What You Should Look for in the LED Light for 4 x 4 Grow Tent?

Well-calculated LED lighting brings the perfect balance of light to supplement and control the plant’s photosynthesis.

What Are You Growing?

The very first thing you have to consider is the type of plant you’re planning to grow. This is so since LED grow lights are engineered with respect to the type of growth.

If you are a hobbyist, you can settle for simple and inexpensive designs. However, commercial growers need LED lights with UL or ETL certification.

How much light does your plant require? Usually, the lighter your plant gets the better. Nevertheless, there is a point when your plant may not need additional light.

Extra light creates a condition referred to as light saturation point. If you subject your plant to excess light (beyond its saturation point), it may end up growing poorly.

The lighting requirements for flowering and vegging are not the same. Vegging requires less wattage and light intensity compared to flowering.

Watts per Square Feet

Normally, conventional LED grows lights draw approximately thirty-two watts to light a flowering area of one square foot.

When compared to HID, LED grow lights are energy efficient. However, the LED lights in the market do not have the same energy efficiency.

Usually, the LED light for 4 x 4 grow tent will utilize fewer watts to generate an equal amount of light that a conventional model would radiate.

Low light plants, including lettuces and herbs, need approximately eleven to eighteen watts for each square foot of grow tent space.

You can scale up the wattage with respect to your grow space. Just remember that one square foot of grow tent space needs roughly thirty-two watts of real wattage.

According to research, a 4 x 4 requires around 512 watts, but the wattage can range from 500 to 650 watts.

Light Spectrum

Mostly, LEDs generate light within a narrow spectral range. LEDs are available with peaks at different wavelengths, providing much flexibility in which spectra can be produced.

White light can be generated either by combining LEDs with different wavelengths or by coating blue LEDs with a phosphor.

The specific wavelengths needed for photosynthesis are employed in the engineering of these lights for both the initial and second phases of plant growth.

Research reveals that plants benefit from the exploit of red, green, and blue parts of the perceptible light spectrum.

Which color spectrum is ideal for my plants? There are around fourteen wavelengths. Most high-end models are built with infrared, UV, white, violet, blue, and red LEDs.

These wavelengths are engineered to work exceptionally well in flowering as well as vegetative plant growth cycles.


Photosynthesis, the process by which green plants turn sunlight into carbohydrates, does not use green light.

Plants appear green because they reflect green light. But they have no use for such wavelengths. Green leaves absorb a great deal of the light at blue and red wavelengths.

PAR has a spectral band that ranges between 400 (purple) and 700 (red) nanometers that a majority of leafing plants find necessary for photosynthesis.

The unit of measure for PAR is derived from the number of light particles, or micromoles per square meter per second that strike a surface.

Light Intensity

You may be curious about the intensity of light to provide your plants every day. The different growth stages of your plant depend on how much light they obtain every day.

Light intensity can be a benefit and a disadvantage at the same time. Normally, there is a given amount of lumens that will promote healthy plant growth by sparking the process of photosynthesis.

How many lumens are enough? Well, it depends on what you are growing among other things. The size of the grow tent is the very first thing that you should take into consideration.

The most ideal light intensity (lumens) you need should probably range from 300 to 800 lumens for every square foot.

LED Grow Light Options for 4 x 4 Grow Tent

There are several configurations to choose from, including grow light panels, UFO grows lights and single spot lamps.

Among all the available options, you have to consider color balance. With most lights, the ratio may vary from 4:1 to 8:1. In terms of colors, the ratio is red to blue.

When checking the color ratio (red to blue), ensure the manufacturer has specified the wavelengths, such as 660 nm for the red color, and 460 nm for the blue color.

You will also come across bi-band and tri-band LED lights. The bi-band designs may be insufficient; so, consider choosing tri-bands.

Generally, choose LED to grow lights with more than 90 watts; preferably, 120 plus watts. But most importantly, settle for an option that is suitable for your plants.

Final Words

The benefits of LED grow lights for your 4 x 4 grow tent are irrefutable. These lights produce much more illumination per watt compared to HID lighting or fluorescent help you nurture your plants and their cannabinoids and terpenes. This also means that they run cooler, reducing the need for fans and the risk of fire in your grow tent.

Always remember that light intensity (not brightness) along with accurate spectral calibration are very important considerations. One without the other won’t help your plants.
