Several types of hydroponic systems operate differently. Choosing the perfect fit can be challenging since different systems may be more suitable depending on your hydroponic gardening plans. For instance, growing plants for personal use may require different equipment and care than large-scale hydroponic farming. Therefore, it is vital to have a clear understanding of your plants and goals before selecting a hydroponic method. This article aims to break down the different types of systems available to help you find the best fit for your crops and budget.
You must create a suitable hydroponic system and maintain water purity for faster plant growth. There are six different hydroponic systems available for use, and they are listed below:
1. wick system
In a wick system, plants are grown in a medium such as perlite, coconut coir, or vermiculite. These plants rely on a wick to transport water and nutrients directly to their roots. They are easy to set up and operate, making them popular among beginners and small-space growers. They are ideal for growing herbs, lettuce, and other small plants, providing a cost-effective and space-efficient method of growing healthy crops indoors.
Benefits Of Wick System
- Affordable
- Easy to build
- Great for children or beginners
Disadvantages of Wick System
- Not suitable for larger plants or crops.
- It could be more efficient and wasteful of nutrients and water. In some cases,
- The system may overwater the growing medium, making it difficult for plant roots to absorb oxygen. Mistakes in wick placement can also lead to rapid plant death.
- The soil is constantly wet and humid; it becomes more vulnerable to fungal disease and root rot.
A wick system is best for small Plants & Herbs.
Benefits Of Deep Water Culture or DWC
- Easy to maintain
- Perfect choice for beginners
- It is compact and ideal for those with limited space.
Disadvantages Of Deep Water Culture or DWC
- It is not ideal for more extensive or long-growing cycle plants.
- If the air pump fails, the plants will die due to a lack of root oxygenation.
- The stem will rot if the plant is too low in water and will not get enough water and nutrients if it is too high.
2.Deep Water Culture or DWC
Hydroponic deep water culture (DWC) is a well-known hydroponic system where plant roots are submerged in a nutrient solution. In this system, an air stone is connected to an air pump at the bottom of the reservoir to provide oxygenation to the entire system. The bubbles from the air stone also help circulate the nutrient solution, providing the plant roots with ample oxygen, essential nutrients, and hydration, which promotes rapid growth. DWC systems offer an accessible entry point into the world of hydroponics and have proven to be a popular choice for interested growers. It is easy to assemble a deep water culture system at home or in a classroom without expensive hydroponics equipment.
DWC is best for small plants
3.Ebb & flow system
Ebb and Flow hydroponics is a popular growing method among hobbyists due to its simplicity, affordability, and ease of setup. This system floods a grow bed with a nutrient solution from a reservoir using a submersible pump equipped with a timer. The timer controls the duration of the flooding, after which gravity drains the water slowly out of the bed to flush it back into the reservoir. The system also has an overflow tube to prevent over-flooding and damaging the plants. Ebb and flow hydroponics supplies plants with abundant oxygen and nutrients, promoting rapid and vigorous growth. This system separately provides the perfect amount of nutrient-rich water and oxygen to the plant’s roots, ensuring optimal growth and health.
Ebb & flow is best for tomatoes, kale, cucumber, and lettuce.
Benefits Of Ebb and Flow Systems
- Efficient use of nutrient, water, and energy
- Ensures sufficient oxygenation of the roots
- Promotes healthy root development
Disadvantages Of Ebb and Flow Systems
- Require large quantities of growing medium
- Power failure or unfavorable environmental conditions can quickly dry out and kill the roots.
- To ensure success, maintain optimal growing conditions.
Benefits Of Drip System
- Quickly regulate the delivery of essential nutrients and water
- Setup and maintenance are affordable, so it’s a cost-effective solution
Disadvantages Of the Drip System
- Regular pH testing corrections are required.
4.Drip System.
This is the most popular hydroponic system.
A drip system is an active hydroponic system. The hydroponic system involves an aerated reservoir rich in nutrients and pumps a solution through a network of tubes to individual plants. The system takes nutrient-rich water and pushes it up to the grow area. Then, it slowly drips the water onto the plant’s roots, ensuring they remain moist and well-nourished. The drip system is prevalent in hydroponics as it works great for home and commercial growers. It can also support much larger plants than most other hydroponic systems, making it a preferred choice. A properly sized drip system can keep melons, pumpkins, onions, and zucchini. It holds more significant quantities of growing media than other systems and works best with slow-draining media like cocopeat and peat moss.
A drip system is best for vegetables, soft fruit, tree, and vine crops.
5.Nutrient Film Technique Systems
The nutrient film technique is often used to grow smaller and quick-growing plants. The Nutrient Film Technique (NFT) hydroponic system is a setup of tilted channels that allow water to run down the grow tray’s length and drain into a reservoir below. An air stone aerates the water in the reservoir, and a submersible pump pumps it back to the top of the channel, a recirculating hydroponics system. The system is suitable for cultivating different types of plants, including herbs, vegetables, and flowers, and effectively delivers nutrients and oxygen to the plants’ roots for optimal growth. One of the advantages of hydroponics is that they recirculate the water, which means they do not require large quantities of water or nutrients to function. NFT systems are ideal for large-scale and commercial projects.
NFT is best for leafy green plants with a short growth period
Benefits of Nutrient Film Technique
- A minimum growing medium is needed.
- Recirculating and water-saving
- Ample air exposure for oxygenation.
Disadvantages Of Nutrient Film Technique Systems
- The system is vulnerable to pump failure and power outages
- Not recommended for for growing large and heavy plants.
- It’s crucial to monitor the solution to ensure it’s being delivered correctly, as any malfunction of the pumps or timers can potentially damage the crop.
- when the roots grow unchecked, they can obstruct the nutrient channels, leading to further issues.
6.Aeroponic system
Aeroponics is a method of growing plants without soil, where the roots are suspended in the air and exposed to a nutrient-filled mist. This method promotes rapid growth and efficient nutrient absorption, making it a sustainable and space-saving option for agriculture. Aeroponics systems are enclosed structures, such as cubes or towers, that can hold multiple plants simultaneously. By providing essential nutrients directly to the roots, aeroponics can lead to higher yields and healthier plants, which has the potential to revolutionize modern farming practices and contribute to food security in an increasingly urbanized world. Additionally, aeroponics provides greater access to oxygen for the roots, resulting in healthier plants, faster crop growth rates, and increased yields. Aeroponics systems are highly efficient in water usage, using 95% less water to grow crops than irrigated fields.
Benefits Of Aeroponics
- The roots are more oxygenated.
- Better yield and growth rates.
- This system uses little to no growing medium.
Disadvantages Of Aeroponics
- Setting up this system can be expensive.
- It is essential to closely monitor the nutrient solution nozzles to prevent failure and ensure the roots do not dry out.
- Due to the complexity of this system, it is generally not recommended for beginners.Aeroponics is best for Lettuce, Mustard greens, Spinach, and similar crops.
