FAQs

What is the main benefit of adding a UVA supplement bar?+

The primary benefit is an increase in harvest quality. UVA light exposure triggers a defense response in plants, leading them to produce more resin, terpenes, and cannabinoids. This results in enhanced aroma, flavor, and potency. You can learn more about how HLG quantum board technology optimizes plant growth.

When should I use the HLG 30 UVA bar in my grow cycle?+

For best results, use the UVA bar during the final 2-3 weeks of the flowering stage. It is typically run for 2-4 hours per day in conjunction with your primary light's cycle to simulate the intense, natural sunlight that plants use as a signal to protect their flowers with resin.

Is this a standalone grow light?+

No, the HLG 30 is a supplemental light only. It is designed to work alongside a primary, full-spectrum light fixture like the HLG Scorpion Diablo or the HLG BlackBird. It does not provide the necessary light spectrum for vegetative or full-cycle growth on its own.

How do I install the UVA bar?+

Installation is flexible. It comes with two hangers for independent suspension at your desired height. It also features a simple bolt-on design for direct attachment to compatible HLG fixtures, including the HLG 550, 600 Rspec, 650R, and Scorpion models.

Can I use this with a non-HLG grow light?+

Absolutely. While it's optimized for easy integration with select Horticulture Lighting Group models, you can use the included hangers to suspend it independently in any grow tent or room, regardless of your primary light's brand.
