Growing hydroponic green onions in plastic cups

Hydroponic cultivation is an innovative method of growing earthless plants, using only water and nutrients. Green onions are delicious plants that are easy to grow in hydroponia. In this article, we will guide you step by step to grow hydroponic green onions in plastic cups, a simple and productive method within everyone’s reach.

Materials required:

  • Transparent plastic cups
  • Green onion seeds
  • Hydroponic culture substrate
  • Hydroponic nutrients
  • Water
  • Artificial lighting

Steps in hydroponic cultivation of green onions:

1. Preparation of cups: Drill small holes at the bottom of plastic cups to allow drainage of water. Fill the cups with hydroponic substrate until 3/4 of their height.

2. Seed planting: Place one or two green onion seeds in each cup, bury them slightly in the substrate and cover them with a few centimetres of substrate.

3. Watering and Nutrition: Water the freshly planted seeds with water until the substrate is moistened. Then dilute the hydroponic nutrients in the water according to the manufacturer’s instructions and water your plants with this nutrient solution at regular intervals.

4. Lighting: Green onions need a lot of light to grow properly. Place the cups in a well-lit place or use artificial lighting if necessary, ensuring that plants receive about 12 to 16 hours of light per day.

5. Maintenance: Regularly monitor substrate moisture and plant health. Make sure the roots are not too wet to avoid rot problems. Remove weeds and dead leaves as needed.

6. Harvest: Green onions can be harvested when the stems reach a height of about 15 to 20 centimetres. You can cut the stems to the desired level and use them in your favorite dishes to add a fresh and delicious flavor.

Benefits of hydroponic green onions:

  • Faster production than traditional earth culture
  • Less space required, ideal for small spaces
  • Accurate control of nutrients for optimal growth
  • Less risk of disease and pests
  • Fresh green onions at hand all year round

By following these simple steps, you can easily grow hydroponic green onions in plastic cups at home. Enjoy the freshness and unique flavour of your own crops while exploring this innovative and productive cultivation method.
