There is no doubt that led grow lights have numerous benefits, but still, there are many people who are confused about their safe use. If you are one of them who are concerned about whether these grow lights are safe for humans or not, you are not alone; it’s often asked many times.

Overexposure to any light, even natural Sunlight can be dangerous. That’s why people use protective gear or sunscreen lotions when they are exposed to sunlight for long hours.

In this following article, we will clear all your doubts and answer most of the questions that arise for the safe use of LED Grow lights.

Do LED Grow Light produce UV rays?

The wavelength of light rays that are not visible to human eyes and are below the wavelength of the visible spectrum are harmful. UV rays and other radiations having lesser wavelengths are dangerous for humans.
UV rays can be further classified into three different types as UVB, UVA, and UVC.

Among these three, UVC has the shortest wavelength and is regarded as the most dangerous ones.

In the process of photosynthesis, plants do not require UV rays but their presence of offers some advantages. The major benefits of UV rays for plants are protection from pests, quicker photosynthesis, and better yield results with high nutrients.

In short, LED grow light emits UV rays that offer more benefits to commercial gardeners.

Are LED Grow Lights & tent kits dangerous for humans?

To answer this question, we would like to ask another question about the devices you are using on daily basis.

Do you think Smartphone/Laptop screens poses danger to humans?

The most common answer would be Yes. We know that Smartphones or Laptop screens emit blue radiation harmful to human eyes, but does that mean we should stop using them?
Of course not! We just need to regularize our daily hours or can use blue rays’ protective glasses to protect our eyesight.

In the same way, LED grow lights also emit harmful rays, just like the sunlight or any other electronic device but we just need to take preventive measures.

Following are the preventive measures you should take while working under LED grow lights

  • Wear horticultural eyewear to protect your eyes.
    There are protective glasses designed exclusively for use with LED grow lights to protect your eyes. They are inexpensive and unlike sunglasses, they won’t infringe your vision. As a result, they allow you to view your plants naturally in their true colors.
  • Don’t stare at lights continuously
    If you are using the fixture of LED grow lights with a lot of blue and UV diodes, avoid staring at them directly to protect yourself from the powerful light intensity.
  • Wear full-body clothes
    The commercial growers or passionate gardeners should wear full sleeves clothes or protective dresses to cover most of their body parts and need to control the time they spend while working under these grow lights.

Conclusion

LED grow lights are way safer as compared to other high-intensity grow lights like HPS. However, there are still some risks and cautions, which can be easily overcome if handled with care. So, keep all things mentioned above in mind and stay fully safe.

  1. Do these UV rays pre-acclimate plants to regular sunlight or do I still need to slowly get my indoor Spider-Farmer grown plants used to direct contact from full sunlight when moving them to a full-sun garden?

      Don’t hold me to it, but I had no issues going directly outside from starting inside using an SF1000 and SF2000

      It depends on the temperature and light intensity outside. For example, I live in San Antonio and the temperature/ light intensity is much higher outside, so I have to harden my plants before transplanting them. If you’re in a more mild environment I think you can get away with a direct transplant. To be on the side of caution, I would leave them outside for a day if they can make it that long without overstressing, if they’re happy then you’re good to go. Happy Growing 🙂
