Why do i see green after working on my plants that are under blurple lights ? Is it because there is no green in the spectrum? (growing lettuce under reused growing lights tryin to get away from monsanto food industry)
This reminds me of some of the sciency things we did when I was a kid. For instance, we were told to stare at a picture of a reversed color American or Canadian flag for like 30 seconds without moving our eyes - it was green and black instead of red and white. Then you'd look at a plain white page or something and briefly see a faint reversed image, red and white. Or if you stare at something with a lot of contrast then close your eyes you'll see a ghost image. I have no idea really, but it may be our brains compensating for the lack of green under the grow light, or the rods/cones in our eyes being overloaded by the available spectrum, or something.
Or the blurples are frying your eyes, but I don't think that's it. I know what you're talking about and I know there's a reason, just not what it is exactly.
