Benefits of growing cucumbers hydroponically
- Year-Round Cultivation: With hydroponics, we can cultivate cucumbers year-round, independent of seasonal limitations. This continuous production ensures a steady supply of fresh cucumbers.
- Higher Yields: Hydroponic cucumber plants tend to produce larger and more abundant fruits compared to soil-grown plants. The controlled environment and optimized nutrient supply promote vigorous growth leading to increased productivity.
- Minimized weeding and soil-borne issues: By eliminating soil, hydroponic systems eliminate the need for regular weeding and reduce the risk of soil-borne diseases and pathogens. This saves time and labor as well.
- Sustainable and Controlled Farming: growing cucumbers in a hydroponic system reduces water usage, minimizes nutrient runoff, and eliminates the need for synthetic fertilizers.

How to Start–
To start the seeds of the cucumber in a hydroponic system, it’s not recommended to leave them in water until they germinate. A more suitable medium such as coco coir or mineral wool should be provided. The seeds themselves have a high rate of germination and take between 3 to 10 days to sprout.
Choosing the appropriate hydroponic system
- Nutrient Film Technique (NFT): A shallow channel or gully system where a thin film of nutrient solution flows over the roots
- Ebb and flow: Plants sit in a grow tray that periodically floods with nutrient solution and drains afterward.
- Deep Water Culture (DWC): plants are suspended in a nutrient solution with the roots submerged.
- Drip System: The nutrient solution is delivered through drip emitters directly to the base of each plant.
Hydroponic systems come in many shapes, sizes, and varieties. Each has its own advantages and works for certain plants. When it comes to cucumbers, the best hydroponic systems are the drip system, the ebb-and-flow system, and the Dutch bucket system.
Preparation of growing area and setting up the system
- Choose an area with ample sunlight exposure or a layout plan for artificial lighting.
- Assemble the components of your chosen hydroponic system, following the instructions of the manufacturer.
- Install water pumps and lighting system as per requirement.
- Arrange the growing trays or containers in a way that provides proper spacing for cucumber plants to grow.
- Follow the instructions provided by the nutrient solution manufacturer to prepare a solution.
- Use the pH and EC meters to adjust the pH level and nutrient concentration as needed.
- Carefully transplant the cucumber seedlings into the growing medium, ensuring their roots are adequately covered.
- Regularly check the nutrient solution levels, pH, and EC values to maintain optimal conditions.

Favorable growing conditions for hydroponic cucumber
- Temperature: Cucumber plants thrive in warm temperatures, typically between 21-29°C during the day and slightly cooler at night. Maintain a consistent temperature within this range to encourage optimal growth and prevent stress.
- Air Circulation: Good air circulation is essential for preventing stagnant air, reducing humidity and minimizing the risk of pests or diseases. Use fans or install an air circulation system to promote adequate air exchange around the plants.
- pH and Nutrient Levels: hydroponic cucumbers grow well in a slightly acidic to neutral pH range of 5.5-6.5. Regularly monitor and adjust the pH of the nutrient solution to ensure optimal nutrient availability and absorption. Conduct regular water and nutrient solution testing to ensure they meet the plant requirements.
- Light: Cucumbers are high-light plants and require at least 12-16 hours of direct or indirect sunlight each day. If growing indoors or in low-light conditions, use high-quality artificial lighting, such as LED or fluorescent grow lights.
- Humidity: Cucumbers prefer moderate humidity levels, ideally around 60-70%. High humidity can increase the risk of fungal diseases, so ensure proper air circulation and ventilation to prevent excess moisture build-up.
