I came across this technique, and I didn’t find anyone saying that this technique really works. Lighting schedule is as follows 12 hours lights on, 5.5 lights off, 1-hour lights on, 5.5 lights off, and repeat schedule. The 1 hour on in between off period fools the plants that stay in vegetative growth state! Your immediate savings are 5 hours in energy costs daily, as well as your bulbs and equipment lasting longer.
I never saw someone doing this on a commercial level, if this really works, why commercial operations are not doing this?
This is the thread that I saw talking about this method thread
