Hydroponics is a new, eco-friendly technique for farming plants without soil, providing essential nutrients through water. This innovative method of gardening is quickly gaining popularity as it proves more effective than traditional soil-based planting, enhancing the growth rate and productivity of crops. There are various types of hydroponic systems available, suitable for growing herbs, vegetables, and flowers, making it an excellent choice for both indoor and outdoor gardening.
Hydroponics farming is a broad category of systems which are many categorized depending on the type of plant, space and resource use. We can differentiate between basic methods such as wick systems and more complex ones like aeroponics and this is why knowing the differences between these systems is crucial when choosing a system for a garden. Some of them are based on the nutrient delivery by diffusion only and some of them have pumps and timers to control the environment for the plant.
In this guide, we’ll explore six popular types of hydroponic systems: There are several hydroponic systems including; wick system, deep water culture (DWC), nutrient film technique (NFT), ebb and flow, drip system and aeroponics. Both systems have their advantages and disadvantages, knowing how they function will allow you to determine which one will suit your gardening needs.
Here is the Different Types of Hydroponic Systems Explained
1. Wick System
The wick system is the easiest of all hydroponic systems to set up and is therefore recommended for amateurs. It is a passive system, which means that it does not have pumps and other equipment that are normally associated with a system. Seeds or cuttings are put in a growing medium and wicks, which are often nylon or cotton, draw nutrients from a container to the plant roots. This system is more effective when used with small plants such as herbs and green leafages since big plants may not develop enough nutrients from the wicking process.
Pros: Easy to set up, low maintenance
Cons: Not suitable for large plants, slow in nutrient delivery
2. Deep Water Culture (DWC)
DWC or deep water culture is one of the most used hydroponic systems that are widely used all over the world. In this method, the roots of the plant are placed and hung in a nutrient solution containing water. An air pump supplies oxygen to the roots through air stones so the plants don’t suffocate. This system is quite effective and promotes fast plant growth, which will be very ideal for crops such as lettuce, spinach and herbs.
Pros: Easy to control and fast growing plant.
Cons: Susceptible to root diseases if it is not well tended
3. Nutrient Film Technique (NFT)
The Nutrient Film Technique is even a more developed hydroponic system. A steady supply of nutrient solution is passed over the plant root which is suspended in channels. This system has the need for a pump so as to provide constant supply of nutrients to the roots. NFT is best used for light crops like lettuce but it may not well support heavy plants if not supplemented by some support.
Pros: These include; sustained provision of nutrients, water and nutrient utilization.
Cons: Plants can become dehydrated very fast due to pump failure
4. Flood and Drain, also known as Ebb and Flow, System
The Ebb and Flow system is based on the ability to flood the grow tray with nutrient solution and then allow the water to drain back into the reservoir. This system is perfect for raising plants in a number of different types of media such as clay pebbles, gravel, or Rockwool. It also makes certain the plant roots are well supplied with both food and air as the water seeps away periodically.
Pros: It can grow in different media and can support almost all types of plants.
Cons: This means that the flood cycle must be checked frequently, the failure of the pump is a stress to the plant
5. Drip System
A drip hydroponic system involves a system of tubes and emitters that slowly and continuously drip nutrient solutions to the roots of the plant. This system can be recirculating in which the excess nutrient solution is collected and used again or non-recirculating, in which the excess nutrient solution drains away. Drip systems provide flexibility in irrigation and are appropriate for use with most crops including vegetables and flowers.
Pros: Very flexible, suitable for use with almost any type of plant.
Cons: Drip emitters have a disadvantage since they are likely to be blocked sometimes in the future, it needs irrigation.
6. Aeroponics
Aeroponics is actually considered to be one of the most sophisticated and technologically complex hydroponic systems. The technique is characterized by the suspension of plant roots in the air and spraying of the nutrient solution at intervals. This system provides the highest efficiency of oxygen delivery to the roots and nutrient absorption thus faster rates of growth. But it has to be done with high accuracy as to the frequency and concentration of the misting solution.
Pros: Fast-growing plants, very effective nutrient transport
Cons: It is costly to implement, needs close supervision and regulation
Conclusion
Hydroponics is an exciting and very efficient method that allows the growth of plants without the use of soil and is ideal for the modern garden. Every one of the hydroponic systems from the wick system to the aeroponics has its own advantages that may suit the grower depending on the type of plant and the grower’s expertise. Whether it is a fast-growing herb or a nutrient-hungry vegetable, the right system can add a lot of value to your plant’s growth and production.
The most important factor in making a decision on which hydroponic system to choose is to determine what your gardening needs and wants are, the types of plants you wish to cultivate and what you have at your disposal. Irrespective of your level of experience with hydroponics, whether you are new to it or you are an experienced farmer, you will find that hydroponics has something special to offer you. If you get to understand these systems you can grow an all-year-round productive garden regardless of the amount of space and zone you live in.
