How to Use a Light Meter for Indoor Plants?
If you want to keep your indoor plants healthy and thriving, then you need to make sure they are getting the right amount of light. But how can you tell how much light your plants are getting? One way is to use a light meter. In this blog post, we will teach you how to use a light meter for indoor plants, and give you some tips on how to get the most out of your plants!
Hold the light meter as close to the leaves of the plant as possible, with the sensor pointed away from the plant, in the direction of the incoming light.

What is a light meter and what does it do?
A light meter is a device that measures the amount of light in a given area. It is usually used by photographers to determine how much light they need to properly expose their film or digital sensor. But light meters can also be used for other purposes, like measuring the amount of light your indoor plants are getting!

How to use a light meter to measure the amount of light your indoor plants need?
To use a light meter to measure the amount of light your plants are getting, simply hold the sensor close to the leaves of the plant, with the sensor pointing away from the plant and in the direction of incoming light. The reading on the display will tell you how much light is reaching that spot. Keep in mind that different plants need different amounts of light, so you will need to consult a plant care guide to determine how much light your particular plant needs.
Tips for using a light meter to get the most out of your plants?
Here are some tips for using a light meter to get the most out of your indoor plants:
- Place the light meter sensor close to the leaves of the plant, but not touching them.
- Point the sensor in the direction of incoming light.
- Take multiple readings throughout the day to get an accurate idea of how much light your plants are getting.
How do you use a light meter for lighting?
In addition to measuring the amount of light reaching your plants, you can also use a light meter to help you adjust the lighting in your home. If you find that your plants are not getting enough light, you can use a light meter to determine how much light you need to add. You can do this by holding the sensor in the spot where you want to add light, and then adjusting the lamps or other light sources until you get the desired reading on the display.
How do you tell if a room has a enough light for plant?
If you’re not sure whether a particular room in your home has enough light for plants, simply set up a light meter in the room and take a reading. If the reading is below the minimum amount of light required for your plant, then you will need to either add more lighting or move your plant to a brighter location.
Do light meter apps work for plants?
Yes, light meter apps work for plants! Just open the app and hold it close to your plant leaves in the same way you would use a regular light meter.
LUX vs PAR Meter
PAR meters measure the amount of light that is available for photosynthesis, while LUX meters measure the amount of light that is visible to the human eye. While both types of meters can be used to measure the amount of light reaching your plants, we recommend using a PAR meter for best results.
There are many different PAR meters on the market, but our favorite is the Apogee MQ-500 Full Spectrum Quantum Sensor. This meter measures not only PAR, but also UV-A and UV-B light, which can be beneficial for some plants.
No matter which type of meter you use, taking multiple readings throughout the day will give you the most accurate idea of how much light your plants are getting.
PAR Meter vs Footcandle Meter
Footcandle meters measure the amount of light that is reaching a surface, while PAR meters measure the amount of light that is available for photosynthesis. While both types of meters can be used to measure the amount of light reaching your plants, we recommend using a PAR meter for best results.
