Best LED Grow Light for 6x8ft Grow Room 2021 Update

October 26, 2021

Are you new to the world of LED growing? If so, the charts below will help you determine how much energy (by wattage) your plants require for flowering.

Watts per square foot

The average LED grow light draws about 32 watts to cover 1 sq ft for flowering. Compare this to a typical HID fixture which rings in at 40 watts per square foot (assuming a 5’ x 5’ area, or 25 sq ft coverage area). Using an HID in a 4’ x 4’ will bring the power coverage up to 62.5 watts per sq ft. (The energy saving that growers can expect from using LED grow lights instead of HID is around 38%. This energy savings only takes into account to savings growers gain when using LEDs fixtures. It does not account for other environmental factors where growers can save energy. For example, less ventilation and air conditioning may be used, or foregone completely, depending on the size of the setup and ambient temperatures. Total power savings may rise above 50% in certain scenarios.)

Different LED grow lights will have different efficiencies. More efficient LED grow lights will use fewer watts to emit the same amount of light that a less efficient LED grow light will exude. Therefore, as mentioned above, wattage is not the most accurate tool to know how powerful of a grow light you need for a particular coverage area.

LED Wattage Chart Explanation

The wattages listed below assume you are flowering your plants. If vegging, you might consider reducing your wattage by 50% since vegging plants only require about half the light intensity. As always, it is best practice to follow the manufacturer's recommendations.

In each chart you will find the following columns:
Plants' to be grown
Square footage that the respective number of plants cover
Recommended LED wattage for the number of plants grown in the respective space

Wattage charts

Assume about 32 watts/sq ft (actual LED wattage) for flowering. Fewer watts might equate to smaller yields while more wattage may lead to larger yields.

1' x 1': 32 watts (~30 to 40 watts)

2' x 2': 128 watts (~120 to 140 watts)

2' x 4': 256 watts (~240 to 300 watts)

3' x 3': 288 watts (~250 to 300 watts)

4' x 4': 512 watts (~500 to 650 watts)

5' x 5': 800 watts (~700 to 900 watts)

4' x 8': 1024 watts (~900 to 1100 watts)

6' x 6': 1152 watts (~1000 to 1200 watts)

According to the reference specifications on the above table, we can choose the appropriate LED grow light for our 6x8ft grow tent.

Then I will recommend several popular led grow lights for you.

ECO Farm 320W/480W/650W/1000W/1200W LED Grow Light With Samsung 301B Chips Full Spectrum Commercial Light Easy To Set Up

Description:

ECO Farm LED light strip is a full-cycle spectrum optimized for rapid growth and complete plant development. Tailored for growing plants from propagation to senescence (germination, clones/cuttings, mothers, vegetative and flowering applications) in indoor environments.
ECO Farm upgrades LED is a high-performance, full-cycle top-lighting solution for commercial horticulture cultivation, with the power to scale from vegetative growth to higher light intensities in bloom. It was designed for commercial growers to push the envelope with high-PPFD cultivation practices along with sophisticated CO2 supplementation.
Designed with Samsung 301B chip, higher light intensity, less light decay, better lumens and PAR values than ordinary LEDs. It runs at a lower temperature and can bring higher energy conversion and longer life. This grows light is a full-cycle lighting solution for all growing environments including wet situations and is ideal for greenhouse or indoor lighting.
Flowering period: turn on the light for 12 hours, the humidity is 45-50%.
