Ratings and Reviews
I sought out an app like this after reading “New Plant Parent” and I’ve gotta say it’s really changed my intuitions around lighting. You can use it to see how rapidly the light drops off with distance. I've readjusted all my grow lamps after using it.
Anyway, it's free to try so give it a shot.
