Method Seven Citadel HPS

Experience exceptional colour balancing for HPS (high pressure sodium) lighting with our proprietary lenses manufactured for us to exacting standards by Carl Zeiss Vision. The silver plus lens coating makes the Citadel HPS Plus a good choice for outdoors too.

Method Seven technology blends incredible colour balancing for each of the standard grow lighting spectrum's (HPS, Metal Halide, LED, Sun ...) with exceptionally high-quality lenses that provide the best in optical clarity. Additionally, Method Seven protection removes all harmful UV A/B rays like most others but additionally also removes harmful UV C rays which are filtered out of sunlight by the upper atmosphere but are still a significant hazard under grow lighting.

Many growers suffer through unnecessary stress, fatigue, decreased yield, and even permanent eye injury in their grow room experience from using sunglasses or cheaper knock-off grow room glasses. At best, even premium sunglasses attenuate (decrease) excess light in the grow room but do a horrible job of colour balancing in indoor lighting environments, leading not only to discomfort and stress but also to poor viewing and maintenance of your plants.

Treat yourself and your grow to Method Seven quality and style!
