How to grow pennywort hydroponically until it overflows the pot?

As a popular plant, many friends like to grow a pot of pennywort at home, but many people will find that no matter how they grow it, there is no sign of growing leaves. The problem of slow growth or cessation of growth of pennywort is mainly related to insufficient light and lack of nutrients. So how do you grow pennywort hydroponically to make it overflow the pot?

1. Light and substrate

Hydroponic pennywort requires strong sunlight to support its photosynthesis so that it can absorb nutrients in the water more efficiently. Photosynthesis is the energy basis for the growth of green plants, and the same is true for pennywort. In summer, strong direct sunlight should be avoided and the plant should be placed in a place with sufficient diffuse light to ensure that it can receive 4 to 5 hours of light every day. In winter or when there is insufficient light, fluorescent lamps can be used for supplementary lighting. Adding an appropriate amount of river sand to the water can enhance the root fixation and provide additional nutrients to promote the rapid growth of pennywort.

2. Clear water quality

The hydroponic environment of copper coin grass requires a clean and pollution-free water source. Water that is not changed for a long time is prone to breed impurities such as green algae and insect eggs. At the same time, the consumption of dissolved oxygen in the water will also affect the root respiration of the pennywort. Therefore, regular water changes are the key to ensuring the healthy development of the roots of the pennywort. The recommended frequency of water changes is every 3 days in summer, every 7 days in winter, and every 5 days in spring and autumn. When changing water, it is recommended to only replace half of the water volume to retain nutrients that have not been fully absorbed in the water.

3. Root system and nutrient absorption

The roots of the pennywort can penetrate river sand and absorb nutrients from it. With sufficient sunlight, the root system's nutrient absorption efficiency will be significantly improved, allowing the pennywort to cover the entire pot in just a dozen days.

4. Suitable temperature

The pennywort is sensitive to temperature, and too high or too low temperature will affect its normal growth. 15℃ to 26℃ is the most suitable temperature range for the growth of pennywort. In summer, shade measures should be taken to avoid heat damage, and in winter, it should be moved indoors to keep warm.

5. Advantages of outdoor farming

Planting pennywort in a large basin of water and placing it outdoors, such as on a patio, will help it grow quickly within two weeks, making its leaves larger, greener, and its stems thicker.

6. Transplantation and ornamental value

After the pennywort fills the basin, you can select some large pennywort plants for transplanting and place them in a water bottle indoors. The pennywort grown outdoors not only grows quickly, but also has larger leaves and is more ornamental.

7. Differences between indoor and outdoor environments

The environmental conditions indoors and outdoors are different. Under the high temperature outdoors in summer, the growth rate of pennywort can be doubled, and the leaves will be more lush, which is better than indoor cultivation.

8. Proper pruning

Since pennywort grows rapidly when hydroponically cultivated, if the leaves are too dense, it will not only affect ventilation but may also increase the risk of disease. Promptly pruning off yellow, diseased or overcrowded branches and leaves, and using fungicides to treat the wounds will help maintain plant health and reduce the occurrence of diseases.

In short, the success of hydroponics of pennywort depends largely on light conditions and nutrient absorption by the roots. By providing suitable light and substrate, the rapid growth and lush development of pennywort can be effectively promoted.
