How to Choose Plant Lights Based on Different Environments?

Before choosing a LED plant light, consider the area you are growing plants in, the environment you will be using it in, and what performance capabilities you need. The adaptability of LED plant lights can generally be analyzed based on the planting area, plant characteristics, and plant growth environment.

Planting area for led plant lights

Depending on the size of the planting area, the shape of the led plant light is primarily determined. Generally, square and circular designs are used for led plant lights. For a single plant supplement light, using a circular led plant light can better illuminate all areas of the plant and not only meet its light supplement needs, but also reduce the waste of electricity and light energy compared to using square led plant lights. However, for large planting areas, the opposite is true. A circular plant light cannot guarantee uniformity in the light at the junction of multiple lights, which can cause errors. In contrast, using square led plant lights and outdoor led grow lights can solve the aforementioned problems.

Plant characteristics for led plant lights

According to the characteristics of the plant, positive plants need especially adequate light during flowering/fruiting/rapid growth stages, and thus, high-power led plant lights are often used to supplement light. If the plants are in the seedling stage and do not require high light intensity, then using a great value led plant light can meet their growth needs.

Plant growth environment for led plant lights

The growth environment for plants varies greatly depending on their species, and differences in light, air, nutrition, humidity, etc. led plant lights should mainly consider what type of light the plant needs and how much it needs, as discussed above. In addition, some small characteristics must also be noted, such as: assuming the plants are grown in hydroponics, the relative humidity in the environment will be higher, which requires the plant light to have a certain waterproof performance to avoid affecting the effectiveness of the led plant light and the lifespan of the fixture itself.

Traditional artificial light sources produce too much heat. By using led supplemental lighting and hydroponic systems, air can be circulated, and excess heat and moisture can be removed. Electricity can be effectively converted into photosynthetically active radiation, which in turn is converted into plant material. Research has shown that using led lighting, like vertical led grow lights, can increase the growth rate and photosynthetic rate of lettuce by more than 20%, indicating that using led lighting in plant factories is feasible.

Research has found that compared to fluorescent lamps, mixed-wavelength led plant lights can significantly promote the growth and development of spinach, carrots, and lettuce and improve morphological indicators. They can also maximize sugar and starch accumulation in sugar beet roots and produce the highest accumulation of betaine in roots. When grown under LEDs with appropriate wavelengths, the stem and leaf anatomy of pepper and perilla plants changed significantly, and as the light intensity increased, plant photosynthesis rates improved. Compound wavelength led lights can lead to an increase in the number of stomata in marigolds and sagebrush.
