Hydroponic Greenhouse for Outdoors Cultivation

Introduction to Hydroponic Greenhouse for Outdoors Cultivation

In recent years, hydroponics has gained significant popularity due to its efficiency and sustainability. Hydroponic greenhouses take this concept to the next level by creating an ideal environment for plants to thrive, regardless of the external conditions. By eliminating the need for soil, hydroponics maximizes resource utilization and minimizes water consumption. The controlled environment of a greenhouse further enhances the growth process, enabling growers to cultivate crops throughout the year.

Understanding Hydroponic Greenhouses

Hydroponic greenhouses combine the principles of hydroponics and greenhouse cultivation. In hydroponics, plants are grown in a nutrient-rich water solution, allowing their roots to directly access the necessary elements for growth. Greenhouses provide a controlled environment with regulated temperature, humidity, and light, shielding plants from harsh weather conditions. By combining these two techniques, growers can optimize plant growth, increase crop yields, and extend the growing season.

Benefits of Hydroponic Greenhouses

The utilization of hydroponic greenhouses offers numerous benefits for both commercial and hobbyist growers. Firstly, the controlled environment allows for precise control over key factors such as temperature, humidity, and light intensity, optimizing plant growth and minimizing the risk of pests and diseases. Additionally, hydroponics enables the efficient use of resources, such as water and nutrients, leading to higher yields with lower environmental impact. Furthermore, the ability to cultivate crops year-round ensures a consistent supply of fresh produce, reducing dependency on seasonal availability and long-distance transportation.

Types of Hydroponic Greenhouses

There are several types of hydroponic systems that can be implemented within a greenhouse setting. Let’s explore some of the popular options:

1. Nutrient Film Technique (NFT)

NFT systems involve a shallow stream of nutrient-rich water flowing over the plant roots, allowing them to absorb the required nutrients. This method is highly efficient in water usage and is suitable for growing leafy greens and herbs.

2. Deep Water Culture (DWC)

DWC systems suspend plant roots in a nutrient solution, providing a constant supply of oxygen. This technique is particularly effective for cultivating larger plants like tomatoes and cucumbers, promoting robust growth and healthy yields.

3. Ebb and Flow (Flood and Drain)

Ebb and Flow systems periodically flood the plant roots with nutrient solution and then drain it back into a reservoir. This method ensures good oxygenation of the root system and is versatile enough to accommodate a wide range of crops.

4. Aeroponics

Aeroponic systems mist the plant roots with a nutrient solution, allowing for maximum oxygen exposure. This technique is known for its rapid growth rates and is ideal for delicate plants like lettuce and strawberries.

Choosing the Right Greenhouse Structure

Selecting the appropriate greenhouse structure is crucial for successful hydroponic cultivation. Let’s explore some common options:

1. Traditional Glass Greenhouses

Glass greenhouses provide excellent light transmission, creating an optimal environment for plants. They offer superior insulation and durability but tend to be more expensive to construct and maintain.

2. Polycarbonate Greenhouses

Polycarbonate greenhouses are lightweight, affordable, and offer good insulation properties. They are resistant to impact and provide diffused light, reducing the risk of plant scorching. However, they may require additional shading in hot climates.

3. High Tunnel Greenhouses

High tunnel greenhouses are cost-effective structures that use a polyethylene covering. They are ideal for extending the growing season in regions with milder climates and can be easily assembled and disassembled.

Setting Up a Hydroponic Greenhouse

To set up a hydroponic greenhouse, careful planning and consideration are necessary. Here are some key steps to guide you:

1. Selecting the Location

Choose a location that receives ample sunlight and is accessible for maintenance. Ensure proper ventilation to prevent excessive heat buildup and humidity.

2. Controlling Temperature and Humidity

Install appropriate heating and cooling systems to maintain optimal temperature and humidity levels. This will vary depending on the crops being cultivated and the external climate.

3. Choosing the Growing System

Select a hydroponic system that aligns with your goals and available resources. Consider factors such as space, crop selection, and your level of expertise.

Space & Area Considerations for your Hydroponics System

The space or area required for hydroponic greenhouses can vary depending on the specific system and crop being cultivated. Here’s some further information about the space requirements for various hydroponic greenhouses:

  1. Nutrient Film Technique (NFT): NFT systems are designed with sloping channels where a thin film of nutrient-rich water flows over the plant roots. The space required for NFT systems can be relatively compact since the plants are positioned in channels, allowing for vertical stacking and efficient use of space. Depending on the desired capacity, NFT systems can be set up in small-scale indoor setups or larger commercial greenhouse facilities.
  2. Deep Water Culture (DWC): DWC systems involve suspending plant roots in a nutrient solution, typically in large containers or floating rafts. The space required for DWC systems can vary depending on the size and number of plants being grown. It is important to provide enough space between the containers or rafts to allow for proper circulation and oxygenation of the nutrient solution.
  3. Ebb and Flow (Flood and Drain): Ebb and Flow systems consist of periodically flooding the plant roots with nutrient solution and then draining it back into a reservoir. The space required for Ebb and Flow systems depends on the number of plants and the size of the flood trays or containers used. It is essential to have enough space to accommodate the trays and ensure proper drainage.
  4. Aeroponics: Aeroponic systems mist the plant roots with a nutrient solution, typically in a highly oxygenated environment. The space required for aeroponic systems can vary depending on the design and scale of the setup. Aeroponic systems often involve vertical towers or racks to maximize space utilization, making them suitable for both small-scale and large-scale operations.

When determining the space requirements for a hydroponic greenhouse, it is essential to consider factors such as the type and number of plants being cultivated, the desired production capacity, and the available area for the greenhouse structure. Additionally, adequate space should be allocated for walkways, access to equipment, and maintenance activities.

It is recommended to consult hydroponic greenhouse suppliers, designers, or experts who can provide specific guidance based on your needs and available space.

Tips for Successful Hydroponic Greenhouse Cultivation

To ensure successful hydroponic greenhouse cultivation, consider the following tips:

1. Ensuring Proper Nutrient Balance

Regularly monitor and adjust the nutrient solution to maintain the proper balance of essential elements for healthy plant growth. Conduct regular water quality tests to avoid nutrient deficiencies or toxicities.

2. Managing pH Levels

Maintain the pH levels of the nutrient solution within the appropriate range for the specific crop being grown. This ensures optimal nutrient uptake and prevents nutrient lockout.

3. Maintaining a Clean System

Regularly clean and sanitize your hydroponic system to prevent the buildup of algae, bacteria, and pests. Proper maintenance will help minimize the risk of diseases and ensure the longevity of your system.


Hydroponic greenhouses offer a promising avenue for year-round, high-yield cultivation. By combining the principles of hydroponics and greenhouse cultivation, growers can optimize plant growth, minimize resource consumption, and extend the growing season. Whether you are a commercial farmer or a passionate hobbyist, the utilization of hydroponic greenhouses provides a sustainable and efficient approach to agriculture.
