How Many Watts for A 2×2 Grow Tent?

The most asked question from beginners, “how many watts for a 2×2 grow tent” ?

If you are thinking about what size light need for 2×2 grow tent, it actually depends on the total size of your grow space. Generally, 1 sq ft of grow space requires about 32w-45w of actual wattage.

For your convenience, here is a quick reference chart to determine the required wattage based on the grow space

Number of Plants  Square Feet Wattage from Wall
1 2 60 to 80 watts
2 4 120 to 140 watts
4 8 240 to 300 watts
6 12 360 to 400 watts
8 16 500 to 560 watts
10 20 600 to 560 watts

The values above are mostly for flowering. For the vegetation stage, you’ll need around half the power (25w). Good quality LED grow lights come with Veg and Bloom switches saving you the trouble of changing the wattage.

What Features to Look for in LED Grow Lights?

Whether you are purchasing grow lights for the first time or replacing the old one, it doesn’t hurt to look for suggestions. These features or characteristics will help you consider one light over another, which one is more suitable for you.

  • If you’re buying full spectrum LEDs, find one with adjustable settings such as VEG and Bloom switch.
  • For high-powered LEDs, always buy the one with proper cooling systems.
  • To ensure proper supply of direct current at all times, find the LED fixtures that have a constant current driver circuit.
  • Consider your grow space while choosing the shape of the lights – smaller lights are good for scattered patterns but panel light offers greater coverage.
