GrowPros Solutions ULTRA400 LED Veg Grow Light - 208-277V | Commercial Use Only

Struggling with leggy, weak plants during the vegetative phase of your grow cycle?

The GrowPros Solutions ULTRA400 LED Low Heat Grow Light delivers specialized illumination specifically engineered for the vegetative stage, promoting compact growth, stronger stems, and robust root development.

Perfect for commercial vertical farmers, propagation specialists, and professional growers focusing on optimizing the critical vegetative growth phase before flowering.

This specialized system generates 1120 μmol/s PPF and 651 μmol/(m²·s) PPFD, providing your plants with the ideal light intensity for vegetative growth while its tailored blue and white spectrum promotes reduced internodal spacing and enhanced root development. With impressive 2.8 μmol/J efficiency, you'll maximize vegetative growth while minimizing electricity costs.

Engineered with vertical cultivation in mind, the ULTRA400's slim profile design integrates seamlessly with multi-tier grow racks, maximizing your growing space efficiency. The IP65 waterproof rating ensures durability and protection in humid growing environments, while the foldable design enables effortless installation without complicated assembly.

Built for commercial applications, this fixture supports 208-277V power outlets for reliable performance in professional growing operations. With diode lifetime exceeding 36,000 hours (L90) and driver longevity of over 50,000 hours, it delivers exceptional long-term value for vegetative growth applications.

Dimmable Control

Adjustable 0-100% dimming allows precision control over light intensity throughout different vegetative growth phases.

GrowPros Solutions ULTRA400 LED Low Heat Grow Light Recommended Setup

For optimal vegetative growth results, mount the ULTRA400 approximately 36 inches above the plant canopy. This mounting height provides the ideal PPFD range of 500-600 μmol/(m²·s) that's perfect for vegetative development while taking advantage of the fixture's low heat emission characteristics.

Important Note: The ULTRA400 is specifically engineered for vegetative growth stages only and is NOT designed for flowering applications. For flowering stages, we recommend transitioning to a full-spectrum lighting solution like the GrowPros Solutions Phoenix or Dragrow series.

GrowPros Solutions ULTRA400 LED Low Heat Grow Light TrolMaster Integration

The ULTRA400 LED Grow Light integrates seamlessly with TrolMaster environmental control systems using the LMA-14 adapter. This compatibility enables connection with the HYDRO-X, AQUA-X, TENT-X, and CARBON-X systems, providing comprehensive control over your vegetative growth environment from a single interface.

The built-in RJ12 daisy chain port allows for simplified connection of multiple fixtures to your control system, streamlining installation and enabling synchronized light scheduling across your entire vegetative growing area.
