This efficiency can be further improved with aeroponics, a variant of hydroponics that uses only 5.3 U.S. gallons for the same yield.
Hydroponic farming also lead to higher biomass and protein production compared to traditional soil-based cultivation. These advantages, coupled with the impending threat of climate change affecting agricultural yields, position hydroponics as a viable solution for growing plant-based food, even in arid regions with limited water resources. Hydroponics isn’t confined to Earth; it has also proven its efficacy in plant production experiments conducted in space.
Types of Hydroponics
Hydroponic systems come in various forms, each with its unique features and benefits. The most common types:
| Types | Description |
|---|---|
| 1. Deep Water Culture (DWC) | This system suspends plants in a nutrient-rich water solution, providing them with the essential nutrients they need for growth. |
| 2. Ebb and Flow | Also known as flood and drain hydroponics, this system periodically floods the plants with a nutrient solution and then drains it away, ensuring optimal nutrient absorption. |
| 3. Nutrient Film Technique (NFT) | In this system, a thin film of nutrient solution flows over the plant roots, delivering nutrients effectively. |
| 4. Aeroponics | Aeroponics suspends plant roots in the air and utilizes a mist or spray to deliver nutrients, allowing for excellent oxygenation. |
| 5. Wick System | The simplest of all, the wick system employs a wick to draw nutrient solution from a reservoir to the plant roots. |
| 6. Drip System | This system drips nutrient solution onto the plants, either directly onto the roots or onto a supporting growing medium. |
