FAQs

What is the ideal hanging height for the HLG 750 Diablo X?+

For the flowering stage, the optimal canopy distance is between 15 and 24 inches. For vegetative growth, a hanging height of 36 inches is recommended to cover a larger 6' x 6' area.

What makes the Diablo Quantum Boards special?+

Diablo Quantum Boards are engineered for maximum efficiency and uniform light distribution. They ensure that every part of your canopy receives consistent light intensity, preventing hotspots and encouraging even growth. This technology is a key reason HLG sets the standard for quantum board grow lights.

Is this light suitable for both veg and flower?+

Yes, absolutely. The HLG 750 Diablo X is a full-spectrum LED grow light, meaning it provides all the necessary light wavelengths for the entire plant lifecycle, from seedling to harvest.

How does this compare to the HLG Scorpion Diablo?+

Both lights use similar high-efficiency Diablo Quantum Boards. The primary difference is the form factor. The HLG Scorpion Diablo features a wider, six-bar design that is ideal for vertical racks and low-clearance grow spaces, while the HLG 750 Diablo X has a more consolidated single-fixture design suitable for grow tents and open rooms.

What is the warranty on this LED grow light?+
