Q How high should I hang these grow lights from the tops of my plants?
AThe answer depends on several factors. First, your wattage of the light, higher wattage lights put out more heat. Therefore, you should hang them so your plants don’t burn. For example, 1000 watts should not be any closer than 2 feet from the tops of the plants. Another factor is how large the coverage area is, if you need a larger grow area then you should raise the light. Doing this will increase the coverage area, but decrease the intensity of the light. The last factor is what type of plants you are growing; if it is a plant that require more intense light than you will want to keep the lights lower. The chart below should help you get started.
