Method Seven makes optical lenses, not tinted sunglasses. The point is colour correction: under HPS or LED, everything looks orange or magenta and you genuinely cannot see whether a leaf is pale, yellowing or spotted. These lenses restore something close to daylight colour so you can diagnose plants properly - and they cut the eye strain that comes with a long session under a 1000W lamp.
- LED lenses: Citadel FX and Citadel FX2 in gun metal grey, plus the FX2 (formerly LEDfx Agent 939) - built for the magenta cast of full-spectrum LED.
- LED+ range: LED+ Operator and LED+ Cultivator frames.
- HPS lenses: HPS+ Operator, Evolution HPS+ and the Cultivator LEDfx - see all grow room tools.
- Photography: The Catalyst phone and tablet clip, which corrects colour for photos taken under grow lights.
Why choose Method Seven?
You cannot spot a problem you cannot see. Early deficiency and pest damage show up as subtle colour shifts, and grow light spectra hide exactly those shifts. Correcting the colour is the difference between catching something in week one and finding it in week three.
Method Seven FAQs
Do I need different lenses for HPS and LED?
Yes - they correct for very different spectra. An HPS+ lens under LED will not give you accurate colour.
Are they just for comfort?
Comfort is part of it, but the real value is diagnostic. Most growers notice problems earlier once they start using them.
