Grand Master LEDs Tarantula Tent Ultimate 5x5 V2

Q: How many watts do I need for my grow space?

The wattage depends on the size of your grow tent or room. A general guideline is 30-50 watts per square foot for high-light plants like cannabis. For example, a 2x2 ft area may need 100-200W, while a 4x4 ft area may require 400-600W for optimal coverage.

Q: What is the difference between full-spectrum and red/blue LED grow lights?

Full-spectrum LED lights mimic natural sunlight, providing a balanced mix of blue (for vegetative growth) and red (for flowering and fruiting) light. Red/blue LED lights focus on specific wavelengths but may not support plants as effectively as full-spectrum lights.

Built for real 5x5 tents this LED grow light delivers uniform coverage higher efficiency and reliable performance growers trust run after run.

Delivers true 5 by 5 coverage with commercial-grade output built for growers who demand consistency

The LED grow light that finally solves uneven canopy coverage in a 5-by-5 tent. The Tarantula Tent Ultimate 5x5 V2 was built for serious indoor growers running soil or hydro who want dense, even bud development wall to wall. With a full-spectrum grow light LED design, 2820 PPF output, and tight diode spacing, this LED indoor plant grow light eliminates hot spots and weak corners. Dial it in with knob dimming or integrate it into a controller driven room for repeatable results cycle after cycle.

Energy-efficient performance is where this grow light's full-spectrum LED separates itself. At 2.82 µmol per joule, this LED grow light for plants delivers far more usable light per watt than HPS systems, which are stuck around 1.3 to 2.1 µmol per joule. That means lower power costs, lower heat load, and more photons available to buds where they are actually used.

Boost Efficiency by Mounting the Driver Outside the Tent

Improve cooling and reduce clutter by placing the driver remotely using the Grand Master LEDs Driver Box Extension. Use one Driver Box Extension per driver (two for dual-driver units like the Tarantula Tent Ultimate 5x5 V2) to streamline your setup.
