Expert Verdict
I have been growing indoor plants, especially orchids for years. Since these plants are very sensitive to light I had to be very careful. I was always in search of a light meter so the plants would not be deprived of light but since almost every light meter with four settings was very expensive I could not get any. At the edge of giving up on the expanse I found this one and it has all the features I wanted. This can detect a higher range of light than I expected and the price point is just right for me. since the day I got it, I am using it and have been using it on my plants. Now I can measure the amount of light my orchids are getting and I have noticed they were getting less light which is why I was not able to get the expected amount of flowers even though I was taking care of every aspect. Now I manage light and since then I have been able to grow perfect orchid trees!

Growing house plants are not easy and they need extra care in everything. I have plenty of houseplants and pretty sensitive ones. I have already tried several light meters since to measure accurate light measurement in my plants. But since I bought this light meter, I started to lose fewer plants and see fewer burned leaves which only indicates the light meter was giving accurate readings! It has proven useful on rainy and on the sunniest days. I just love how easily I can use this and since this is not too heavy I do not feel like carrying a bulk around. This one is handy and the display is super vibrant even in sunlight. I am not really a tech nerd but what I have learned about using this machine in my plants is this can actually have the lowest ranges of light. Using this one in my backyard plants was really easy because of the vibrant display, so if you are someone trying to find a light meter that would give you an accurate reading and has a really vibrant display to work on a sunny day then go for this one without a doubt.

Expert Verdict
I have been into growing bonsai along with orchids for some time. Since I am taking care of the plants it becomes very clear, both of these plants need a limited amount of water and sunlight. This amount cannot be more or less. So I was getting all kinds of meters and machines to measure all of them. But in that phase, I got this meter and was surprised to see that I could use it for all of the things and I was going to save a lot of cash too! I use this to measure the moisture of the soil, temperature, and sunlight. Since it is detrimental for the orchid and bonsai to bear too much moisture and sunlight I was relieved to have this mad measure every bit that goes into my plants. They are growing very well with measured care and love. I move the plants whenever see too much light on them and also when there is too little. If you need a complete gardening tool for any kind of plants, trees, or anything this is the one you should get.

I love the light meter so much just because of the removable sensor. I can easily get the readings of my plants from a distance. I use a selfie stick to hold the sensor and hold it on top of my plants to get t reading from every corner. This way I get the most accurate reading since no shadow is getting in the way. Usually, other light meters would not get the light readings this accurate because body shadow would often get in the way. Also when I had to get light readings of my backyard plants with their light meters I had to stand in the scorching sun for hours just to get light readings accurately but now I can stand under an umbrella and get light readings of my plants. It has an auto-off mode which can be irritating for some people but I think it actually saves battery and gives you flexibility to use the meter for a longer time. Overall I think this is the best one so far I have used. This might be a little difficult for beginners but worth the hassle.

How To Measure Light For Indoor Plants?
Indoor plants are very fun to grow and for those who do not have access to a backyard but have a passion for growing plants, it is the only option. In growing indoor plants, the most difficult aspect is getting enough light. It is not easy to maintain enough light when growing indoor plants. to solve the problem of light for indoor plants you can measure the amount of light your plants are getting and put them in another place if the measurement is not right. To measure the amount of light:
- You can eyeball the measurements of light for your plants. put the plants in an area where it can get light for at least half the day. Also, you should be cautious of giving too much light to your plants.
- The eyeballing method is not always right and might not work well for sensitive plants. in that, you can use a light meter for accurate readings.
- Use a light meter that can give accurate results.
- Remove the top cover.
- Angle the sensor toward the light not on the direction of your plants. hold the light meter for some time. You will get results in Lux or FC.
So there you can easily measure light for your indoor plants with light meters or sometimes it is possible to eyeball it.
Why We Need To Use Light Meter For Houseplants?
Houseplants tend to be very sensitive to conditions. Especially they need a proper amount of light and water not too much not too less. To grow these plants, it is very important to make sure to always take measurements and give the proper care. This measuring can only be taken by meters. Because houseplants cannot grow in too much light or too little light, light meters come to the rescue here. Li9ght meters are just a handy way to take measurements of the light the plants are getting and if they are not getting enough, you can always move to the light parts of your house. People might think why not just eyeball it, it is not always possible to eyeball light, especially for the sensitive ones. This is why we need light meters for houseplants.
FAQs
Yes, plant light meters work to measure the amount of light your plants are getting. You can measure them and change the position of your plants if needed. Since light is a very important component for plants it is necessary they get enough of it.
Lux is a universally used measure for getting the level of brightness or visible light on the other hand PPFD refers to the amount of light suitable for active photosynthesis of the plants. PPFD tells how much usable light per second reaches your plant. Lux is very casual and what we would refer to as brightness.
Yes, PPFD changes as the distance changes from the plant. All forms of light footprints change as the distance changes from the plant canopy.
All plants have a maximum amount of PPFD range and if somehow they surpass the maximum range your plant is going to face damage. Also, damage can occur if you exceed the maximum level of PPFD in your plant, leaf burn and health problems can occur at this rate.
Final thoughts
Growing plants are very fun and tough at the same time. If the measurements are not right and the plants are not getting enough of every component they start to struggle and all the care that you give to the plants goes in vain. Specially houseplants and the ones like orchids, and bonsai are very prone to getting completely ruined if not given enough sunlight. A light meter can put you at ease and help grow plants that are very tricky. Overall, I personally liked the Dr. Meter LX1330B Digital Illuminance Light Meter because it was both accurate and helped my plants grow in optimal conditions! I hope that you find the light meter that you are looking for your plants.
