The goal of lighting indoor vegetable gardens is to adequately address the plant's required photosynthesis needs. Shop lights and common light bulbs are not the most effective choice as you cannot consistently broadcast the appropriate light output as the plants require. I prefer “LED GROW LAMPS” for all of my indoor gardens as they use reduced electricity. LED lamps to come in low-output and high-output types. Because they have less heat and produce more light, LED lamps can be used without fear of burning your plants.
