Grow Room Glasses

Cerulean Blue is the lens to buy. A Carl Zeiss Growlight lens engineered specifically for grow rooms, in a full-coverage hemp bioplastic wraparound. In stock and shipping now on the EpicGrow.

It cuts the yellow and orange wash of high pressure sodium and hands you back accurate color — which matters, because nearly every early plant problem announces itself as a color change before it becomes anything else. At VLT 35.88%, filter category 2, it also takes the raw intensity down for long sessions under LED, metal halide, CMH and LEC.

Every lens carries the Flash ML infrared coating, absorbing across 780–2000 nm — strong absorption of near infrared, partial absorption of far infrared.

Zeiss publishes transmittance data for these lenses — and if a seller will not show you a curve, nobody measured it.

Tawny Brown, the high-contrast inspection lens, and the RazorGrow frame are custom order only, minimum 1,000 pairs. That minimum is set by the lens, not by us.
