We researched the top-rated grow lights available online, ranging from as simple as adding a lightbulb, to a full indoor garden system that does all of the work of taking care of your plants for you. We then set up and tested several of these options in our own homes and at the lab for several weeks and up to three months in some cases. We then evaluated their size, wattage, bulb type, ease of setup, and overall effectiveness. Here are the best grow lights for your plants, backed by our thorough research and testing.

We love how versatile this grow light is: Thanks to a wide-opening clamp, you can attach it to almost any table, chair, desk, or countertop. It even has rubber pads on the clamp to prevent surface damage. Plus, the flexible gooseneck allows you to easily adjust the angle of the light. We found it to be extremely portable, easy to set up, and small enough to tuck away in a drawer. We think its compact size makes it ideal for households with a few small plants. You can even screw it into the wall for a more permanent yet space-saving solution, but keep in mind that you will lose the portability.

Designed to be mounted flush or hung against a ceiling or wall, the Feit Electric Dual Grow Tube Light is meant to replace traditional greenhouse lighting and delivers a full spectrum to help achieve optimal results for a variety of plants and flowers. The energy-efficient LED bulbs have low heat emission, so you don’t have to worry about burning your plants&#; leaves. The bulbs emit nm of blue light and nm of red light, an ideal combination that encourages plant growth and photosynthesis.

We loved that each of the plant pods has a note indicating the plant&#;s eventual height (short, medium, or tall) which we found particularly helpful when figuring out where to plant them (front for smaller plants, back for the taller ones). For example, the dill pod indicated that it would grow tall and we found that it grew surprisingly tall (in fact, it grew faster. and taller than any of the other pods). We had to adjust the arm of the light panel higher because the dill started to burn. Luckily the light is easy to adjust so you can make it taller as the plants grow (as high as inches). Also, note that we received pods (it has room for nine), and swapped out two of the extra pods that we initially planted that seemed slower to grow.

This depends on the type of plant, size of plant, and how many plants you are trying to grow.  A single light might be appropriate for a small pot with a single plant or a small seedling tray.  As plants get larger or the required coverage area expands, more lights may be needed.  Generally, if plants are growing well and have a compact, robust structure, they are getting enough light.  If plants are weak, with elongated stems and many small leaves, this may indicate additional light needs to be provided.  Up to eight LED Grow Light fixtures may be connected in series by using the integrated cords and receptacles in the fixtures.  Our LED Grow Lights come in several forms, which may be mixed to provide more light.
