What technology is used in vertical farming?

Vertical farming is a revolutionary agricultural practice that utilizes innovative technologies to grow crops indoors in vertically stacked layers. This method has emerged as a sustainable solution to address food security challenges, particularly in urban areas with limited arable land. But what are the technologies that make vertical farming possible? Let’s dive in.

1. Hydroponics: Water-Based Growing Systems

Hydroponics is one of the core technologies used in vertical farming. It allows plants to grow without soil by delivering nutrients directly to their roots through a water-based solution.

• How it Works: Plants are suspended in water, where their roots absorb nutrients and oxygen.
• Advantages:
• Uses up to 90% less water compared to traditional farming.
• Reduces the need for harmful pesticides and fertilizers.

2. Aeroponics: Mist-Based Growing Systems

Aeroponics takes farming innovation a step further by using mist to deliver nutrients and water to plants.

• How it Works: Plant roots are suspended in the air and misted with a nutrient-rich solution.
• Advantages:
• Uses 95% less water than soil-based methods.
• Promotes faster plant growth and higher yields.

3. Aquaponics: Combining Fish Farming with Plant Growth

Aquaponics combines aquaculture (raising fish) with hydroponics to create a symbiotic ecosystem.
