What Size LED Grow Light Do I Need?


What’s the right size LED, and why does it matter?

What size LED grow light do I need? You would be surprised at how many times we get asked this very question. If you’re new to LED grow lights, it’s understandable you have some questions, but it’s vital you don’t underestimate the importance of the right size LED lights.

Having the correct size LED lights for your growing operation, regardless of its size, is vital to the overall quality and yield of your final product, regardless of what you’re growing. You invest a lot of time and money into growing using LED lights, so taking a few minutes to learn the right size LED lights for your grow room or grow tent isn’t much of an investment at all.

In the following article, we’ll be taking an in-depth look at how you can determine the size of LED lights. This includes the size of your plants, how much available room you have in your grow space? And the types of LED grow lights you choose.

How to Decide the Size of your LED Grow Light?

1. The Type of Plants you are Growing

Before you choose your LED lights, consider what it is you’ll be growing, how big it will grow, and how much space it’s going to require on its journey from seedling to flower or fruit. Obviously, the type of plant you are growing plays a considerable part in the size of the LED lights you choose. Smaller plants may require less light, with the lights in closer proximity to the plants and less light coverage.  Larger plants will require more light coverage that covers a more extensive surface area. All high-quality, full-cycle LED lights are capable of growing a plant from a seedling to a flower, including the premium LED grow lights available from Spider Farmer.

2. The Size of your Growing Space

How much space you have will ultimately determine how much light you need. If you’re working with a large area, you have a lot of choices in what you grow, where you place your lights, and how many LED grow lights you use. On the other hand, if you’re restricted by space, then you’ll have to carefully consider how many plants you grow, how big they will grow, and what size of LED grow light you need?

  • A good rule of thumb when growing anything indoors is to have a minimum of 32 watts of LED for every square foot of your growing space.

As an example, if you have a 16-foot growing area, your LED requirement would be approximately 500-550 watts. If you’re growing plants that flower or bloom, they should flourish under these light conditions. However, if you’re growing fruits or vegetables, they will grow using about half the recommended light.

Below is a quick reference guide for calculating how much LED light you need in your grow space:

Grow Space  Wattage

  • 4 Square Feet (2 x 2) 120 Watts
  • 6 Square Feet (2 x 3) 200 Watts
  • 9 Square Feet (3 x 3) 300 Watts
  • 12 Square Feet (3 x 4) 400 Watts
  • 16 Square Feet (4 x 4) 500 Watts
  • 20 Square Feet (4 x 5) 640 Watts
  • 25 Square Feet (5 x 5) 800 Watts

3. The Size of your Grow Tent

If you’re using an indoor grow tent, it will determine the size of your grow lights. When you purchase your grow tent, it will include the exact size details. You can use this sizing in conjunction with the chart in the section above to select how much LED grow light you need.

Most reputable grow tent manufacturers will include recommendations for lighting with their grow tents, including maximum lighting sizes.
