How you set up your grow lights will have a direct effect on how well or poor your plants respond. Lighting is considered to be one of the most important aspects to growing indoor plants successfully. If the lights are not chosen carefully, they will have different effects on your plant yields.
If the grow lights are not strong enough to provide the necessary amount of light, or are too far away from the plants, your plants will not grow and reach maturity as fast. The plants can actually look stunted because they are not getting the amount of light they actually require for healthy growth.
