Try Trimming under a Blacklight. It’s actually very helpful, all of the sugar and shade leaves glow and the buds do not. The stems stick out with a different glow too so it helps pinpoint where to snip.
Strange… but helpful!

This is interesting but would drive my eyes crazy.

Neat idea!
This is also interesting in the context of that guy a while back who was using a black light to look for PM (or something?) I don’t remember specifics or I would link the thread.
I’m wondering if he was killing plants that were fine or if you are trimming plants that aren’t. 
I think we need more experimentation about what on weed plants glows under black light and what doesn’t!

Great idea!
That’s one of those “why didn’t I think of that” moments…
I’ve only been using my black light to scan for botrytis in later flower. Scanning while trimming (especially outdoors grown plants) makes great sense.

ouuuu, I have one lying around from my zoomer days. Battling PM (powdery mildew) the last 2 attempts.
Now I can use this to check my cleanup to see if I missed any spots or areas

Did you spray Sulphur?
I use my backlight to check for PM but I like this as an alternative option ta!

Nope, but definitely spraying next run 
No, the leaves and stems just “glow” differently.

Spray now and make sure everything is dead. It works better than bleach. Then spray again early veg. Get yourself a hypochlorous acid generator. It sounds fancy, but its just a little thing you dip into a gallon of water with 4 tbsp of plain salt. Plug it into a phone charging block and leave it in for a few hours. It makes organic bleach that wont burn your plants when diluted 1 part hypochlorous acid to 10 parts water. It kills mold and mildew on contact. Safe to use up to day of harvest. I put some in my humidifier in my drying tent.
The generator costs $14 on amazon.
I also used it to replace rubbing alcohol and killed mites with it. I just added 1 tsp each of castile soap with peppermint oil, and castile soap with tea tree oil
I battled pm for way too long. Havent seen it since

Its @JoeCrowe he would have something to say on this he uses UV lights and microscopes .Bird shit will glow like that too if it was outdoor stuff. i identified a bird nest that was made from PM infested Leaves that was covered in Wooley spore masses and bird shit.It lit up like a Christmas tree.Birds kept eating the Japanese beetles off the plants and were like little Feather dusters for spreading PM

I did a search and I see that he’s said that PM glows and the plant itself doesn’t. I was thinking of someone specific and can’t find it now. They were trying to battle it and using a blacklight but then realized something later about whether it was accurately diagnosing or not? I might be conflating things I’ve read. ¯\_(ツ)_/¯

I think there are false positives because PM isn’t the only thing that glows under a black light.

The black light basically makes things containing phosphorous, glow. The most interesting thing I’ve found, is the cap on the trichome containing THC glows. Does the THC crystal itself glow? I broke the flash light. damned thing! I need to make it better.
So if you are looking at your plant with the UV, normally a leaf is king of dull red. If there is mildew it glows. The mycelium network glows.
visible light
Same thing except ultra violet.

If there was something to this all the professional cultivating “places” (CannCribs) that take you around their stages of - have never seen a black light trim room with 25 trimmers (were is the acid) but it just might work !!!
