A Brief History of Hydroponics

Learn More About Hydroponic Growing As a subset of hydroculture, hydroponics refers to growing various types of plants in an aquatic based environment or soil less medium using mineral nutrient solutions in feeding plants in water. With hydroponics, we are no longer limited by season or climate and we can grow virtually any plant at any time of the year. Modern horticultural LED lighting make up current hydroponic systems, allowing us to grow our favorite plants when and where we choose, and transforming our favorite hobby. Hydroponic gardening do not only involves nutrient film technique (NFT) wherein plant roots are suspended directly into water without any growing medium because there are several variations of NFT that many people are not yet aware of such as wicks system, water culture, ebb and flow system, and aeroponic system. The simplest type of hydroponic system is the wick system which is described as a passive system without any moving parts, and the nutrient solution is drawn up into the growing medium through a number of wicks. The water culture is an active system with movable parts, wherein the plant roots are totally immersed in the water that contains nutrient solutions. The ebb and flow system works through grow tray temporary flooding, wherein the nutrient solution from the reservoir surrounds the plant roots before it is drained back, with automated mechanism using a water pump on a timer. Aeroponic system is a type of high tech method of hydroponic gardening that uses air as the primary medium like NFT. The LED light bars are the best choice for indoor growers because of its coverage and utility. While it is true that LED lights are not easy to install in tight spaces, LED lights are more slender and longer. As you research online, you’ll find many brands of LED growing lights with high quality for healthier plants and a more productive harvesting. Most LED light bars are equipped with “heat sinks” which are manufactured with pieces of aluminum that are extruded to increase the light bar’s surface area, pulling heat from the plants’ face. As compared to HID or fluorescent lighting, LED light bars produce more light per watt, that is the reason they run cooler which reduce electricity costs as the well as risk of fire in your hydroponic grow room. Built-in fans are present in most LED grow light bars, not requiring extra ventilation except in special circumstances. With LED grow lights, they remain effective for many years, thus reducing the need to spend money on replacements.
