Introduction

This tutorial will guide you through the simple process of growing red onions in water, using basic materials such as Styrofoam and plastic bottles. This method is suitable for beginners and allows you to grow red onions without soil, making it cleaner and more efficient. You'll see results in less than two days as the roots start to grow.

Step 1: Gather Your Materials

To start, you'll need the following items:

• Fresh red onion bulbs
• A Styrofoam container or a plastic bottle (like an Aqua bottle)
• Water
• Nutrient solution (optional, for enhanced growth)

Practical Tips:

• Choose healthy onions without any signs of rot or damage.
• If using a plastic bottle, cut it in half to create a suitable container.

Step 2: Prepare the Container

• If using Styrofoam:

  • Cut a hole in the center of the Styrofoam to hold the onion bulb securely.
  • The bulb should sit on top of the container, with the roots hanging down into the water.

• If using a plastic bottle:

  • Fill the bottom half with water, leaving enough space for the onion bulb to rest on the top.
  • Ensure the cut part allows the bulb to be held securely.

Step 3: Place the Onion in the Container

• Position the onion bulb so that the roots are submerged in water while the top is above the water line.
• If using a nutrient solution, mix it with water according to the instructions and fill the container.

Step 4: Position the Setup

• Place your setup in a location with indirect sunlight. Too much direct sunlight can overheat the water, harming the roots.
• Ensure the container is stable and won’t tip over easily.

Step 5: Monitor Water Levels

• Check the water level daily to ensure the roots remain submerged.
• Refill with fresh water as needed to prevent the bulb from drying out.

Step 6: Observe Growth

• Within two days, you should notice roots starting to grow.
• After about a week, the green shoots will begin to sprout, indicating healthy growth.

Conclusion

Growing red onions in water is a straightforward and rewarding process. By following these steps, you can successfully cultivate onions without soil. Remember to keep an eye on water levels and light exposure for optimal growth. Once you're comfortable with this method, consider experimenting with other hydroponic plants for a diverse home garden.
