@MangoDudu,
Actually I initially started out with 18/6, then went to 20/4, now I'm at 24. I noticed the first 4 weeks the roots grow faster with a dark period. But after the first 4 weeks a plant under 24 light will out grow that plant both above and below ground. After about 4 weeks the 24 hour plant roots blow past a plant under 18/6. That's just from my personal growing experience. I notice my plants only rest for about 2-3 hours and go right back to being perky the rest of the day. Also I should tell you I sleep 3 feet away from my tent and leave it wide open so we live in the same exact environment and lighting. I love growing and I'm obsessed about it and my plants. They live EXACTLY like I do, but they don't have to go to work lol.
