How to use supplementary lights
An article related to the use of supplementary lights and the correct methods of using them in green plants. The following is a detailed explanation by the editor:
Supplementary lights can compensate for the insufficient light for plants. Reasonable supplementation can enhance photosynthesis and promote plant growth. Supplementary lights essentially replace sunlight. By turning them on, we can strengthen photosynthesis and promote plant growth and flowering. Proper use of supplementary lights is very beneficial for plant growth.
Many people buy supplementary lights and don't need them. After using them for a while, the plants show no changes, and they may even blame the poor quality of the lights. In fact, it is because they don't know how to use them. Different brands and prices of supplementary lights have different effects, and the key is the method of use; only proper use brings results.
Buying supplementary lights and simply turning them on is not enough. What plants need from supplementary lights is not brightness, but the illuminance emitted by the lights. Only when the illuminance is suitable will plants perform photosynthesis. If you just turn on the lights randomly and illuminate the balcony, it has no effect.
Firstly, we need to distinguish between the brightness and illuminance of supplementary lights, as these are two different units. Brightness refers to the wattage, where higher wattage means brighter light. Illuminance refers to the intensity of the light emitted through illumination, usually measured in lux, where higher wattage means higher intensity of照射.
How to use supplementary lights
Whether for growing succulents or ordinary plants, supplementary lights must be used properly. Normally, the distance between the lights and the plants should be about 20 to 30 centimeters. For succulents, 20 centimeters is very appropriate, while for ordinary plants, 30 centimeters is suitable. For many leafy plants that also need supplementary lights, the distance should be slightly farther.
If the supplementary lights are closer to the plants, the effect will be better and the intensity of illumination will be higher. Although both are supplementary lights, the effect of placing them 20 centimeters away from the plants compared to 50 centimeters away is completely different. Both can illuminate the balcony, but the results for the plants are different. When the lights are 50 centimeters away, the intensity of the illumination is weaker, and the efficiency of photosynthesis is also reduced.
For home use of supplementary lights, mainly for growing succulents, whether it's light tubes or bulbs, a distance of about 20 centimeters from the succulents is very suitable. Not too far, as a distance that is too far is ineffective for the plants. At 20 centimeters, changes in the plants can be clearly observed within a month.
What plants lack is not brightness but the intensity of light, which everyone must understand. This is like the difference between growing succulents in the south and the north. The south has strong UV radiation, resulting in better succulent growth, while the north has weaker UV radiation, and growing succulents there does not show much change.
The distance between the sun and the plants varies, and thus the results for the plants are completely different.
The above is the complete content on how to use supplementary lights and the correct methods of using them. Green plant enthusiasts might find it useful to refer to this information.
