weeks at 24/0 or 4 weeks at 18/6 electricity wise?

Light leaks are not a problem while vegging because our plants thrive without any darkness for vegging. I run my veg room at either 20/4 or 24/0. The more light veggers get the better they veg. We cut the lights from veg mode to 12/12 to encourage the plant to flower. By cutting the hours of light we hope to fool the plant into thinking it is Fall and therefore the plat should flower as she would in the wild when days get shorter. It is the difference in light hours that is important. Not the totality of darkness during flowering. In other words it is not fatal for there to be a bit of light leakage during flowering. Hope that helps shed light on the question...
Good luck, BigSteve.

so many questions so little time

Any light leaks at any time can induce a herm, many strains(phenos) are getting weak as generations pass by, I do worry for our future with many strains for this reason, any any stress on your part will turn a plant herm, stay sharp
