Are Himalayan Salt Lamps good for plants?

Himalayan salt lamps have become increasingly popular in many homes (mine included). They give off the most warming pink glow that positively fills the air and cuts through the darkness. And while I absolutely love the feeling of having a salt lamp in my room, I started to question the effect they had on my shrubbery. This led me to search whether Himalayan salt lamps are good for plants.

There is no evidence that Himalayan Salt Lamps are harmful to plants. In fact, many users recommend having both plants and a Himalayan Salt Lamp in your home. It is thought that both can help purify the air in your home and also contribute to creating a relaxing mood and calming atmosphere. While they do seem to produce some levels of negative ions, it’s nowhere near enough to be harmful to plants

How Could Himalayan Salt Lamps Affect Plants?

In theory, a Himalayan Salt Lamp will emit negative ions into the air. Negative ions are responsible for the boost we get to our mood when we walk by the sea or flowing water. A salt lamp is thought to create that feeling in your own home.  These negative ions could be thought to have an effect on plants.

Very little research has been carried out into the effects of Himalayan Salt Lamps. The few tests that have been done suggest that the quantity of negative ions released by a salt lamp is quite low. Consequently, the lamp in your home would not affect your plants.

The only likely effect is that the salt lamp might draw some moisture from the air around it. By keeping a space between the lamp and any plants, and also making sure the plants are kept watered, then this will not be a problem for you.

Are Himalayan Salt Lamps toxic?

Himalayan Salt Lamps are not toxic and do not emit any harmful chemicals or substances. Salt lamps are generally very safe. The salt used to create a salt lamp is a natural product and it is the same salt as you can use in cooking. Therefore, you can rest assured that you will not be harmed by using a salt lamp in your home.

The warm glow that a salt lamp emits is great for creating a wonderful ambiance. Depending on the color of the salt the light can range from pink to orange. However, the light isn’t so bright that I would cause any kind of glare.

Claims are made that having a Himalayan Salt Lamp glowing in your bedroom can help you fall asleep naturally. It will also improve the quality of your sleep. Computer screens, cell phones and the like emit a disturbing blue light. Using a salt lamp to introduce a calming glow is an excellent idea. Switch you other screens off first to give your brain a chance to calm itself.

Can salt harm plants?

Yes. Salt is one of the most harmful substances to plants. Plants growing outdoors generally will not suffer damage from salt accidentally. The greatest risk of salt damage comes in winter months when salt is sprayed onto roads to help clear ice and snow. 

Salt spray will cause salt burn on roadside plants. It will also cause the outer layers of natural protection on buds, stems and branches to wither, and the exposed plant can then die from wind chill. Usually trees and hardy shrubs will recover, but other more vulnerable plants can be killed completely.

The salt being sprayed only partly lands on the road. Much of it will be absorbed by the soil along the roadside, and this will affect the soil quality. Salt impregnated soil will lead to poor plant growth and water runoff. 

Indoor plants are unlikely to be accidentally harmed by salt, unless in the most unusual circumstances. However, if you own a Himalayan Salt Lamp, do not allow your plants to come into contact with its surface. Leaves that touch the lamp will begin to turn brown and die back. The plant itself will cease to thrive. 

Take care, also, not to water your plants with salt water. The salt in the water will draw moisture from the roots of your plants and they will dry out. There is also a risk, if the concentration of salt in the water is very high, of salt poisoning which will kill your plant.

If you have indoor plants that seem to be suffering from salt damage and you don’t know why then check your water softener. A faulty water softener might be the cause of the problem.

Does artificial light harm plants?

Artificial light will not harm plants. If you grow plants indoors, then artificial light is an essential source of light for them. Check out one of my favorite artificial lights for plants on Amazon.

All plants need light to enable them to photosynthesize. Photosynthesis is the process by which plants convert light into energy. All plants need light if they are to grow properly and thrive.

Most of us who have indoor plants grow them on a windowsill. Here, they will get sufficient light from outside. That light is natural and follows the daily rhythm that outdoor plants follow.

If, however, you have your indoor plants growing away from a window or other source of natural outside light, they will need special attention. A normal domestic light bulb will not produce the intensity of light that plants need. You will need to provide some specific artificial light for your plants.

8 Tips To Heal Your Soul

Artificial light cannot replace sunlight, but it does have a few advantages when growing indoor plants. Firstly, you can choose the best light source for the type of plants you are growing. Secondly, you can position your light source wherever you need it. Thirdly, you can create artificial daytime and night-time. 

All plants need a period of darkness each day to enable them to rest. Imagine having to work hard 24 hours a day with no break. Plants are the same. They need time to take a break from photosynthesis. The plants will reward you by being healthier and thriving.

The glow from a Himalayan Salt Lamp is not sufficient light for any plants. Use it to create a homely atmosphere, not as a light source for your indoor plants.


There has been very little research carried out into the benefits of Himalayan Salt Lamps. Most of the claims made for them come from anecdotal evidence. Have one or more in your home if you love their look and the relaxing glow you get from them. Don’t rely on them for health benefits or to benefit your plants. Generally speaking, these salt lamps are harmless to humans and to plants.
