HLG 30 UVA Supplement Bar LED Grow Light

Are you looking to push your plants beyond their limits and unlock their full genetic potential? The HLG 30 UVA Supplement Bar is the key to elevating your harvest, specifically designed to add a targeted UVA spectrum that enhances resin production, boosts terpene profiles, and improves overall plant health. This compact, efficient bar integrates seamlessly with your existing setup, providing the crucial light spectrum that primary LED grow lights often lack, resulting in a higher quality and more potent final product.

Engineered for simple bolt-on installation, this 24-inch waterproof bar is compatible with a wide range of premier Horticulture Lighting Group fixtures, including the Scorpion, Diablo, and Rspec series. Its fanless, passive cooling design ensures silent and reliable operation for years. By introducing 365nm and 385nm light, you give your plants the signal to protect themselves by producing more trichomes and flavonoids, translating directly to a more valuable and impressive harvest.

FAQs

What are the main benefits of adding UVA light to my grow?+

Adding UVA light helps stimulate the plant's natural defense mechanisms. This encourages the production of resin, terpenes, and flavonoids, leading to more potent, aromatic, and flavorful yields. It can also help suppress the growth of mold and deter common pests.

How should I use the HLG 30 UVA supplement bar?+

This bar is designed for supplemental use. For best results, run it alongside your primary flowering light, such as an HLG Scorpion Diablo, for 2-4 hours per day during the final weeks of the flowering cycle. This timing maximizes its impact on resin production.

Is this a standalone grow light?+

No, this is a supplemental LED grow light designed to add a specific spectrum to an existing full-spectrum setup. It does not provide all the light wavelengths a plant needs for complete growth and should not be used as a primary light source.

Is the HLG 30 UVA bar difficult to install?+

Not at all. It features a straightforward bolt-on design for direct attachment to many HLG fixtures. The package also includes two hangers, providing flexible mounting options to suit any grow space configuration.

Can I learn more about HLG's technology?+

Absolutely. HLG is a pioneer in high-efficiency quantum board technology, which has set new standards for performance in the industry. You can learn more about their innovative designs in this detailed HLG Quantum Board guide.
