I'm completely convinced that people who pin and share these things on Facebook have never actually tried glow-in-the-dark paint. The first thing wrong about this image is that well, it's not night. At all. The second is the amazing glow the pots are putting off, enough to even illuminate the grass. Glow-in-the-dark paint won't do that.
You see these aren't just painted pots, they are LED-lighted pots. I've been trying to track down the direct source of this image, but haven't been able to. However I have found enough variously similar planters to show you, like these from Konstsmide, a German light manufacture:
And just like in other various "Glow-in-the-Dark" pins, people don't seem to take in account that glow in the dark paint is very green/yellow. In fact there is a great review and write up about two different popular glow-in-the-dark paints at Observation Blog. Here is his 2 examples of the paints, which even with 8 hours of charge were barely glowing, surely nothing strong enough to light up the grass around it.
So once again, put down the paint, people. Sadly this isn't even near what the original image is. And please let me know if anyone knows the source of the original image! I'd love to email the photographer or landscapers who did this and give due credit.
