Our Full-Spectrum Light Buying Guide

Growing your own plants can be very rewarding. Whether you lack the backyard space for a garden and want to grow vegetables in the kitchen, or you love having tons of houseplants around, the proper equipment will help you successfully grow plants indoors. One of the most important tools is a full-spectrum light, as this allows you to provide the plant with its preferred amount of light.

When selecting a full-spectrum light, you’ll need to consider how big your growing area is. There are units that are designed to provide light for approximately one to four plants, as well as models, such as the Maxsisun Sunlike Full Spectrum LED Grow Lights, which cover a 2-foot by 2-foot space.

Look for flexibility when opting for a small full-spectrum light. The Jueyingbaili 80W Full Spectrum Plant Lights comes with four adjustable arms that can be twisted and bent to provide light at just the right angle for up to four plants. The unit is lightweight and portable, which makes it a great choice for both home and office. It’s also powered via a USB or AC power adapter.

Check to see how customizable the full-spectrum light is, as you want to ensure it allows you to provide just the right amount of light. For example, some models have three different light settings, while others come with as many as nine dimming levels. You can even purchase a full-spectrum light with a timer that will automatically turn on and off based on times you enter into the system.

Review the type of light that is used, as you want a full-spectrum light that most resembles the natural light from the sun. Some models imitate sunlight while also being easy on the eyes. Others don’t flicker or produce a glare.

Consider a full-spectrum light that runs quietly. Some models use a fan to stay cool to the touch, and these fans are often noisy. Instead, go with a model that is cooled by a thick 3-millimeter aluminum heat sink. This passive heat exchanger runs without making a sound and works by transferring the heat to a cooling medium before expelling it from the machine.

Finally, you’ll want to choose a full-spectrum light that is energy efficient. Look for lights that use 1,000-watt LED lights and are built with a 90-degree reflector that allows you to concentrate the light. This results in losing 30% less light, which means you’ll use less energy. Some models are so efficient that they use 50% less electricity than other lights on the market, so make sure you do your homework if you want to keep your electric bill low.

Simplemost Fun Fact

There are a great number of plants that grow well indoors. Here are a few you may want to consider — though if you have pets, you should always read up on whether a plant is toxic for cats or dogs. You don’t want to bring something into your home that’s dangerous to your furry friends.

  • Tomatoes: Tomatoes are easy to grow and only need about 6 inches of soil. Depending on the species of tomato, it generally takes between 50 and 100 days until you can harvest the tomatoes.
  • Herbs: Wouldn’t it be nice to reach over and grab some freshly cut herbs as you’re cooking? Quite a few herbs are easy to grow in pots in your kitchen, including basil, chervil, mint and oregano. Their light requirements differ, though, so group them under your full-spectrum light accordingly.
  • Snake Plant: The snake plant is a houseplant that’s well known for its ability to purify the air. The snake plant can grow to a height of 3 feet, however, so you’ll want to make sure you have room for the plant before you buy one.
  • Rubber Tree: Although the rubber tree plant requires a great deal of light — which you can provide via a full-spectrum light — it can handle neglect in other areas. That makes it a great choice for those who don’t have a green thumb.
  • Coffee Plant: If you enjoy a freshly brewed cup of coffee, consider going with a small arabica coffee plant. One plant won’t produce enough beans for your daily cup of coffee, but it might produce a few for the occasional cup, and regardless, it’s a beautiful plant to have in your home.
  • Peace Lily: Peace lilies are not only beautiful to look at when they flower, but they’re also known for removing formaldehyde, benzene and trichloroethylene from the air.

The Full-Spectrum Light Tips and Advice

  • Some full-spectrum lights can get a little too hot to the touch, so use caution when adjusting or moving the lights after they’ve been on for a while.
  • Where you place the full-spectrum light, and for how long, is dependent upon the plant’s stage of growth. Ideally, you want to set the light 8 to 10 inches above a seedling and have it turned on for approximately 12 to 14 hours per day. At the vegetative stage, hang the light 6 to 8 inches above the plant and run the light for 14 to 16 hours each day. Move the light to within 4 to 6 inches of the plant when it reaches the flower and fruit stage. Keep the light on for 14 to 18 hours each day.
  • Look for a full-spectrum light that is splash-proof, as you’ll need to water your plants from time to time and splashes happen.
  • Avoid using full-spectrum lights that have infrared or ultraviolet lights, as these have the potential to hurt your eyes.
  • Make sure the light unit you select is suitable for all stages of growth. You don’t want to have to purchase one light for seedings and another for plants that have reached the fruiting stage.
  • Full-spectrum lights have a wide range of uses. In addition to setting them up for your indoor plants, you can also use them for tissue culture, vegetable cultivation, breeding, growing greenhouse plants, illuminating an aquarium and pipeline cultivation.
  • If price is one of the factors you’re considering when shopping for a full-spectrum light, you’ll find the Jueyingbaili 80W Full Spectrum Plant Lights is the most affordable. The Maxsisun Sunlike Full Spectrum LED Grow Lights, however, is a bit more expensive than most.
