Is it ok to switch from 18 hours of light to 24 hours light freely? Will it stress the plants out?
24 Hour Veg?

Why do you want to go from 18 to 24?
With my grows, I do about the first 4-6 weeks of veg with 24, then I phase the plants into 12/12 over a 2-4 week period(2 hours at a time).
It more closely resembles seasonal changes, saves electricity over 24 hour cycle, and greatly reduces the stretch you normally see going into flowering with a hard 24 -->12/12 cycle.
Using this method of light cycle switch my indica plants hardly stretch at all, and my sativa girls only put on 6-10 inches.

The expert growers I follow say that 20/4 is the optimum cycle. During lights off there is a bunch of things going on under the soil.
With that said, going 24/0 won't hurt your plants, but it won't help them either. Last winter I ran mine 24/0 to keep my grow room temps above 60 degrees.

I've run on a 24/0 cycle before. It worked out pretty well for me. But i've never switched from 18/6 to 24/0. It shouldn't hurt them though, I wouldn't see much issue.
As the gentlemen above me put it, 20/4 would be more ideal. Some dark time is good for a plant. It's rare, maybe impossible that nature would allow 24 hours of light.
And if you only add 2 hours to her light cycle, she pretty much won't notice the difference.
If I were you, i'd go 20/4.

24/0 = lots of root growth. Hardly any stretch.
18/6 = more stretch. Basic root growth.
12/12 = VERY MINIMAL root growth. ALL stretch. Min 3foot plants.. usually.

I agree. i still like 20/4 for veg.
