Purpose built to deliver true wall to wall performance in serious 4 by 4 grow tents.

This LED grow light is engineered for growers who are tired of chasing even coverage in a 4 by 4 tent. The Tarantula Tent Ultimate 4x4 V2 delivers a clean full spectrum LED grow light output with tight photon distribution that eliminates hot spots and shadowed corners. With 2098 PPF and a carefully tuned grow light full-spectrum LED design, this LED indoor plant grow light supports strong veg structure and dense flower development in soil or hydro systems.

Is the Tarantula Tent Ultimate 4x4 Energy-Efficient?

Absolutely. Energy-efficient performance sets this grow light LED apart. At 2.76 µmol per joule, this LED grow light for plants produces significantly more usable plant light than HPS systems, averaging 1.3 to 2.1 µmol per joule. That means lower electrical draw, reduced heat load, and better canopy level efficiency without sacrificing output.

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 (two for dual-driver units) to streamline your setup.
