Quick Answer: Why Are LED Grow Lights Purple?

Quick Answer: Why Are LED Grow Lights Purple?

Purple and violet lights have short wavelengths and thus lots of energy.

Green light is the least effective for plants because they are themselves green due to the pigment Chlorophyll.

Different color light helps plants achieve different goals as well.

Blue light, for example, helps encourage vegetative leaf growth.

Can LED grow lights damage your eyes?

There is a myth that LED lights harm our eyes and even can cause blindness. Of course, if you stare directly at a LED bulb for hours, they, just as any other artificial light source, will be harmful to your eyes. But if you use LEDs normally, they are completely safe.

Are LED grow lights harmful to humans?

Most wavelengths are not harmful. However, LED grow lights that put out ultraviolet light are harmful to your eyes. This includes but isn’t limited to fluorescent LED grow lights, HPS grow lights and metal halide grow lights. Any blue light could emit ultraviolet light.

Why does red light help plants grow?

The fact that leaves don’t usually appear blue or red means that they absorb those parts of the light spectrum and use them to grow. The effect of blue light on plants is directly related to chlorophyll production. Red light is responsible for making plants flower and produce fruit.

Can any LED light be used as a grow light?

If you’re using regular incandescent lights, you’re not very likely to grow strong and healthy plants. Therefore, for best results it is recommended that you use full spectrum LED grow lights. They are specifically designed for the purpose and have the feature to deliver light in the exact spectrum the plant needs.

Is LED grow lights any good?

LED Grow lights produce very little heat, which for many is an advantage. However, those growing with LED’s in colder indoor areas may need to supplement the extra heat an HID light such as an HPS or MH would produce.

Can LED grow lights cause cancer?

Research indicates that LED lights do cause cancer. They also seem to cause blindness by causing permanent damage to the retina. By the way, it turns out that the CFL bulbs are better than LED ones but still have UV radiation. UV radiation can be harmful to the skin and to the eyes.

Are LED lights dangerous for eyes?

Spanish research has shown that blue LED light can irreparably damage the cells in the eye’s retina. Eco-friendly LED lights may damage your eyes, according to new research.A study has discovered that exposure to LED lights can cause irreparable harm to the retina of the human eye.

Are LED grow lights bad for your skin?

For intensity, lights capable of growing good plants will contain enough energy to damage your eyes. Any light source that emits UV (fluorescent, metal halide, HPS) will have a higher potential for harming people than those that do not (MOST LED fixtures, but not all).

How long do LED Grow Lights last?

Most LED lights have an expected lifespan rated at somewhere between 50,000 and 100,000 hours of use. In comparison, many other grow lights tend to last for around 20,000 hours before needing to be replaced.

What color LED grow light is best?

The Best Color Spectrum for LED Grow Lights

What is the best color spectrum for LED lights? It should be close to the spectra used by plants. Lots of blue and red, and some green and yellow. Add some near IR and maybe even near UV and it is even better.

Do red and blue LED grow lights work?

Not any red and blue LED light will work. If both colors are present in one light it is likely a grow light so yes, it will work because red and blue are the two colors responsible for photosynthesis.

Should grow lights be on all the time?

As a general rule of thumb, most vegetables and flowering plants need 12 to 16 hours of light per day, with flowering plants at the top end of that range. Plan on giving most plants at least 8 hours of darkness per day.

How many LED grow lights do I need?

Plants and especially cannabis need most lighting during the flowering stage, so we`ll be using that as an estimate of how much area needs to be covered. A standard LED grow light must use more than 32 watts per square foot of grow space, but for optimum results it should be over 50 watts, up to 80 watts.

Can I use normal LED light to grow plants indoor?

All plants can use artificial light. You can’t use the normal LED light to grow plants indoor (But, if this normal LED light’s lighting source is a full spectrum LED, maybe you can have a try. Check it is a full spectrum LED light or not, first). Any how, the grow light always the best choice for your plant.

Can any LED light be used to grow plants?

Horticultural LED grow-lights produce only the wavelengths most utilized by plants, so you may want to look for these bulbs rather than buying ones for general use. Halogen lights can also provide full-spectrum light, but like incandescents they put off a lot of heat and are less energy-efficient than fluorescents.
