Monitoringclub.org | What is Hydroponics? Hydroponics is a method of growing plants without the use of soil, instead relying on a liquid growing medium and a nutrient-rich solution.
It has been claimed that vegetables grown using hydroponics have better quality compared to conventionally grown vegetables because they are fresher and free from pesticides and chemicals.
Hydroponic plants use a liquid growing medium and do not require soil. The method and location of planting are controlled, eliminating the need for pesticides to protect them from insect pests.
You can place hydroponic plants anywhere around your house or simply hang them on a wall. This makes hydroponic gardening a trend in urban farming or modern gardening in urban areas.
What is Hydroponics?
Common types of plants that use hydroponic systems are tomatoes, cucumbers, watercress, and chili peppers. The hydroponic system involves growing plants without soil, instead using water mixed with mineral solutions and other nutrients. Nutrients such as animal-derived fertilizers or chemical fertilizers like urea are commonly used in hydroponic plant cultivation.
Tomatoes, cucumbers, watercress, and chili peppers are some of the frequently grown plants using hydroponic systems. Hydroponic plants require less water compared to traditional soil-based planting methods.
The hydroponic technique has gained popularity due to its ease and efficiency in utilizing available space. You don’t need a large area; you can even set it up in a small room in your house.
Benefits of Hydroponics
This method has become increasingly popular among farmers and plant growers. Hydroponics is a method of growing plants without soil, instead using nutrient-rich water and other mediums such as sand, gravel, or other organic materials as a substitute. It offers several benefits:
Improves plant quality
Hydroponic farming allows farmers to control and provide precise nutrition to plants. Nutrients are directly exposed to the plant’s roots, resulting in healthier, faster-growing, and more productive plants.
Increases crop yields
In hydroponics, plants receive precise and consistent nutrition, leading to increased crop yields. Moreover, because plants are grown in a controlled environment with proper temperature, humidity, and pH, the risk of plant damage or loss can be reduced.
Hydroponic systems are highly efficient in water usage compared to traditional soil-based methods. Hydroponic plants only require about 10% of the water needed by plants in soil because the water in the system is continuously reused and doesn’t evaporate into the atmosphere.
Enhances local food availability
In hydroponics, plants can be grown indoors or in controlled environments, allowing year-round cultivation independent of seasons. This increases local food availability, reduces transportation costs, and minimizes the environmental impact of food product delivery.
Reduces pesticide use
With hydroponic plants grown in a controlled environment, the risk of pest attacks and diseases can be reduced. This means that farmers can decrease the use of harmful pesticides and herbicides, benefiting the environment and human health.
Improves air quality
Indoor hydroponic systems can improve air quality. Hydroponic plants absorb carbon dioxide and release oxygen, thereby enhancing indoor air quality.
Hydroponics is a method that can improve plant quality, increase crop yields, save water, enhance local food availability, reduce pesticide and herbicide use, and improve air quality. It is an attractive choice for farmers and plant growers seeking better and sustainable results.
Types of Hydroponic Systems
There are several methods for hydroponic cultivation. Here are some hydroponic methods that you can try at home:
This is one of the simplest and most beginner-friendly hydroponic systems. It consists of a growing container with a wick that draws nutrient-rich water from a reservoir to the plants’ roots. This passive system requires no pumps or electricity but may have limitations in terms of plant size and nutrient delivery.
Deep Water Culture (DWC):
The next type of hydroponics is the deep water culture system. This method is quite simple because the plants you are going to plant are simply placed in aerated water. This method is one of the simplest and most popular hydroponic methods used by many people. Many think that this method is the easiest type of hydroponics to do.
Nutrient Film Technique (NFT)
This system involves a shallow, sloping trough where a thin film of nutrient solution continuously flows over the plant roots. The excess solution is collected and recirculated to maintain a continuous flow. NFT is suitable for growing small, lightweight plants such as lettuce and herbs.
Drip hydroponics involves using a timer-controlled pump to deliver a nutrient solution to the plants through a network of drip lines or emitters. The solution is dripped onto the growing medium or directly onto the roots. This system offers flexibility and can be used for a wide range of plants.
Ebb and Flow (Flood and Drain)
In this system, plants are placed in trays or pots filled with a growing medium. Periodically, a nutrient solution floods the tray, submerging the roots, and then drains back into a reservoir. This cycle repeats at regular intervals, providing oxygen and nutrients to the plants. Ebb and Flow systems are versatile and suitable for various plant types.
Aeroponic systems mist the plant roots with a nutrient-rich solution suspended in the air. The roots receive nutrients and oxygen directly, promoting rapid growth. This method requires specialized equipment and precise control of environmental conditions but can yield high crop densities and fast growth rates.
These are just a few examples of hydroponic systems available. Each system has its advantages and considerations, so it’s essential to choose one that suits your specific needs, available space, and resources.
