I was wondering if anyone here has experimented using UV lights to detect bacteria or contamination in general in their setups, spawn, substrate etc.

I saw that blotch is florescent and UV at 365nm would make it glow greenish yellow, so I bought a small UV flashlight and I've been testing inspecting the farm with it. So far I've seen the most use when checking out spawn bags, as I can see weird colored glowing stuff in bags that to the eye seem normal... Anyway it's still under the experimental phase but wanted to share and hear your thoughts!
