How is natural lighting better than artificial for ponds?

1. Natural light is full-spectrum. This means that it contains all of the wavelengths of light that are visible to the human eye, as well as some that are not. Artificial light, on the other hand, is typically only composed of a few wavelengths of light, which can lead to a distorted or unnatural appearance.

2. Natural light is more consistent. The intensity and color of natural light change gradually over the course of the day, which helps to create a more natural environment for pond plants and animals. Artificial light, on the other hand, can be inconsistent and may fluctuate in intensity and color, which can stress pond organisms.

3. Natural light is less expensive. In most cases, natural light is free, while artificial light requires the use of electricity. This can be a significant cost savings, especially for large or heavily planted ponds.

While there are some cases in which artificial light may be necessary for ponds, such as when the pond is located in a shady area or when it is used for night viewing, natural light is always the best choice when possible.
