For growing plants, light is a must. But what to do when you are growing your plants indoor with zero chance of sunlight? That’s where the LED grow lights come handy as they replicate the effect of sunlight producing light and heat. Again the question arises, which LED light to choose among so many different models?


Every model brings something extra to the table and has specific features for a particular use. Some models offer maximum coverage, some offer high PAR value, etc. For instance, ViparSpectra UL Certified 450W high end LED Grow Light is a viable option for its reasonable price and effective features.

So consider your requirements and preference first, then choose which is the best LED light for 2×2 grow tent.

How Many Watts for A 2×2 Grow Tent?

If you are thinking about what size light for 2×2 grow tent, it actually depends on the 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

Grow Space SizeGrow Light SizeActual Wattage Required (Minimum)
1 sq ft (1x1)32 watts~30 to 45 watts
2 sq ft (2x1)60 watts~60 to 120 watts
4 sq ft (2x2)128 watts~120 to 140 watts
8 sq ft (2x4)256 watts~240 to 300 watts
9 sq ft (3x3)288 watts~250 to 30 watts
16 sq ft (4x4)512 watts~500 to 650 watts
25 sq ft (5x5)800 watts~700 to 900 watts
32 sq ft (4x8)1024 watts~900 to 1100 watts
36 sq ft (6x6)1152 watts~1000 to 1200 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.
