Phone Clip Photo Filter for HPS Grow Room Lights
Method Seven made a clip-on mobile phone camera filter to help you take better photos of your HPS-grow-light-lit grow room, and that might be one of the most niche products I've ever heard of.
The Catalyst Phone Clip Photo Filter combines M7 technology with a Carl Zeiss vision lens. Clip it to your smartphone or tablet camera and, according to Method Seven, it will balance the color spectrum to deliver "insane optical clarity when used under HPS (High Pressure Sodium) lights." In other words, it will make your plants look as good as the high they'll one day impart.
And for the less, uh, cultivated readers out there, yes. I'm talking about cannabis plants. The marijuana.
