How to Make Organic Hydroponics Fertilizer


Hydroponics is the technique of growing plants without soil. Some hydroponic designs use only nutrient-enriched water. Make your own organic fertilizer for your hydroponics growing system with compost tea. Add the compost tea to your plants and watch them grow.

Things You'll Need

  • Compost pile
  • Plastic garbage can with tight-fitting lid
  • Spray bottle or watering can
  • Create a compost pile. Add a variety of natural ingredients to the compost pile, such as egg shells, coffee grounds, manure, leaves, yard waste and fruit and vegetable peels. Allow the compost pile to rot for a few weeks. Regularly turn and water the pile to speed decomposition.

  • Fill a plastic garbage can half with compost, and the rest of the way with water. Cover the can with the lid and allow it to stand in the sun for a week or two.

  • Stir the contents of the garbage can every day to allow the mixture to breath and absorb oxygen.

  • Pour some of the tea into a spray bottle or watering can and top it off with water; use about a one-to-five ratio of tea to water. Add to your plants, as necessary.

Tips & Warnings

  • Your compost pile and tea should not smell rotten. If they do, add more fresh water and stir more often.
