Step-by-Step Instructions
1. Plan your layout by dividing the 3m x 3m greenhouse into zones for different plant types, using vertical shelving if desired to maximize space.
2. Set up the water reservoir in a shaded corner of the greenhouse to keep water cool.
3. Install hydroponic grow trays or channels on stands at a slight angle (1-3%) to allow nutrient solution to flow via gravity.
4. Connect the submersible pump inside the reservoir to PVC tubing that feeds nutrient solution to the upper end of each grow tray.
5. Arrange the return tubing at the lower end of each tray to channel excess solution back into the reservoir.
6. Seal all tubing connections with waterproof sealant to prevent leaks.
7. Fill net pots with your chosen growing medium and place seedlings or seeds inside.
8. Insert net pots into holes in the grow trays or into DWC buckets filled with nutrient solution.
9. Calibrate and fill the reservoir with water and add the recommended amount of hydroponic nutrients; check pH and EC levels.
10. Set the timer to run the pump in intervals (e.g., 15 minutes on, 45 minutes off) to keep roots moist without waterlogging.
11. Monitor water levels, nutrient concentration, and plant health regularly, topping up and adjusting as needed.
12. Optionally, install a small fan to improve air circulation and prevent mold.
13. Maintain cleanliness by flushing the system every 2-4 weeks to prevent buildup and algae growth.
