Re: 24 hr light cycle???
For veg, I've done 24/0 before without issue but switched to 18/6 or 20/4 because I think plants benefit from a little rest period.
If you want to increase growth rate, I read that 6/6 is the way to go, havent tried yet but plan on it next cycle.
Now I am assuming you are referring to 24/0 veg timing and not martian method flowering when you say leaving lights on 24... ?

I used to think 24/0 was the way to go for veg but have since changed my thinking.
I dont think the plants benefit that much from the extra light compared to say 20/4 or even 18/6 and I think I read that the roots grow more in the dark. I think we all know more root growth equals more top growth.
As I mentioned above, I've read that running lights at 6on/6off/6on/6off for 24 will speed up growth cycle and apparently produce tight internodes. I'm curious to try that and will probably due so next veg run.
Switching your current lighting schedule to 24/0 will be fine but I'm not so sure you will be doing the right thing for the plants. Another consideration is that if you are using a lot of wattage to veg, then an extra 6 hours a day will bump up your power usage 25%...

they say you get 30% more faster growth 24/0. the plant dosent need a rest period in veg it still can do everything it needs to do with the lights on.

A light cycle of 6/6/6/6 would do NO benefit to your plants. It might make sense in theory but in reality the short periods of both light and dark would stress the plant enough to hermie.
Im running mine 24/0 now...
i did a test a while ago. with 18/6 and 24/0. the 24/0 was allot faster growth.
plants that grow under 24/0 flourish and do not need a quantity of darkness in order to rest and perform Photosynthesis properly. more nodes are formed, more branches are created, leaf numbers increase, and the plant is growing at its finest.
The 18/6 photoperiod expels 3/4 the amount of light that a 24/0 photoperiod dose.
there are no problems associated with 24/0 and although some have attributed cannabis sexual dysfunction (the hermaphrodite condition) to 18/6 photoperiod, these problems are actually the result of heat stress.
a 24/0 photoperiod requires that your grow room temperature be kept well-monitored.
the 18/6 is cheaper to run and you use a 1/4 less electricity and extends the bulb life also.
i still use 24/0 no matter what because the growth cant be beaten. but theres facts about both ways for you.

Wouldn't that be the equivalent to a flower cycle? The plants would be recieving 12 hours of light and twelve hours of dark.
Sounds pretty sketchy to me.

Not only sketchy, but also very stressful on the plants.
what he said
The 6hr on off light cycle would keep the in veg but it would stretch and look pale and spindly it whole life.
I ran tests on photocycles some time back and my conclusions were that the 24hr plants did grow a bit faster and had a hi yield. The 18 on 6 off plants were not as tall but were more lush with a slightly higher yield because of the meatier buds. Rooting clones dont seem to care one way or the other but they have a better/quicker bounce back from the shock with the dark period.
The other reason I stick with the 18 hr period is energy savings and giving everything a rest like ballasts, blowers etc.

I'm running 24/0 also I think it works great.
My plants all grew very fast and I am growing 3 different strains...
I believe thats the benefits of growing indoors more lights!
Cannabis doesn't need to rest in the veg stage she will...

Mine went on 24/0 as soon as the seeds hit the dirt. It worked well for my grow. Plan to do the same for round two.
Only difference I know of is that on 24/0 the plants tend to be shorter, bushier w/tighter internodes. But otherwise it's pretty much your preference, since you're payin the bill. Either will work. My current ladies were on 20/4 during veg, and the difference was marginal. Blah 
I use 24/0 but have used 20/0 18/6 and 16/8.
And the only difference i've noticed is that with the less light you give the plant the loner the internodes will become!
I now grow 24/0
And the whoever started the myth that roots grow in the dark is ridicules, if thats so how come my vegged plants and clones that are kept under 24/0 lighting explode with roots.
Go with what ever you can afford!

here a old post but it explains the biological different
Not sure how true it is but sounds about right
After reading this I want to try a 18/6 next to a 24/0 to check the potency since according to this reading 18/6 is more potent...
