The Horti‑Vision 315W 10000K CMH (Quartz Metal Halide) Finishing Lamp is uniquely designed for the final two to three weeks of flowering. With its intense 10K spectrum, this lamp delivers elevated UV-A and UV-B radiation to dramatically enhance essential oil, resin, terpene, and flavonoid production, improving aroma, flavour, and overall crop quality. Constructed with double‑jacketed quartz glass and a precision ceramic arc tube, it withstands high-intensity use while maintaining spectral consistency.
Optimised as either a standalone finishing light or a supplemental boost to existing setups, this lamp is ideal for growers focusing on connoisseur-level results. Its targeted UV penetration ensures compact internodes, enhanced trichome formation, and exceptional harvest potency. While powerful, it is recommended solely for the final flowering phase to avoid plant stress.
