A few articles ago, I explored the pros and cons of hydroponics versus soil. The takeaway was that these kind of nurseries are fit for small plants. Many fruits and vegetables are small plants, some of which are vine plants, which will not take up much vertical space. When it comes to bigger plants, like trees, a bigger facility will be required to deliver a controlled system of fostering growth. We have explored the ideas of hydroponics and aquaponics but new urban ideas are trending. One such idea is aeroponics. Another is reusing shipping containers to create a nursery for these small plants, where UV light is delivered to the plants for 24 hours. Let's begin with aeroponics. Aeroponics is an innovative method of growing plants that eliminates the need for soil or an aggregate medium. Instead, plants are suspended in the air, allowing their roots to dangle freely. This is referred to as vertical farming . These roots are periodically misted with a nutrient-rich solution, ensurin...
