Buyer’s Guide

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

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 growing area such as an indoor garden or a plant wall.

Wattage

A grow light’s wattage determines how much light it produces. 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.

  • 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.
  • Brightness: In addition to color adjustability, LED growers usually have knobs for adjusting the brightness of their light bulbs to ensure optimal light intensity.
  • 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.

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.


Frequently Asked Questions

What is the semiconductor chip on my LED grow light?

The semiconductor chip is the piece that converts electricity into light. The chip itself will have a wattage rating, with at least three watts being enough for adequate light production.

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

Yes. Some freestanding grow lamps sit on or clip to tables. They’re easier to install than hanging grow lights, but they can’t light as many plants.

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.
