What Is Vertical Farming?
Vertical farming is a method of growing crops in stacked layers, often within specially constructed indoor environments. Unlike conventional agriculture, it replaces soil with hydroponics or aeroponics and uses artificial lighting, precise climate control, and advanced monitoring systems to optimize plant growth. This approach drastically reduces land use and can produce crops in locations previously unsuitable for farming, such as urban centers or regions with harsh climates.
- Maximizes output per square meter by stacking crops vertically.
- Employs hydroponic (water-based) or aeroponic (air/mist-based) systems for nutrient delivery.
- Relies on LED lighting instead of natural sunlight, ensuring consistent crop cycles year-round.
- Utilizes computer-controlled environments to maintain optimal temperature, humidity, and CO₂ levels.
- Reduces the need for pesticides and drastically cuts water consumption compared to traditional farming.
