Vertical farming is the practice of growing crops using soilless farming techniques such as hydroponics, aquaponics, and aeroponics in vertically stacked layers. It often incorporates controlled-environment agriculture, which aims to optimise plant growth with nutrients, lighting and pH. Vertical farming is perfect for high density living areas or to save space.
Hydroponics is simply described as growing plants without soil. Hydroponics allows you to control more of the variables including pH levels, lighting and nutrients for optimal plant growth and produce yields. Water is the main method of delivering the nutrients to the plant’s roots, combined with growing media to help support the plant. Hydroponically grown plants dip their roots directly into nutrient-rich solutions, so plants get more of what they need much faster and easier. Hydroponic farming can be used in locations where soil conditions are too poor to support farming, or where space is limited. It can be done anytime and anywhere!
