What precautions should be taken when using plant grow lights?

Growing lights, as a substitute for sunlight, can provide plants with light anytime, anywhere, and their use in agricultural planting has increased significantly in recent years. Whether in greenhouse cultivation, home gardening, or plant factories, growing lights can be used. However, the following three points must be noted when using growing lights; simply adding supplemental light to plants is not enough.


1. Pay attention to adjusting the distance and position of the growing light.


If the growing light is only for supplemental lighting, it can be placed slightly closer to the plant. If the growing light also has a heating effect, it should be placed further away to prevent damage to the plant.


Generally, it is recommended that the top of the plant be 0.5m-1m away from the LED growing light. This distance not only allows the plant to receive sufficient light, but also allows the LED growing light to illuminate a wider area. At the same time, the height of the LED growing light should be adjusted appropriately according to the plant's growth rate to control the LED growing light in the most suitable supplemental lighting position.


2. Pay attention to the intensity of supplemental light on the plant.


Avoid using growing lights immediately after transplanting crops. Wait until the plant has recovered and is growing normally before using growing lights. Supplemental lighting for plants should be flexibly adjusted based on the plant species and different growth stages of the crop. The level of supplemental light required by plants varies at different growth stages. During germination and seedling stages, the light requirements are not very strong, so the distance between the plant lights and the LED plant lights can be increased to avoid wasting electricity. When plants are flowering and fruiting, the light requirements increase, and at this time, LED plant grow lights should be used to supplement the plants according to the optimal lighting plan.


3. Do not supplement light 24 hours a day. Plants are living organisms and need rest. It is also very important to reasonably control the time spent supplementing plants with LED plant lights. Generally, it should not exceed 16 hours. Plants also need time to rest and respire. Depending on the weather conditions, if there is sufficient sunlight during the day, supplemental lighting can be provided for 2-3 hours in the morning or evening. If there is insufficient sunlight for a long period of time due to cloudy, rainy, or foggy weather, supplemental lighting should be used for a longer period. According to the crop's habits, do not provide prolonged supplemental lighting for non-light-loving plants during stages when supplemental lighting is not recommended.


Founded in 1998, Luxgrow focuses on the research and development and manufacturing of light technology applications. In the field of plant lighting and artificial light vertical planting solutions, Luxgrow utilizes LED light-emitting technology based on the solar spectrum, precisely targeting the wavelengths required for plant growth, eliminating useless light, and producing a variety of LED plant light products.


1. Luxgrow Small Leaf LED Plant Light: Luxgrow's small leaf LED plant light uses a specialized plant spectrum, with a reasonable ratio from 380nm to 800nm, meeting the physiological needs of plants and completely replacing natural light.


Suitable for supplemental lighting of succulents and small flowers, preventing excessive growth, promoting a beautiful plant shape, maintaining vibrant flower colors, and extending the flowering period; also suitable for supplemental lighting of indoor foliage plants, resulting in healthier leaf color, more compact plant shape, and thicker leaves. It can be used in offices, rooms, corridors, etc., as supplemental lighting, at any time of day, whether day or night, cloudy or rainy, indoors or outdoors, extending the duration of light, increasing light intensity, and promoting plant growth and development.


2. Guangmingyuan LED Plant Supplement Lights

Based on the solar spectrum, Guangmingyuan LED plant supplement lights utilize LED light-emitting technology, precisely targeting the wavelengths needed for plant growth, eliminating useless light. Customized plant spectra are tailored to the different growth habits of various plants, providing them with sunlight-like illumination and significantly improving the efficiency of photosynthesis.


Three dimming levels and three functions are available. The customized plant spectrum, ranging from 280nm to 800nm, is rationally proportioned to adapt to different environments, providing plants with an ideal light environment for photosynthesis and promoting growth at different stages.


Can be used at any time of day, whether day or night, cloudy or rainy, indoors or outdoors, extending the duration of light, increasing light intensity, and promoting plant growth and development. Click the image to purchase directly.


3. Guangmingyuan LED Plant Flowering Lights

Flowering lights are suitable for long-day flowers. Applied to long-day flower varieties with long flowering periods, they induce flowering, prolong the flowering period, and enhance the ornamental value of indoor plants.


Guangmingyuan's plant-specific flowering light uses an LED filament lamp light source design for efficient energy conversion. Its high-transparency glass cover ensures good light transmission, safety, and energy saving.


Utilizing a specialized plant spectrum that balances growth benefits with human visual comfort, the bulb's radiation spectrum meets the physiological requirements of plants, completely replacing natural light. This better regulates flowering time, advancing and extending it, and improving fruit quality and color.
