The Most Important Tips for Grow Lights

Best way to select a suitable Grow lights

 

Everyone knows that plant growth requires photosynthesis. If there is a lack of sunlight, plants will wither or grow slowly, which will affect plant growth, germination, flowering, and fruiting. Therefore, light is very important for plant growth. Without light, plants will shrink or their growth cycle will become longer, resulting in poor growth.
The following are some suggestions for buying plant grow lights, which are also your doubts about plant grow lights before buying them. hope the following information can help you out:

1. Can plant grow lights replace sunlight?
When We are buying plant grow lights,The sales representative will say that this product is full spectrum. Full-spectrum means lamps made by imitating the spectrum of sunlight, but in fact, these full-spectrum grow lights are visible light with wavelengths between 380nm and 780nm and do not include ultraviolet and infrared. The spectrum of real sunlight includes ultraviolet and infrared. Plant growth also requires a small amount of ultraviolet and infrared. Therefore, the full-spectrum function of plant growth lights is not entirely the spectrum of real sunlight. Therefore, the plant growth light is a supplement when the indoor sunlight is insufficient, so the plant growth light solves the problem of insufficient light during the growth of plants.

2. Why are the plant growth lights are often seen red, blue, or orange?
Different plant growth lamps emit different spectra, and the spectra of different brands and models are also different, and there are many varieties, but the common feature of plant lamps is that blue light and red light account for the largest proportion. This is because the wavelength of blue light is 400nm to 470nm, which can stimulate the growth of seedlings, the growth of leaves and roots of plants. The wavelength of red light is 630nm to 660nm, which can stimulate seed germination and plant flowering and fruiting. The wavelengths required in different growth stages of plants are also uneven, so we need to choose the plant light that suits us according to our actual situation and plant species. More blue light? Is that less red? Buy according to the different growth stages of plants, or buy a plant light with mixed wavelengths.

3. Can ordinary lamps replace plant grow lights?
Ordinary lamps cannot replace plant grow lights. Because the fluorescent lamp emits a lot of heat, it will burn the plant, and the LED lamp generates very little heat and will not burn the plant, but the ordinary LED lamp is only for lighting. The spectrum of the LED lamp has white light, red light, and blue light. The red light and blue light, so ordinary LED lights are not suitable for plants to grow lights. It is very important to buy professional plant grow lights because the professional plant grows lights will be equipped with enough red or blue light, which will better stimulate plants’ growth potential and be suitable for different plant growth stages. Including the growth of seedlings, various green leafy plants, vegetables, fruits, succulents, etc…

4. The distance between the plant growth light and the plant.
Generally, the distance between the plant grow lamp and the plant is 40~75 cm. The closer the lamp is, the greater the intensity, the better the photosynthesis effect. There is very important data. PAR (Photosynthetically Active Radiation), is the efficiency of how much light a plant can absorb by photosynthesis in the visible light range. Some lamps use PPFD (Photosynthetic light quantum flux density) instead of PAR. In short, the higher the two data of PAR and PPFD, the better. If a plant needs a lot of light, this value will be higher, and the distance to the plant will be closed. If it is a small seedling or a general green leaf plant that does not require much luminosity, the plant light can be hung farther, so when you buy the light, you need to look at these two data. The larger the data, the light intensity can be adjusted flexibly.

In general, we should pay attention to two points when choosing a plant to grow lights:
1>The color of the spectrum can be mainly blue or red or add a little more yellow-green, it will look more comfortable.
2> PAR. and PPFD values. The higher the effect, the better.
