how long should I keep my lighting on to prevent grow rest? (that ís something I want to prevent, right??)
Sue is correct; I would also suggest leaving the lights on for 14-24 hours each day. You would want the plants to grow as much as possible. Some will take a rest even if the lights are on for a long day-short night (16 hours on 8 hours off). However, they will start to grow again without any change in conditions when they are ready.
