Creating a vertical farm is relatively easy. Simply place crops vertically above each other in a closed and controlled environment. By controlling the variations in temperature, light, humidity, and gases to make produce, farmers can increase produce while reducing resources and costs from traditional farming.
Most vertical farms use either:
- Hydroponics – where fruits, vegetables, and herbs are grown with nutrient-filled water
- Aeroponics – where produce is sprayed with water and nutrients systematically. Any unused water could be recycled and reused to grow the crops.
- Aquaponics – where water waste from fish is used to supply nutrients to plants and in turn purifies the water.
Just like traditional farms, vertical farms need lighting as well. However, instead of natural sunlight, artificial grow lights are used to maintain the perfect light level to grow produce. Rotating beds are also commonplace to optimise lighting efficiency.
