Buying Guide For The Best 2×4 Grows Light

Can’t figure out what your specific needs are?

Then, I recommend going through some factors that help you find them out. Here are the things you should consider before getting the best-led light for a 2×4 grow tent.

Light Intensity 

The intensity is the first thing you need to think about when buying a light for grow tent. You need to get the proper intensity on the lights based on the growth of your plant and the size of your grow tent.

To choose the perfect intensity, you can look at two things, the PPFD rating, and the PPF rating. Typically, a 1100umol/s rating PPF should be enough for a 4×4 tent. For the PPFD rating, if you are getting lights for plants that are at veg state, then it should be around 300 to 600.

If the plants are at the flowering stage, then you should get 600 to 1000 PPFD.


Next up is the factor of light coverage. This mostly depends on what grow tent you are using. The light you want to get for your tent has to cover up the tent properly. You can find out the coverage area of the light in its description and choose according to that.

Since we are discussing 2×4 grow tents, you can find lights covering such areas. 2×4 is typically a smaller area compared to other sizes of grow tent. So, you should find lights based on that dimension.

But if you fail to find something appropriate, you can also get two lights covering a 2×2 area as it’s much more common than 2×4.


You will also need to consider the wattage draw you get from the lights. While it’s not that important in determining how the light will perform, it can be crucial for efficiency. So, if you are after efficiency, then you will need to consider the wattage draw factor.

Wattage draw determines how much energy the light will be consuming to give you the proper PPF rating you need to grow your plant. Typically, in a 2×4 grow tent, anything around 480w to 600w will get the job done for the most part.

Other than these factors, of course, you will need to count in the price factor here as well. But as it’s much more personal, I won’t be going through that in depth.

The only suggestion I will leave here is to never compromise with the coverage and light intensity because of a limited budget. These two are the most important factors for getting the best results.
