The 7 Best LED Grow Lights for Seedlings
Updated on Nov. 21, 2024
If you’re new to starting seeds indoors we’ve rounded up the best LED grow lights for seedlings and helpful tips to get you started. When starting seeds indoors, supplemental lighting is essential.
Plants need light and nutrients to grow. But growing plants indoors can be challenging without the help of the sun. You might be able to get plants to grow on a windowsill, but will they thrive?
“Whether a first-timer or experienced gardener, grow lamps and grow light kits can help cultivate healthy plants year-round,” says Carrie Spoonemore, co-creator of Park Seed’s From Seed to Spoon app. “Many of us aren’t lucky enough to have ample indoor light for plants other than low-light houseplants. If you want to grow more interesting tropical plants, or any edible plants, you’ll need to provide them with the proper spectrum of light they need to photosynthesize, grow and bloom.”
Growing vegetables from seed saves money and you can choose your favorite varieties to grow. Whether you want to start an outdoor veggie garden, grow flowers from seed or boost your droopy houseplants, a grow light can help your brown thumb turn green.
Know that not any LED light will work, though. “Plants require specific wavelengths of light, particularly in the red and blue spectrums, to undergo photosynthesis effectively. While some standard LED bulbs emit a broad spectrum of light, specialized grow lights are designed to provide the optimal wavelengths for plant growth,” says Spoonemore. Look for LED lights labeled “full spectrum” or for ones that are specifically designed for plant growth.
In this article, we’ll focus on getting your garden growing with LED grow lights to start your plants from seed. LED lights are becoming more popular because they are eco-friendly, use less energy, have a longer life and stay cooler than traditional grow bulbs.

Hytekgro LED Grow Light
The two-pack Hytekgro full spectrum LED lights hang easily from a stand or grow tent. Having two lights in your seed starting setup helps you adjust the height individually as your plants grow. These lights hang from steel cables, and each light has 45 watts, brighter than a traditional 40-watt bulb. Additionally, there are an impressive 220 light-emitting diodes providing a generous three-foot spread of light.

The AeroGarden Harvest Seed Starter Tray is a convenient all-in-one hydroponic system with automatic lights to ensure a successful growing experience.

AeroGarden offers a clever 23-pod seed starter tray that fits inside the AeroGarden Harvest to accommodate the seeds of your choice. Warning; things grow fast in an AeroGarden.
