How to hydroponically plant onions
Today's experience sharing: topics related to how to hydroponically plant onions, including methods of hydroponic onion cultivation. Let's take a look together.
1. Hydroponic method: Prepare a healthy and plump onion bulb, peel off its rotten skin, and trim the bottom part with poor growth or too messy roots. Then prepare a cup with a rim slightly smaller than the diameter of the onion bulb, fill it with water, and gently place the onion on the rim, allowing its bottom to touch the water surface.
2. Temperature: It grows best in an environment of 13-22°C. When maintaining it, try to keep it in a warm indoor place, which is more beneficial for its growth.
3. Lighting: In the early stages of maintenance, it can be exposed to light sparingly. However, once it grows new leaves, it must be provided with plenty of sunlight. This will allow it to synthesize more nutrients and speed up its growth.
4. Water changing: In the first week of maintenance, you need to change the water every day. This will help it root faster. When it grows new roots, you can change the water every 2-3 days.
5. Adding root promoting powder: If it roots too slowly, you can add a small amount of root promoting powder to the water and stir it well. This will help it grow roots faster.
