does the plant not need any hours of darkness

Would you like to go all day without some rest?

It will survive through veg and all, and might look good. But I personally Highly recommend you letting your plants sleep for like 6 hours lol.

no, except when your flowering, unless they're autoflowereing like Lowryder.

I always veg 24/0 right up to flower. I think they like the consistancy and flower sooner when given 12/12.
Had a guy tell me once that it would not produce roots if not given darkness. lol. I repot right before flowering and the pot is always full.

I've read experiments where they've tested how much light a plant can use in a day for photosynthisis and anything past 18 and the plant just doesn't do anything more. I don't think it hurts them but they just don't use all the extra light for photosynthisis. So your just paying for extra electricity.

thanx for da help im relived now

I agree. While the plant does not absolutely need the darkness, I've always noticed that the plants get a nice little growth spurt during the dark period. I've tried 24 hour light and it works fine, but I notice more new growth after the lights go off for awhile. All things need rest.
