HPS Phone Camera Filter for Accurate Grow-Room Photos
Method Seven’s Catalyst Phone Clip Photo Filter lets you capture natural-looking images under HPS lighting so your plants look the way they do to the eye. The high-quality Carl Zeiss lens balances the color spectrum, removing harsh amber tones for crisp, share-worthy media.
Built for LED (Magenta/Red/Pink) and HPS Lighting
Swap between the HPS lens and an LED lens designed for magenta, red, or pink spectrum fixtures to correct color across different rooms, tents, and light recipes—ideal for documentation, content creation, and remote diagnostics.
Durable, Versatile, and Easy to Mount
The 37 mm aluminum alloy screw mount detaches for use with adapters—even on security cameras—while the aircraft-grade, high-temperature polymer clip keeps the filter secure on phones or tablets during scouting.
How It Helps Growers
By delivering neutral, accurate color, this filter makes it easier to spot nutrient issues, pest pressure, and environmental stress that are masked by intense spectra. It also upgrades your photo/video workflow for training teams, logging progress, and marketing.
