Growing hydroponic celery in recycled plastic bottles is an innovative and cost-effective way to produce fresh and healthy celery at home. Hydroponic systems provide nutrients directly to the plants’ roots in a soilless environment. Here’s a simple guide on how to grow cheap hydroponic celery using recycled plastic bottles:

Materials Needed:

  1. Recycled Plastic Bottles:
    • Use large plastic bottles with caps. Cut them in half horizontally, keeping the upper part with the cap.
  2. Net Pots or DIY Net Cups:
    • Create net pots from plastic containers or use pre-made net pots to hold the celery plants.
  3. Hydroponic Nutrient Solution:
    • Choose a balanced hydroponic nutrient solution suitable for vegetables. Follow the manufacturer’s instructions for dilution.
  4. Growing Medium:
    • Use a soilless growing medium like perlite, coconut coir, or a hydroponic growing medium.
  5. Celery Seeds or Seedlings:
    • Purchase celery seeds or seedlings from a nursery or garden center.
  6. Hydroponic System Setup:
    • Set up a simple hydroponic system using the plastic bottles, net pots, and nutrient solution.
  7. Support Structures:
    • Install support structures or racks to hold the plastic bottles in place and allow the celery to grow vertically.
  8. Light Source:
    • Place the hydroponic system in a location with sufficient natural sunlight or use artificial grow lights.

Steps:

  1. Prepare the Plastic Bottles:
    • Cut the plastic bottles in half horizontally. Keep the upper part with the cap. This will serve as the container for the celery plant.
  2. Create Net Pots or Use Pre-made Net Cups:
    • Cut or obtain net pots that fit into the mouth of the plastic bottles. These will hold the celery plants in place.
  3. Fill Net Pots with Growing Medium:
    • Fill the net pots with the chosen soilless growing medium.
  4. Plant Celery Seeds or Seedlings:
    • Plant celery seeds or transplant seedlings into the net pots filled with the growing medium.
  5. Prepare the Hydroponic Nutrient Solution:
    • Mix the hydroponic nutrient solution according to the manufacturer’s instructions.
  6. Hydroponic System Setup:
    • Fill the lower halves of the plastic bottles with the nutrient solution.
    • Place the net pots with celery plants into the mouths of the plastic bottles, allowing the roots to reach the nutrient solution.
  7. Support Structures:
    • Set up support structures or racks to hold the plastic bottles in a vertical position. This allows the celery to grow upward.
  8. Provide Adequate Light:
    • Ensure that the hydroponic system receives sufficient natural sunlight or artificial grow lights for at least 6-8 hours per day.
  9. Maintain Nutrient Levels:
    • Regularly monitor the nutrient solution levels and top up with fresh solution as needed.
  10. Harvesting:
    • Harvest celery stalks when they reach the desired size. Cut the stalks at the base, leaving the plant to continue producing.

Tips:

  • Recycling Bottles: Consider using bottles of the same size for uniformity. Ensure that the plastic bottles are thoroughly cleaned before use.
  • Nutrient Solution Management: Regularly check and adjust the nutrient solution’s pH and concentration to meet the celery’s needs.
  • Vertical Growing: Utilize the vertical space efficiently by arranging the plastic bottles in a vertical tower or hanging system.

By following these steps, you can create a simple and cost-effective hydroponic system for growing celery in recycled plastic bottles. This method allows for efficient use of space, water, and nutrients, resulting in a high-yield harvest of fresh and crisp celery.
