LED Grow Light Buying Guide

Before buying an LED grow light, read our buyer’s guide below to learn about important factors to help you make an informed purchasing decision.

Grow Light Coverage

Grow lights typically give you measurements for how much vegetative and flowering coverage they offer. Be sure to choose a light that matches the amount of light and type of coverage you need for your indoor growing area, grow tent, or plant wall.

Grow Light Wattage

A grow light’s wattage determines how many lumens of light it produces in your grow room. Different plants require different amounts of light, so don’t just choose the light with the highest wattage to ensure optimal plant growth. Instead, match the wattage to the plants you’re growing. For example, if you’re growing tomatoes, choose a grower that offers about 32 watts of light per square foot.

Adjustability

Several features of your LED grow light should be adjustable.

• Brightness: In addition to color adjustability, LED growers usually have knobs for adjusting the brightness of their light bulbs to ensure optimal light intensity.
• Color: Plants need a different color light for every step of their growing cycle. The best grow lights offer red lights, blue lights, and white light color options.
• Proximity: You can also adjust how close the lights are to your plants by lengthening or shortening the rope or chain they’re hanging from.

Grow Light Installation

Grow lights are usually mounted to the ceiling with a chain or rope. This installation process can take anywhere from 30 minutes to a couple of hours.

Other Ways To Help Indoor Plants Grow

LED grow lights are a great way to help indoor, clean-air plants grow, but there are various other ways to help your indoor plants reach their full potential. Here are important steps our team found that you can take to help your houseplants grow and increase their versatility.

Be Aware of Light Conditions

While LED grow lights help, try buying plants that most closely match the light situation in your household. For example, if you have small windows or little natural light, focus more on plants that can thrive with minimal sunlight. Also, you should be aware of how well a particular plant does in terms of distance from the window and sun direction to help ensure it will grow to its maximum potential. 

Water With Caution

Everyone knows plants need water, but overwatering can also become an issue if you’re not careful. To help your plants grow to their peak, check the soil carefully before watering. Put your finger 2 inches into the soil to see the moisture level. If it’s not fully dry, you may want to hold off on watering it. 

Pay Attention to Pests

Pests can be a significant nuisance to plant growth. To help ensure your plants are being infested, check them regularly for bugs such as aphids, gnats, and whiteflies and treat them immediately if you see them. 

Avoid Winter Fertilizing

In the winter, plants become dormant and do not need fertilization. Fertilize only in the spring and summer months to ensure proper growth. 

Be Mindful of the Pot

Choosing the proper plant container for your plants is an important factor when it comes to growth. The first step is making sure your plant pot has holes for drainage. Additionally, you should also purchase a container that’s at least 1 inch larger in diameter than your plant’s root mass. When a plant begins to outgrow its container, it’s crucial to re-plant with a larger container to help it continue to grow properly. 

LED Grow Light FAQ

What is the semiconductor chip on my LED grow light?

The semiconductor chip is the piece that converts electricity into light. The chip will have a wattage rating, and 3 watts is the minimum for adequate light production.

Are there other types of grow lights that don’t hang from the ceiling?

Yes. Some freestanding grow lights sit on or clip to tables. They’re easier to install than hanging grow lights but can’t adequately cover as much area.

Will my LED grow light increase my electricity bill?

LED grow lights are energy-efficient so they won’t increase your monthly electricity bill by much.
