To answer your original question, no, it is not good to run your
lights 24 hours a day. All plants need a period of R&R, and most also require a cooldown. It is preferable to have a 10 degree drop in temp during the nite/lights off period.
During vegetative stage: lites on 16-19 hours per day.
During flowering/fruiting: lites on 12-14 hours per day.
Hope this helps!
