Wow, that was an interesting read! Listening to the Thirsty tomato plant was trippy!
I thought this was nuts… My interpretation: if you have a dog, they might be able to tell you if the plant is thirsty LOL:
"The plants’ short sounds were about as loud as a typical conversation, but too high-pitched for humans to hear (though dogs’ ears might perk up). And each plant species had a recognizable “voice.” A machine learning algorithm the team created could tell the difference between clicks from tomato plants and tobacco plants. It could also pick out thirsty and hydrated plants.
The algorithm could even differentiate between plants when they sat in a noisy greenhouse, filled with the sounds of people talking and building renovations next door."
