A comprehensive trial and error process, as well as thorough research and testing, helped me choose the best grow lights for indoor plants. Each and every one of these best grow lights were carefully selected and measured to make sure that they are strong enough to keep your plants not just alive but healthy and beautiful.

And I’m so happy I can recommend to you these products that will help your indoor plants live their best life.

Research

Why You Should Trust Mr. Houseplant

I have been growing house plants for over 10 years. I have been growing house plants under full spectrum LED lights for over 6 years. This allowed me to learn about different types of grow lights, how to measure their intensity, how to determine the proper distance between the light and the plant, and other intricacies of growing indoor plants under grow lights. I owned a venus flytrap production business for several years. And during that time, I grew venus flytraps under fluorescent lights, which helped me significantly expand my knowledge about grow lights.

During my houseplant career, I had the opportunity to use and test many different brands of full spectrum LED lights – Rousseau, Sansi, GE, Soltech Solutions, Spider Farmer, and many other well-known and less-known grow lights.

I compiled the list of the Top 5 Best Indoor Plant Lights based on my personal tests of the products, my personal experience with grow lights, and the feedback of my community of over half a million people that follow me on social media.

How Mr. Houseplant Selected And Tested Products

I identified the key decision making factors for grow lights and tested 15 grow lights to see how they measure for each of the factors. The key decision making factors were: 1) grow light intensity 2) design 3) price 4) coverage area 5) glare 6) features that set it apart from the competition and 7) warranty

I tested 15 grow lights with a PAR meter (a grow light meter) at different distances to determine the full spectrum light intensity and the coverage area, and how well the lights keep their intensity at different distances. I checked whether the grow lights produce a glare. I’ve had these grow lights for over 3 years and have been using them every single day on my houseplants. I tested how different indoor plants react to each of these lights, at different distances, after exposure of several weeks to several months. I also looked whether the grow lights have features that set them apart from the competition.

Based on the key decision making factors previously mentioned, I determined the top 5 best indoor plant lights.

Please note that using a PAR meter (a grow light meter) is the only reliable way to test grow lights.

PROS

CONS

  1. It has a great design which goes well with any interior. This is particularly important and beneficial because there aren’t many high-quality grow lights that look good and don’t make your home look like a nursery.
  2. It’s 4000K full-spectrum light which means it’s not a purple light but contains enough blue light and red light to successfully imitate natural sunlight.
  3. You can grow full-sun plants underneath this grow light, it’s that strong.
  4. You can buy it with or without a timer.
  5. You can adjust the angle of the beam (which is not possible with its competitor Soltech Solutions), so the light can be either more focused and stronger if you’re growing only one plant under it, or you can make the angle wider, so it covers a larger area. Also, it doesn’t have a glare, while Soltech Solutions does have a bit.
  6. If you’re from the U.S, by buying this light you would be supporting a small U.S. business.
  7. Different colors are available; it comes in white and black.
  8. There is no glare from this full spectrum LED light, which is a common issue with some of the best grow lights.
  9. And the last, but not least important, you can get 15% off by using the code MRHOUSE15 at checkout.
  1. It’s not the most affordable light but is still cheaper than a lot of bigger lights.
  2. The area it covers is relatively small, so It’s only good for growing one larger plant or a few small ones.

PROS

CONS

  1. It’s a grow bulb, not a standalone grow light, so you can use it with most floor or desk lamps.
  2. Very strong, you can grow full-sun plants underneath it or tropicals.
  3. It’s full-spectrum light, with sufficient blue light and red light to imitate the sun.
  4. Doesn’t have a glare, the way the Sansi 36W bulb does, because the beam is more focused. This is why it provides a stronger light than Sansi 36W.
  5. Excellent for smaller-sized plants, tropicals, and succulents.
  1. It covers a slightly smaller area than Sansi 36W, but as Sansi, the area it covers is relatively small, so It’s only good for growing one larger plant or a few small ones
  2. It has a hint of a purple in the light, which can be seen in the shadows that the light makes. It’s not a big deal, doesn’t make a difference in growing plants indoors, nor a big difference in ambiance.

Why Are Grow Lights So Important

As a plant lover, you already know that light is plant food and that plants cannot live, let alone thrive without it. The more light you provide, the happier and healthier your plants will be. More light provided by grow lights helps your plants to photosynthesize more, grow faster, and produce bigger leaves and more sugars for their development.

The good thing is that you can achieve the equivalent of bright indirect light or even direct sun with grow lights if you’re not lucky enough to have large windows with an unobstructed view of the sky, especially if you use good, tested grow lights.

To get great results with best grow lights for indoor plants, you need to be aware of the importance of selecting a good grow light that produces enough light of sufficient intensity to keep your plants alive. I see people buying lights that are very weak and only useful at very close distances of 2 to 4 inches away from the plant.

Measuring an indoor plant light requires a relatively expensive device called a PAR meter. The price of a PAR meter is usually around 500 USD or more. But you can occasionally find a more affordable PAR meter.

To save you from the hassle of buying a PAR meter and learning how to test grow lights, I tested dozens of different indoor plant lights and selected the best ones for you.

What Are Indoor Plant Lights Used For

Grow lights are used by both houseplant lovers and professional plant nurseries for supplementing natural light or fully replacing it, for growing plants of good quality and plant propagation. These lights stimulate photosynthesis and provide the right color spectrum for the plants to grow and thrive.

Whether you will use grow lights depends on the amount of natural light available in an apartment you live in and your plant’s needs for light.

If you grow plants in an apartment that has small windows or north-facing windows (if you’re living in the northern hemisphere), or in a basement apartment with minimum or no light for most of the day, you will need to use an indoor plant light to supplement or fully replace natural light. If you’re living in the southern hemisphere (South America, Australia, part of Africa) and have south-facing windows, they receive the least amount of light, so in that case, you might need to consider grow lights.

Seasonal changes and not enough light during wintertime can also nudge you to use grow lights to supplement the amount of light your houseplants usually receive during other seasons.

Best Grow Lights for Indoor Plants

I love using indoor plant lights and I use several kinds for my indoor jungle. But the fact is I didn’t nail the best ones right away. A comprehensive trial and error process, as well as independent research and testing, helped me choose the best grow lights for indoor plants. And I’m so happy I can recommend to you these products that will help your indoor plants live their best life.

Each and every one of these grow lights were carefully selected and measured to make sure that they are strong enough to keep your plants not just alive but healthy and beautiful. I measured their intensity with a PAR meter (a light meter that measures light useful for plants, light between 400 and 700 um). I have also been using these grow lights on my houseplants for a while, and some of them for several years.
