Can the Operating Temperature of LEDs Affect Plant Growth?

Regardless of their geographic location, growers can achieve optimum growth and maximum yields by using the best LED grow lights.

Using LED grow lights is a wise decision because they have the power to enhance the results of growing plants indoors. However, what worries most growers is the type of light they should use, and what distance they need to focus on to ensure maximum yields. When growing indoors, what affects plant growth the most is the light distance. Placing the lights too close can harm the potential of the garden as well as change the plant growth. It may lead to stunted growth and poor results.

Follow the lighting distance recommendations from the manufacturer and make appropriate adjustments as your plant grows.

Understanding the Leaf Surface Temperature

Photosynthesis is a process of constant biomechanical reactions. Here, the temperature range is an essential factor. Various metabolic reactions go on in plants regularly, and the leaf surface temperature between 70-90 degrees helps to maximize plant growth. Within these optimal temperatures, the secondary metabolites become better, as well as enhance flavor-boosting compounds, vitamins, and resins. The air in the grow room has a significant effect on the surface temperature of the leaf. When evaporation occurs, the leaves of the stomata open and close, which allows the exchange of gases and maintains a stable leaf surface temperature.

The Heat Emission of the Lights

Dorm Grow LEDs do not waste energy given off as excess heat. When installed, these lights more efficiently regulate the temperature of the growing area. When growing under these lights, the ideal temperature should be about 70-85 degrees, when the lights are turned on. However, when in off periods, the lights will no longer be in use and the temperature will be lower.

The Importance of the Right Light Distance

For photosynthesis, the proper distance between the lights and the plants is essential. When you install G8LED grow lights, this will provide the plants with the right wavelength and ensure maximum flowering and growth. Just like plants grow under sunlight, they will reach out to the light source. When the intensity and the size of the light increases, so should the distance from the plants. Here are the recommended distances:

  • 12-24 inches for G8-240
  • 14-30 inches for G8-450
  • 16-36 inches for G8-600 and G8-900
  • About 12-36 inches for flower boosters

As plants reach and grow towards the source of light, you should raise the light to maintain a fixed distance. When you get to the appropriate height of the plants that you want, keep the light set and let the plants find their own distance to the light source.

Fewer Nutrients

Since these lights photosynthesize more efficiently, the nutrient should be reduced by 30%. Do not overfeed or overwater the plants.

Furthermore, G8 LED grow lights emit less heat so there will be less water evaporation. This means that you should water less frequently as compared to growing with HPS bulbs. Water once every 2- 4 days or when the top 1 inch of the soil is dry.
