🛠️ How to Use It

1. Install under canopy using the included mounting kit - perfect for racks or tents.

🌟 Grow Guys Tips

• Don’t just blast the tops - spread the love underneath. Volcano Underlights bulk up popcorn buds into proper keepers.

• Running a 5×5? Place one bar down each side for even coverage.

• Combine with a spectrum-heavy top light for canopy-to-floor density.

• Remember airflow - with denser lower buds, you’ll need to keep things moving to avoid humidity pockets.

🧃 Perfect For

• Commercial rack growers wanting consistent lower canopy yield.

• Tent growers tired of fluffy bottom buds.

• Anyone chasing full canopy utilisation in 4×4 or 5×5 setups.

• Growers who want to push every last gram from their space.
