Kush is like other cannabis plants and will need an extreme amount of light, when planted outdoors they will need at least six hours of light and three hours of direct sunlight. The ganja grower that plants indoors will have cycles where there is light as long as twenty-four hours a day and then cycles where there is 11 to 13 hours a day to simulate the sun.
The lighting will ensure the crop grows to maturity, when there is not proper lighting it is impossible for the marijuana plants to grow to their fullest ability. This is important for the grower to have the correct amount of lighting if the plants are going to grow to maturity as large as they should. There is also the fact that if the marijuana plants are trying to reach lighting they are spending all their nutrients on them and this will affect the level of Kush THC.
