What Are Hydroponic Systems and How Do They Work?

Hydroponic systems are some of the most efficient and effective ways to grow plants without the need for a traditional soil-based garden. There are several different types of hydroponic systems, each with its own unique benefits. 

What is hydroponics? 

Plant cultivation without soil, known as hydroponics, involves nourishing plants with nutrient- enriched solutions, oxygen and water. This allows for faster growth and yields of a higher quality compared to soil grown plants. Instead of requiring energy for the root system to locate food and water, hydroponically-grown plants are nourished directly through their root systems. As a result, this redirects energy into increased leaf growth and fruit or flower blooming capacity. Photosynthesis powers the plants’ sustenance in which sunlight is captured using chlorophyll found in leaves to separate absorbed water molecules via the roots. Hydrogen molecules combine with carbon dioxide before being transformed into carbohydrates for nutrition with oxygen released in the process for sustaining life on our planet's surface. Water and nutrients can be applied more directly via flooding, misting or fully immersing them in water, which produces better results than conventional irrigation.

How does hydroponics work? 

Hydroponic systems offer plants optimal growth conditions by providing precision control over environmental conditions such as temperature, pH balance and availability of essential nutrients and water. The main idea behind hydroponics is to supply plants with just what they need, when they need it and in the exact amounts necessary. Nutrient-rich solutions tailored to the type of plant that is being cultivated can be distributed through hydroponic systems; into which light can also be controlled and managed. Furthermore, pH levels can also be monitored and modified, ultimately leading to accelerated plant growth in a much more regulated environment than gardens or open fields can provide. Pests, soil-borne fungus and animals like rabbits cannot interfere with growth when using a hydroponic system, thus eliminating some of the unpredictability that external factors present in outdoor growings. Moreover, due to the fact that there is no mechanical resistance from soil, seedlings are able to reach maturity faster. Ultimately, this means healthier produce without pesticides that is of a higher quality than its soil-grown counterpart. Hydroponics offers plants a realm in which obstacles have been eliminated so as to encourage rapid and vigorous growth.

What are the six types of hydroponic systems?

There are hundreds of hydroponic methods, but all of them are a modification or combination of six basic hydroponic systems.

1. Deep water culture systems 

Deep water culture (DWC): Deep Water Culture hydroponic setup allows plant roots literally sit in circulating nutrient solution tanks filled with oxygenated water that has been saturated by anaerobic bacteria which allows oxygen together with necessary minerals (nutrients) absorbed within this set up makes this type of hydroponics extremely successful style of growing any vegetable and/or fruit in minimal time period compared with traditional gardening techniques used outdoors based on soil growth cycle .  

    2. Wick systems 

    This type of system works by utilizing capillary action to bring water and nutrients up from the reservoir to the plant roots. They are simple setups that require low maintenance, making them an ideal choice for beginner gardeners. 

        3. Nutrient film technique systems

        Nutrient Film Techniques (NFT): With NFT instead of flooding roots with nutrient solution over multiple times like ebb & flow, Roots only get complete exposure within thin film of nutrient solution constantly flowing over top through entire length of channel tray containing multiple cuttings / seedlings being farming out simultaneously .   

          4. Ebb and flow systems

          Ebb and flow systems: Also known as flood and drain systems, these setups use pumps to flood the roots with a nutrient solution from time to time. This system is great for automation, as it can be set on a timer to save the gardener time and energy in caring for their plants. 

            hydroponic drip system


            5. Drip systems 

            Drip systems work by slowly delivering water and nutrients directly to each individual plant’s root system through a network of tubes and emitters. The slow delivery helps insure all nutrients reach their destination without overly saturating any one part of the garden area, making them another great option for automating hydroponic gardening projects.

            6. Aeroponics 

            Aeroponics is a soilless system which uses misted oxygen-rich nutrient solutions along with air or rockwool medium’s or other substrates to provide adequate rooting space to each individual plant while still providing easy access to nutrients and water when needed.  


            These six types cover the most common forms of hydroponic gardening, allowing gardeners to pick one that meets their needs perfectly. Each setup offers its own unique benefits, allowing growers more control over their gardens even in limited spaces so they can maximize yields while minimizing effort and cost
