What Need to be Paid Attention to When Using LED Grow Lights ?

Light is a crucial factor in the development of quality crops. If crops can be given the adequate and consistent light they need, they will automatically optimize their performance and show higher quality during the growth process. led grow lights are is the kind of device.

LED grow lights have some convincing advantages,allowing growers an opportunity to benefit from this unique and powerful lighting system. they are

• They use less electricity, allowing you to save money over time.
• They also emit less heat, which can be a great advantage, not only suitable for large planting spaces, but also for small grow setups .
• They can be paired with diverse spectra. for growers , they have many options.
• They will become more and more advanced and affordable as the tech has become widespread.

However , here are some mistakes novice growers or those who are new to the field of led grow light may make. it is probably due to the lacking of in-depth knowledge. Yet these mistakes are not inevitable. Knowing what mistakes other growers have made will help you recognize them and avoid them or learn from them.

 To help those who are new to the field of led grow lights get a rough idea of plant lamps, here are some of the more mature applications of led grow lights. Let's learn about it together.

 ① led grow light for cannabis cultivation.       ② led interlight for greenhouse vine crops (tomatoes and cucumber)

③ led grow light for vertical hydroponic tower.      ④  led grow light extend daylight for floriculture

⑤  led grow light for cannabis clone and microgreen growth .   ⑥  led grow light for leafy green vertical farming

Now let's look at the mistakes that some growers have made 

1) Pay attention to the distance between LED grow lights and crops 

LED grow light has only been used in crop cultivation for a very short time, just a few years. So in the specific application of LED lights, many early adopters are copying the usage of traditional plant lamps such as MH, HID and HPS. However, they overlooked the inherent characteristics of LED grow lights themselves-less heat dissipation. This led them to install led grow lights too high. Because of the excessive installation height , the crops have to force themselves to stretch upward in order to get enough light , resulting in spindly , emaciated growth.

In terms of the installation height of led grow lights,it is best to finalize the installation height in conjunction with the measurement of the PAR meter. Through the measuring, the grower can roughly know the photosynthetically available radiation（PAR）value at the top of the crop.

2) check the light spectrum suitable or not

Either as a supplementary light source or as a substitute for sunlight,the purpose of using led grow lights is to allow crops to better and more fully photosynthesize.Only when plants receive enough of colour light photons they need , and then they will photosynthesize fully. Different kinds of crops, their preference for light photons is not the same. Before using led grow lights, including when choosing them,spectrum should be one of the key factors to pay attention to.

It seems like a not bad idea to provide crops with a variety of colour photons of equal weight when in doubt as to which color photons a crop prefers. However, such blind lighting supply has a big and obvious disadvantage, that is the waste of energy.  so it is better to design and tailor the lighting spectrum,make it just enough.

Check the lighting spectrum,it is vital. If you don't choose the right spectrum for your crops, all the inputs will yield little or nothing.Checking the spectrum of led grow light you have selected should start from the following aspects.

• What colour of light do plants absorb?
• The effect of different colour light on plant growth.
• Studying the plant you want to grow in depth,include the life cycle, the different growing phases, the final harvested product, etc.
• Compare your crops and make a prediction of the spectrum provided.
• Take advice from professionals

3)  light schedule for different crops or in different grow phases.

Even if you choose the right led grow light product and install it at the right height, if you don't schedule the lighting time moderately （keep on too long or too short）for your plants, all your previous efforts may also fall apart.

A common mistake made by previous growers was that they assumed that giving plants 24 hours of light a day would allow crops to grow as fast as they can, and thus increase the number of harvest times in a year, but It's not. As a matter of fact ,plants need a light-dark cycle to develop properly. 

So when using led grow light indoors, pay attention to the lighting schedule. For example, when you cultivate cannabis indoors,it is necessary to arrange the illumination time as reasonably as possible after selecting led grow lights suitable for cannabis cultivation.
