I got my firefly petunias from light.bio around a month or so ago and they’re now just starting to take off. This picture was taken in a dark room with no windows, though I’m sure the phone brightened it up a bit. They aren’t as bright as I was imagining, but I still find them neat.
@Doxatek lol. This picture oversells how bright they are. A guesstimate on my part would be a 10x increase would bring it up to the level of a glow in the dark sticker.
That’s true. Fluorescence is just metabolically expensive.
