Before we jump into that, let me first discuss the considerations you need to factor in when choosing your LED grow light.

How to Choose the Right LED Grow Lights?

I used to think that if I got a premium LED grow light, all my questions would be answered. But no, that’s actually not how it works. There is much more than just purchasing an expensive grow light.

Unlike a symmetrical grow space, a 4×2 or 2×4 grow tent is not, and therefore, you really need to think about the specific type of grow light you’ll be using.

So, here are the top considerations in choosing the grow lights you need for your growing cannabis plants!

Consider the Type of Grow Space You’re Establishing

The first factor you need to consider would be the type of grow room you’re trying to put up. As we all know, there are different stages in the life cycle of a cannabis plant, and not all of them fit perfectly suitable with one another in terms of light requirements.

Do you want the plant growth here to be limited up to the seedling stage? Or do you want this space to stretch from seedling up to the vegetative stage — or even the flowering stage?

Your answer will depend on the type of LED grow light you’ll need. If this space accommodates your plant’s entire life cycle, then you need a full-spectrum variable where you can adjust the light intensity between each stage of your plant’s growth.

For instance, the amount of light you need during the vegetation phase is just half as much as you need for the blooming stage. We’ll get more to that later.

Other than the fact that you need to control humidity, temperature, and the amount of heat that is in the space, you also need the right light for your greens, too!

Decide the Amount of Cannabis Plants You’ll Grow

The next step would be to decide how many cannabis plants you want to grow. This actually calls for you to identify the size of your grow tent. For this, you’ll have to answer, how many cannabis plants fit in my 4×4 grow tent? About 8 to 12 plants will fit in a 4×4 grow tent.

By knowing this information, you’ll be able to determine the needed light spread as well as the par output that’s enough for your plants.

Calculate the Needed Wattage For Your Grow Space

Another consideration would be the wattage. How many watts would you need for a 4×2 or a 2×4 grow tent? Well, theoretically, experts suggest aiming for 30 to 50 watts per square foot in your grow space.

To be more specific, the recommendation for higher and better canopy penetration would be 25 watts for vegetation and about 45 to 50 watts for the flowering stage.

So, if you have a 2×4 grow tent, you’d need about 150 watts (vegetative phase) and 300 watts for flowering.

NOTE: Most growers measure it using square feet instead of square meters because it’s easier, and it’s a lot more concrete regarding the amount of light needed.

Identify the PPFD of LED Grow Lights

Lastly would be the PPFD or the Photosynthetic Photon Flux Density of the grow lights you’re considering.

For you to understand it easier, the PPFD indicates how much photosynthetically active radiation (PAR) reached the plant canopy from where it’s hung or located.

Understanding light science is one thing, but knowing the conditions and the environment you want to set up is another.

In growing cannabis plants, knowledge is power, and it will be the key for you to identify the perfect light for your indoor plants.

Many beginner growers are usually still left with waves of questions about choosing the best LED grow lights for their 2×4 grow tent. So, here are some of their frequently asked questions!

What Size of LED Grow Light Should I Use For a 2×4 Grow Tent?

For this, you might mean the wattage of your LED grow light, not the size. The size could be any size; so long as they’re able to provide the correct wattage, they can be used. 2×4 grow tents would benefit the most from grow lights that have anywhere between 200 and 300 watts. It can go as high as 400 watts so that it can also be used up until the vegetation phase.

What Should the Light Intensity Be Of My Grow Light?

This will depend on the type of growing environment you’re planning to put up. Moreover, grow light science defines light intensity as a complex factor, as it includes PPFD, coverage, and PAR. Generally, though, you want the light intensity to match the type of growth you want for the space you have prepared.

What LED Lights Do Professional Growers Use?

In terms of brands, professional growers use a wide variety. However, Horticulture Group (HLG) and Spider Farmer SF series are among the brands most professionals patronize simply because of how
