5 Best LED Grow Lights for 4x4ft Grow Tent 2021

in ledgrowlight •  3 years ago 


A good quality LEDs grow light is a must investment for a 4×4 grow tent. You have made a great effort to grow plants indoor with an efficient control system through a grow tent. But to yield higher from their indoor garden, you need to have proper light setup for your plants. Every grower knows the importance of light in the growing cycle of plants (veg, bloom, flowering). So, choosing the best grow light setup for your grow tent is very crucial. Here we will review the grow lights that have enough lumen/PAR to cover your 4×4 tent. The 4×4 tent is a great size as it’s not too big or small. The lights that can be used in a tent this size vary dramatically. You can use almost any fixture from traditional single-ended fixtures, LED lighting, or Ceramic Metal Halide. The only fixtures that might be avoided are double ended fixtures but that has more to do with height restrictions. Since LED lights are usually preferred for grow tents, we will only discuss best LED grow lights in the market for your tent. For a 4×4 tent, you should have a grow light having an actual wattage range of 400-600 watts (assuming flowering plants which require a lot of light and are congregated in a single area. Vegetative growth for high-light plants need about half this wattage).

In this article, I will reveal my picks for the Best LED Grow Lights in 2021. This list will include LED grow lights that have a flowering coverage area of 4’x4’ and are best for a full-cycle grow (from seedling through flowering). These are complete fixtures only. This list does not include DIY grow lights or lights that require significant assembly. The grow lights are listed in no specific order. For a LED grow light to make this list, I factor in: PAR output, efficiency, spectrum, light spread, diodes, drivers, and warranty.

How Many LED Watts Are Required Per Square Foot of Grow Space?

It could sometimes depend on the plant you’re growing in that space. But as a simple rule, you need to provide 30 to 40 watts per square foot of grow space.

What Features To Look For In LED Grow Lights?

Low Heat Output: Some cheap LED grow light tends to get overheat and make the environment hot. This could burn plants out. Also, LED grow lights that tend to overheat seem to have a shorter lifespan than the ones that don’t produce excessive heat.

Thus you save some money not having to buy LEDs again and installing them.

LED Grow Light With Cooler: Few LED lights have high-quality cooling fans included in them which internally cools the LEDs. This is great for lengthening the lifespan of the LEDs. Thus, you should look for LED grow lights with a high-quality internal cooling fan.

Quality of the Semiconductor Chip: It is like the heart of a LED grow light, and the heart needs to be of great quality, right? This chip is responsible for converting electricity into light and also determines the wavelength of light.

Make sure you buy a LED grow light with a good quality semiconductor chip that has a minimum wattage of 3.
