What is hydroponic farming? Controlled environment agriculture (also known as weather and climate-proof farming, or more commonly indoor vertical farming), is the production of plants in an indoor environment. While indoor farming is not a new phenomenon (greenhouses have been used for centuries), the more recent innovation of hydroponic farming breaks down the growing process even further by eliminating all unnecessary components of traditional farming. Thinking back to the process of photosynthesis learned in middle-school biology class, we can recall the core elements to plant growth as energy, nutrients, water and CO2. Controlled environment agriculture (CEA) follows this basic formula and does away with all unnecessary inputs that have become essential to our current agriculture system, such soil and pesticides. In the CEA process, conventional elements of traditional farming are substituted with artificial ones. Rather than from the sun, plants receive energy from LED light...
