Horticulture is the art and science of plant and crop cultivation. Healthy plants require the care of informed growers. For all applications, quality of light, the costs to purchase, install and operate LEDs are usually the most important factors when considering whether to invest in this technology. Therefore, growers and entrepreneurs are encouraged to perform a thorough economic analysis, such as determining the return on investment or internal rate of return. It is vital to be sure all of the inputs (for example, hours of operation per year, electricity price) are appropriate for your operation. Grow life with lighting.
