How Do I Know My Grow lights Are Harming My Plants?

This is a first-time grower. I received my friend's old grow lights. They are square panels with bottom-mounted blue and red LEDs. The issue I'm having is that they have absolutely no labels, thus I have no idea how effective they are. How can I tell whether these lights are damaging my plants?

To protect your plants from further harm, it’s critical to take prompt action if you see any of these symptoms.

  • The leaves are fading to brown or yellow. Your crops need light to produce chlorophyll, which gives leaves their green hue. The plant isn’t getting enough light if the leaves are becoming brown or yellow.
  • The leaves are scorched. The plants are exposed to too much light if they are crunchy or browned. This is a strong hint that you should move your plant farther from the light.
  • The plant is elongated. If your plants are taller than normal and have more space between their leaves, it suggests your plant is receiving too much blue light.
  • The plant is withered. This could indicate a number of various issues, but one issue that could be accentuated is that the roots are not receiving enough oxygen probably due to the close distance between the plant and the lighting.
  • The plant isn’t growing. This can indicate that your crops aren’t receiving enough light or that the light spectrum isn’t correct.
