Keeping plants alive and helping them flourish can be hard as is, but growing things indoors is even more tricky. You have to give them enough—but not too much—water and make sure they have enough soil and a large enough pot. Aside from that, one of the most crucial factors of growing plants inside is light.

Positioning your plants in front of a window where they can drink up natural sunlight is ideal. But as you probably know, this is easier said than done. Whether your window situation is less-than-sufficient for plants or you live somewhere that only gets sunny a few months of the year, a grow light is an excellent solution.

What to Look for in a Grow Light

Size

When deciding what size grow light you need, think about how many plants you'll need to cover. Also, if you’re planning to move your light from place to place, you may want something lighter and portable, whereas if you know it’s going to stay put, that may not be as much of a factor. Also, consider the space where you plan to put it and make sure there’s room for it to operate safely and not up against furniture, drapes, or other items.

Type

There are various types of grow lights to consider, from panels to ones that hang overhead or screw into a regular light fixture. The type of plants you have, the amount of existing natural light, and where your plants are located will help you narrow down your choices.

Ease of use

From installation to keeping them operating properly, some grow lights require more effort than others. Also consider how much noise a grow light makes, particularly if it’s going to be placed in a busy area.

Want to flex your green thumb inside? Here are the best grow lights to help your indoor plants live their best life.

Best Overall: Roleadro LED Full Spectrum Grow Light

Roleadro LED Grow Light, 75W Full Spectrum Grow Lights for Indoor Plants, Plant Light with IR & UV
Very Good

The best overall option is the Roleadro LED Grow Light. Thanks to the brand's proprietary spectrum with 460 to 465 nm, 620 to 740 nm, and a 6,000 to 6,500 K waveband, it provides indoor plants with a diverse range of light. This helps promote growth and allows even the most delicate, tropical plants and flowers to not only grow but bloom year-round. You can also grow seasonal vegetables and herbs in the winter, spring, summer, or fall.

This 75-watt grow light also has an aluminum cooling plate to effectively dissipate heat, even on the highest setting. It comes with hanging brackets and is easy to set up. You can put it together in about a minute and hang it from almost anywhere in your home.

"In our test, the grow light gave our seedlings ample nourishment early on, so they didn’t outpace themselves. The light also proved to be the perfect size for a standard seed tray. It distributes light evenly so each seedling gets an equal share of light."—Stacey L. Nash, Product Tester

Best Bulb: GE Grow Light With Balanced Spectrum Seeds & Greens LED Light Bulb Clear

GE Grow Light LED Bulb

You can also get special bulbs for growing indoor plants, like the GE BR30. This full-spectrum bulb offers high-quality lighting that encourages houseplants, indoor gardens, cacti, and flowers to flourish every month of the year. Unlike some other grow lights that produce harsh lighting, it provides soft, natural illumination and warmth.

The GE BR30 features innovative LED technology, which allows it to last for 25,000 hours (or about five years) and use only 9 watts of energy. With a balanced light spectrum designed for seeds and greens, you can grow herbs, lettuce, cucumbers, peppers, and other vegetables right in your home.

Best LED Bulb: Haus Bright LED Grow Light Bulb Original

The best LED bulb for indoor plants is the original Haus Bright LED Grow Light Bulb. Compared to others in its category, this bulb is notably bright with full-spectrum power. 

Though it's a little more expensive than the GE option, it produces 1,200 lumens of brightness and 140 micromoles per second while only using 20 watts of energy. This LED bulb provides adequate, nourishing lighting for houseplants, bamboo, cactuses, succulents, flowers, tomatoes, vegetables, and seed starts, no matter how cold or dark it is outside.

It arrives fully assembled and can be hung or mounted flush against your ceiling or walls. Designed to mimic natural sunlight and work as a replacement for traditional greenhouse bulbs, this product delivers. 

It emits 450 nm of blue light and 655 nm of red light, the perfect combo for indoor gardening. The blue encourages the growth of tall, leafy plants and vegetables, and the red promotes budding, fruiting, and flowering. Plus, it has a low heat emission, which prevents burnt leaves and reduces your electric costs.

Best Hanging: Soltech Solutions Grow Light

Best for Herbs: TorchStar Plant LED Kit Indoor Herb Grow Light

The best option for herbs is also from TorchStar. With full-spectrum solar simulation, the LED Plant Kit provides both the right lighting and a container for growing herbs indoors. Mimicking natural sunlight, it illuminates for 16 hours a day and then turns off for 8 hours at night. 

This herb grow light measures 19.9 x 2.2 x 14 inches. It's the perfect size to place on your windowsill, desk, kitchen counter, mantle, dresser, or side table.

Best Adjustable Spectrum: iPower 10W Dual Head LED Grow Light

ipower-grow-light

The iPower LED Grow Light has two flexible gooseneck arms and two light heads. But the rotatable necks aren't the only thing that's adjustable on this lamp. It has three light modes (red, blue, and a red/blue combo) and 11 dimmable settings. The smart timer allows you to set it to turn off after a certain amount of hours, and then turn on at the same time the next day for a 24-hour cycle.

Like the CFGROW lamp, this grow light has a large mounting clip, which you can attach to a desk, table, shelf, or any other slim ledge. It comes with a USB cable and plugs into standard outlets.
