The subject of lighting is a little more complicated as exactly how much you need depends on multiple factors. Nevertheless, the amount of light you provide your plants with and the quality of the lighting products you use will have a direct impact on the size, quality and potency of the buds your plants produce. In fact, second only to genetics it is lighting that will determine if and how successful you are.
In terms of lighting quality, it probably should not take a genius to figure out that a standard household light bulb really isn’t going to do the same job as a premium HPS rig that delivers the exact spectrum of light your plants require. When it comes to the amount of light you need to provide, this is something that will be determined by the size of the plants you are growing, the type of grow space, the number of plants present and the specific strain you have chosen to cultivate. Nevertheless, it is generally advisable to follow a ‘more is better’ mantra – just as long as you don’t take things too far and end up burning your buds prematurely.
