For commercial cultivation facilities, labor-saving techniques are important. As the number of plants in a garden increases, the amount of effort it takes to care for all of them increases as well. One of the most labor-intensive practices that can easily be eliminated is raising lights as plants grow.
Many growers advocate the use of an 18/6 light schedule (18 hours on, 6 hours off) while plants are in Veg. However, this may not be the most beneficial light schedule. Switching to a series of 6/2 (6 hours on, 2 hours off) light patterns may increase plant growth while also potentially creating a more stable controlled environment.
