The smartest way to ensure your plants get all the (artificial) sunlight they need. Hydroponic Grow
Little natural light in your home doesn't have to mean living without plants — if you invest in an LED grow light. They're designed to mimic the sunshine plants need for photosynthesis, a process that gives them the energy they need to grow and bloom. LED grow lights produce a full spectrum of light, and they’re also long-lasting, energy-efficient, and cool to the touch.
Plus, they come in a range of styles, from multiple bulbs on a strand just like outdoor string lights or Christmas lights to countertop LED grow lights for potted herbs. There are also LED grow light strips that you can mount underneath a shelf and panels that are several feet wide and offer coverage for large-scale growing operations.
While the LED grow lights are often more expensive than other types of grow lights, for many, the benefits are worth the additional cost. Read on for our recommendations on the best LED grow lights for your plants, plus advice to consider before you start shopping.
LED grow lights come in a variety of shapes, sizes, and styles, so you’ll want to consider where you plan to use the light. Just to name a few, there are stick-on LED grow light strips and LED grow lights with a clip to attach to a shelf or desk, as well as classic hanging grow lights for single plants or large indoor gardening setups.
You’ll also want to consider the more technical aspects of grow lights as you shop. Most LED grow lights have full-spectrum bulbs, which give off both cool and warm light to replicate natural sunlight. However, you’ll want to look at each product’s light output, which is indicated by its PPF rating. PPF is the number of photons that a light produces per second, and different PPF levels are better for different types of plants. For instance, low-light plants and seedlings only need a PPF of 100–200, while fruiting vegetables need a much higher PPF of 400–500.
Other factors to consider as you shop include the light’s ability to be dimmed, whether it has a built-in timer, and lifespan.
To find the best grow lights to suit different setups, we looked for top-rated products in a wide range of styles. We evaluated each product based on factors such as its size, installation requirements, energy use, and bulb life, prioritizing options that are easy to use for gardeners of all skill levels. We only selected products with an average customer rating of 4 stars or more, and we read dozens of reviews to get a sense of how each product performs in real-life applications.
