Equipment Required To Start Hydroponic Gardening

There are tons of places to buy supplied for hydro gardening. Even big box retail stores are selling grow lights and other accessories. However, if you want to run a turnkey garden you will need a little more than those companies can offer.

Widely recognized and respected in the hydroponics community, General Hydroponics, Inc offers a comprehensive range nutrients, supplements, maintenance supplies and accessories.

Known for its extensive product catalog, Hydrofarm is a major distributor providing a diverse array of hydroponic equipment, grow lights, and environmental control solutions. They specialize in supplying commercial growers.

Renowned for its focus on hydroponic nutrients and supplements, Advanced Nutrients has a significant presence in the industry and is often preferred by growers looking to optimize plant growth.

Types of Hydroponic Systems

There are five primary types of hydroponic systems, and dozens of variations for each. For example, Dutch Buckets are a common hydro setup, and are a variation of DWC and a drip system. Here are all five hydroponic garden systems:

1. Nutrient Film Technique (NFT)

Plants are placed in channels or gullies with a slight slope, allowing a thin film of nutrient solution to continuously flow over the roots. The nutrient solution is pumped to the highest end of the channel, and gravity allows it to flow over the roots of the plants. Excess nutrients are collected and recirculated.

The roots are suspended in the film of nutrient solution, absorbing water and nutrients directly. This promotes efficient nutrient uptake and oxygenation. NFT systems operate continuously, providing a consistent flow of nutrients to the plants. The film of nutrient solution is typically very shallow, ensuring that the roots receive both nutrients and oxygen.

2 – Deep Water Culture (DWC)

DWC is a hydroponic system where plant. Plants are placed in net pots, and their roots dangle directly into a reservoir filled with nutrient-rich water. Air stones or diffusers provide constant oxygen to the submerged roots, promoting optimal nutrient absorption.

The nutrient solution is continuously circulated. Doing so ensures a consistent supply of nutrients to the plants. The plant roots are buoyant in the nutrient solution, providing stability for the plants while facilitating nutrient absorption. DWC systems are used for larger plants. (e.g. tomatoes and peppers). They can be adapted for various crops.

Regular monitoring of nutrient levels, pH, and oxygenation is essential for maintaining a successful DWC hydroponic system.

3. Drip System

A Drip Hydroponic System is a method where nutrient-rich water is dripped directly onto the base of each plant. In a drip system a pump delivers the nutrient solution to a network of tubing or pipes. Doing so helps deliver a controlled and measured amount of nutrient solution.

Excess nutrient solution not absorbed by the plants is collected and recirculated back to the main reservoir. Drip systems are suitable for a wide range of crops.

Drip systems are popular for their flexibility, ease of automation, and suitability for both small and large-scale hydroponic setups. Regular maintenance, including checking for clogs and ensuring proper nutrient concentration, is essential for optimal performance.

4. Wick System

A Wick Hydroponic System is a passive, simple, and low-cost hydroponic method that uses capillary action to deliver nutrient solution to plant roots. In a wick system plants are placed in a growing medium, such as coconut coir or perlite, which surrounds a wick made of materials like felt or cotton. The wick draws up nutrient solution from a reservoir through capillary action. Capillary action is the movement of a liquid through a narrow space without the assistance of external forces like gravity. 

The wick draws up nutrient solution from a reservoir through capillary action. Plant roots absorb the nutrient-rich water directly from the growing medium, facilitated by the wick’s continuous delivery.

Wick systems operate without the need for pumps or electricity, relying on the natural capillary action of the wick. While efficient for smaller plants with modest nutrient requirements, wick systems may not be as suitable for larger or high-demanding crops. Regular monitoring of nutrient levels and occasional adjustment of the wick may be necessary for optimal performance.

5. Aeroponics

In an aeroponic system a high-pressure pump and misting nozzles deliver a nutrient solution in the form of fine mist or droplets directly to the exposed roots. Plants are usually supported on a platform, and their roots hang freely in the air within the growing chamber.

The misting process ensures that roots receive both nutrients and high levels of oxygen, promoting rapid growth. The fine mist allows for precise nutrient absorption, promoting faster nutrient uptake by the plants. Excess nutrient solution is collected, filtered, and recirculated, making aeroponics a water-efficient system.

Aeroponic systems are versatile and suitable for various crops, from small herbs to larger plants like tomatoes and peppers. Aeroponic systems often incorporate sensors and controllers to monitor and maintain optimal nutrient levels, pH, and temperature.

While it can be more complex to set up and manage, aeroponic systems offer advanced control over the plant environment, making them a choice for serious hydroponic enthusiasts and commercial growers. Regular maintenance and monitoring are essential for sustained success in aeroponic gardening.
