Boost greenhouse yields with Tarantula Greenhouse 320W LED built for efficiency, durability, and full-spectrum control in pro grow setups.

Maximize your greenhouse performance with the Tarantula Greenhouse 320 engineered for high PPFD cultivation and consistent harvest quality.

The Grand Master LEDs Tarantula Greenhouse 320 is purpose-built for commercial greenhouse production, delivering up to 3.5 µmol/J efficiency for powerful, uniform lighting across every square foot. With Samsung and OSRAM diodes, an Inventronics driver, and a waterproof IP66 rating, this fixture thrives in demanding, high-humidity environments. Designed for high-bay installations, it provides deep canopy penetration while maintaining optimal energy efficiency and long-term reliability.

Is the Grand Master Tarantula Greenhouse 320 energy-efficient?

Absolutely. Operating between 3.1–3.5 µmol/J, this fixture outperforms traditional HPS systems (typically 1.7 µmol/J) and even many early-generation LEDs. It delivers more usable photons per watt while consuming only 320W—making it one of the most efficient options for professional growers. With an IP66 waterproof rating and ETL certification, it’s engineered for rugged, continuous operation in high-moisture environments.

FAQs

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.

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.
