4. Planting the Seeds

Germinate the Seeds: Start by germinating green bean seeds in a moist paper towel until they sprout.
Transplant the Seedlings: Place the germinated seeds into the net pots filled with the growing medium. The roots should be in contact with the nutrient solution.

5. Maintaining the System

Monitor pH and Nutrient Levels: Regularly check the pH and nutrient levels of the solution, adjusting as necessary.
Light: If you’re growing indoors, ensure your plants get 14-16 hours of light per day using grow lights.
Water and Nutrient Solution: Top up the nutrient solution as it gets used up and change it completely every 2-3 weeks to prevent nutrient imbalances.
Temperature and Humidity: Keep the temperature between 65-75°F (18-24°C) and humidity around 50-70%.

6. Caring for Your Plants

Pruning: Trim any dead or yellowing leaves to promote healthy growth.
Pollination: Green beans typically self-pollinate, but gently shaking the plants can help if needed.
Pest Control: Inspect plants regularly for pests and use natural or hydroponic-safe pest control methods if necessary.

7. Harvesting

Timing: Green beans are usually ready to harvest about 50-60 days after planting. Look for beans that are firm and crisp.
Method: Use scissors or a sharp knife to cut the beans off the plant to avoid damaging the plant.

8. Tips for Success

Consistency: Maintain consistent water levels and nutrient concentrations.
Cleanliness: Keep your hydroponic system clean to prevent algae growth and disease.
Observation: Regularly inspect your plants and system to catch any issues early.

By following these steps, you should be able to grow a thriving hydroponic green bean garden. Happy gardening!
