Have you ever been close to one of these devices when hooked up to plants? Iâm wondering what you think of them?
Many years ago, we went to purchase a Fig tree at a nursery on Denman Island, in British Columbia. While we were there, the nursery vendor showed us his plant music devices that he was selling, and hooked them up to different plants, so we could hear the sounds. And, when he hooked several of them up to different plants at once, it seemed as if they were harmonizing, almost like a kind of chorus. The sound, while âdigitalâ, was nevertheless somehow soothing and it fascinated me (being a musician myself). I normally prefer the music of âacousticâ instruments, over âdigitalâ ones â but I found it surprising what a calming effect this had, and my husband and I will never forget this experience that we had at that plant nursery many years ago.
Here is a little blurb written by the distributor about that vendor (who retired from business): https://www.plantmusic.com/emerald-voices-musical-trees-in-canada/
I think that a place in Italy, called Damanhur, may sell some of those devices, as well as Plant Music in the USA (and their web site also shows a network of distributors in Europe).
Thank you for sharing!! 
The real question to me, is the plant âhearingâ the sounds it is âmakingâ and if so, is it altering itâs chemicals now that it is given a feedback system/advice? 
âa little flat here, ok how about nowwwwwwwwwâ
That is a very good questionâŚ
I havenât yet made up my mind about any of this stuff yet â still in the (ever expanding!!!) âquestionâ stage â (and also considering âplaceboâ phenomenae in the ear of the beholder) â (Also thinking about some ideas in David Elkingtonâs book âThe Ancient Language of Sacred Soundâ)
I did find interesting the experience of some kind of effect, on my own ears and psyche, while listening to this device in action for a good hour while we had lunch with the nursery owner. As our host hooked up the plants to individual devices, the devices (which were each also hooked up to speakers) emitted sounds individually, but after a while, the sounds seemed to âsynchronize harmonicallyâ â that is to say, they made sounds that sounded harmonious to my ears, and the ears of everyone at our lunch table, like a kind of ethereal chorus. The phenomenon left unexplained questions and mysteries in my mind.
Plants are constantly respiring and transpiring, and so there are a lot of alchemical reactions taking place in a plant to harness solar (with mineral and vapour inputs) energy that yield byproducts in liquid, solid, and gaseous material states. Undoubtedly, energetic frequencies are involved in the alchemical conversions, and frequences can by harnessed by devices such as those to which we were listening, and converted to audio sounds that we can then perceive with our ears. To what extents can plants respond to frequencies we canât perceive with our ears, as well as those which we can? And, can this be important to our own lives?
Your question becomes ever more interesting when compared with questions that other people have been exploring, about the effects of other kinds of energetic frequencies (e.g., cell phone towers) on plants:
I know for myself: some frequencies drive me nuts, and some I find very soothing and calming, and some energizing. Plants are very mysterious life forces, and I have no reason to doubt that they are also impacted by life-enriching and life-degrading frequencies, in their own unique ways.
