You'll be just fine, Rondog. Although some people do run 24/0 photoperiod, I woouldn't recommend it. The plant's have developed over umpteen thousand years to sleep at night, I just don't see taking that away doing much good. When your in veg, as far as light cycle goes, the main thing to remember is that it's the hours of DARK that determine when a plant flowers, not the hours of light. When the plant undergoes ~12 hour dark cycles on a regular basis, it takes that as the que to start budding. Although it's worth noting that some strains (generally Sativa Genetics) will grow with as little as 8 hours of darkness, which is why we go with 18/6 for veg. Some people like to run 20/4 to be safe, but that's about the max I feel comfortable recommending. I know i'd be unhappy if someone prevented me from sleeping every night, I feel like the plants would probably feel similar.
While we're on the subject of Photoperiod, you should know that when you get to flowering aka switch to 12/12, that it's VERY important not to interrupt the DARK cycle with any light. Check for light leaks before flowering your plants too. those two things tend to cause hermies alot of the time. Some strains are more sensitive than others, but it's best not to take the chance. Do you know what a hermie/Male flower looks like? if not, google it so you have an idea of what to look for, alot of people say male flowers look like tiny green bananas.
