Growing plants and flowers is tricky enough outdoors. Maintaining the right amount of water and nutrients while protecting a garden from the elements is a balancing act. Many people turn to indoor gardens to avoid the challenging growing conditions of the winter or harsh environments. This route, however, brings its own set of challenges.

First and foremost, you are going to need some light. Grow lights provide the same energy to indoor plants that the sun brings to the outdoors. Without them, photosynthesis would be impossible and the plants would die.

Here, the best grow lights to consider for your indoor garden.

Best Overall: Roleadro LED Full Spectrum Grow Light

Cultivate healthy plants year-round with a full spectrum grow light, like our top overall pick—the Roleadro LED 75W Grow Light. Position this grow light above or next to plants at any stage of growth, including seeding, vegetative, or flowering, for a boost of full-spectrum lighting.

This grow light earns high praise for its low heat output, thanks to the aluminum housing that stays relatively cool to the touch. This also means that it’s safe for growing plants to be close to. Some users report excellent results even when plants are within 1 to 2 inches of the LED panel.

Related to the LED panel, customers find the 117 red bulbs and 52 blue bulbs to create balanced lighting that is evenly diffused over the plants. The manufacturer reports that these lights have a PAR of 94 at 24 inches and 205 at 12 inches, making this full spectrum grow light a solid contender when it comes to generating the type of light that plants need for photosynthesis.

While people have used this top overall grow light to grow everything from microgreens and herbs to flowers and fruit-bearing plants, a few people point out that a single panel is better suited to smaller green vegetation only. If you have larger flowering or fruit-bearing plants in your greenhouse or indoor garden, you may need to use more than one panel to support maximum growth and yield.
