Growing spinach hydroponically is straightforward and efficient. Here’s how to do it in just six simple steps:
– Choose a System: Deep Water Culture (DWC) or Nutrient Film Technique (NFT) works well for spinach. – Setup: Ensure your system has good aeration and water flow.
– Use Rockwool or Coco Coir: These are ideal for starting spinach seeds. – Soak the Medium: Before planting, soak it in pH-balanced water (pH 6.0-7.5)
– Sow Seeds: Place 2-3 spinach seeds in each hole of the growing medium. – Germination: Keep the medium moist and in a warm, dark place until seeds germinate (5-10 days).
– Use Grow Lights: Place LED grow lights 6-12 inches above the seedlings. – Light Cycle: Provide 12-16 hours of light daily.
– Mix Nutrients: Use a hydroponic nutrient solution specifically for leafy greens. – Monitor pH: Keep the pH level between 6.0 and 7.5, and check it regularly.
– Harvest Time: Spinach is ready to harvest in 4-6 weeks. – Pick Leaves: Cut the outer leaves first, allowing the plant to continue growing.
