Many flowering plants are what are known as "diurnal" plants—they use the cycle between day and night to trigger their growth patterns. This is important to understand when growing plants indoors so that your crop management takes this cycle into account.
Deciding on what growing lights to use in your indoor garden is a major decision, with trickle-down effects not only on your potential harvest but the entire operational setup. Today, there are two main types of indoor grow lights to choose from, high-pressure sodium lights (HPS) or light emitting diodes lights (LED). The ongoing debate between the two very different lighting options is fierce with experts weighing in on both sides. But recently, as LED lighting companies continue to make improvements to their products, the tide is moving in their favor.
