Does anyone know why my seedling is glowing?

[Ruka]

Hi everyone!
So I may have accidentally-on-purpose crossed two species that were probably never meant to meet (don’t worry, nothing carnivorous… I think). Everything looked normal until last night when I checked on the tray and one of the seedlings had a faint neon shimmer.
Has anyone else had seedlings do that? Should I be excited or mildly concerned? (I’m choosing excited until proven otherwise.)

A picture would be nice. But beyond that, need more information, like the two species crossed, i.e. botanical names, not the common names.

As I can discover there are no naturally glowing land plants, but genes from glowing fungi have been introduced to some, such as the 'firefly' petunia. I think one of your parents must have been something like this.

Is it glow in the dark glowing, or extra shiny in the light glowing? Buttercups reflect uv rays that you can kinda see and make them shiny

A drop of water has a rainbow spectrum when the light hits it just right. A water drop acts like a tiny prism, bending and refracting sunlight as it enters the drop and reflecting it off the back and bending it again as it exits, which saparates the white sunlight into its different colored wavelenghts.

(red, orange, yellow, green, blue, indigo, violet). Each color bends at a slightly different angle, creating the spectrum of colors we see when light interacts with many droplets in the air, like after rain or in mist.

Fluorescence, when non visible, usually ultra violet, light is absorbed and excites the electrons in the substance so they emit light in the visible range making it look brighter than expected from normal reflected light.
