Influence of Music on Plants

Discussion in 'Advanced Marijuana Cultivation' started by jberry, Jan 19, 2010.

    Do plants listen to music? How can a plant possibly respond to music? Well, plants breathe through their many mouths, which are also known as stomata. And it has been discovered that plant stomata respond to music!

    Music and Plants?

    A few years ago, scientists at the University of California, San Diego in the United States discovered a signal mechanism that controls a plant's stomata. The two cells that form the stoma consist of specialized cells (guard cells) that are tuned to the resonant frequency of calcium. When exposed to this frequency the stomata close. However, if the frequency is not exactly right the cells will open again within an hour. This happens even if the concentration of calcium is so high that the stomata would normally close. Experiments showed that exposure to high tones was more or less directly responsible for increased gas exchange, and not just after an hour.

    Music increases growth

    When specific music, high tones or bird song cause the plant to vibrate, but not at the exact frequency for calcium resonance, the stomata will open after a lapse of time, even though the plant would keep them closed under normal circumstances. Tests have shown that a precise leaf fertilizer, tuned to the plant will have more effect on the development and growth of the plant if its stomata are wide open. Which is logical, because plants absorb leaf fertilizer via their stomata. Combinations of frequency and leaf fertilizer are available for many different crops.

    But there are still some catches to this method. If the stomata are forced to remain open the plant will not be able to control the amount of water lost via transpiration and so it risks dehydration. So exposing your plant to music for more than 3 hours a day could endanger its health.

    Don’t overdose on music

    There could also be negative effect on your favourite plants if the volume or frequency are too high. But this cannot yet be explained based on the opening and closing of the stomata. The negative influence of a too high a frequency could possibly be explained using a technique known shell resonance.

    Shell resonance


    Besides resonance, which causes stomata to open under the influence of music or specific tones, there is another technique that might be able to explain the effects of music on our plants. This technique is known as shell resonance and it stimulates or inhibits the synthesis of proteins in plants. Various tones have a role to play here. The theory behind this that proteins, which consist of amino acids, are synthesized in tune to the vibration. Each amino acid should have its own frequency and therefore, each protein its own range of frequencies. So theoretically, the correct sequence of tones should stimulate the creation of proteins by resonance.

    The influence of resonance in the human body is also the subject of research. Transcutaneous ElectroNeural Stimulation or TENS is a technique that utilises a specific frequency to stimulate the generation of specific substances in the body. For example, a frequency of 10 Hz is thought to stimulate the creation of the neurotransmitter serotonin (the same frequency as α-waves). And guess what? Serotonin is an amino acid.

    The reason that different tones could be such an influence on plants is because of hormones, such as auxin which is one of the substances responsible for cell extension and fruit formation, only consist of two amino acids. Allowing the plant to vibrate just long enough at the frequencies of these two amino acids should increase the production of the desirable plant hormones thus resulting in bigger shoots.

    Music could also have an influence on seed germination. A publication in the &#8216;journal of alternative and complementary medicine&#8217; describes a experiment in which music resulted in a higher germination percentage (P < 0.002) and in faster germination (P < 0.000002). By the way, it appears that sound did not have any significant effect on germination. So it seems here that multiple frequencies are significant and because germination is all about hormones, it is very probable that shell resonance has a role to play here.

    Plants Prefer Classical Music...

    A possible explanation for plants reacting positively to classical music and not to heavy metal, is that purer tones are used in classical music, while heavy metal is full of guitar effects such as distortion and overdrive which we certainly cannot consider as pure tones!

    Green Ears

    Even though techniques to encourage plant growth have been around since the time immemorial, the art itself is dying and present-day growers only have a fraction of the knowledge of their forefathers.
    Yet, at the moment it is not exactly clear how music influences the development and growth of plants, but more and more is being discovered about resonance
    physics and we are closer than ever to solid scientific proof and theories in this area.
    Maybe, in twenty year's time people will laugh if you say that plants don't have ears!

    I was thinking about this to day and planed to post a question pertaining to this. I had heard about the link between music and plants. Years ago. I looked up a few links about music and plants:


    What I did not find was anything pertaining to this, "When specific music, high tones or bird song cause the plant to vibrate, but not at the exact frequency for calcium resonance, the stomata will open after a lapse of time, even though the plant would keep them closed under normal circumstances. Tests have shown that a precise leaf fertilizer, tuned to the plant will have more effect on the development and growth of the plant if its stomata are wide open. Which is logical, because plants absorb leaf fertilizer via their stomata. Combinations of frequency and leaf fertilizer are available for many different crops." If this is true it would influence when to use music.

    Mythbusters did a show on music and plants, i think they said busted

    RyanTheRhino Well-Known Member

    i think they did not test mj plants. every species is diffrent. ect... dogs can die from a chemical in chocoloate, but humans can eat no problem. both are under the same Same "kingdom"(animal) and "Phylum" (MAMMALS).

    i think mythbusters tested a bunch of bushes.

    ferns are under the "Filicinophyta"Phylum

    and mj is under the flowering group"

    So im not saying it works but pointing out that life is complex and "sh*t happens diffrently"

    I wonder if all the bass affects the respratory system of the plants.. the vibrations my increase flow... think about it have you ever been in front of a huge speaker turned all the way up.... i can feel my heart beat when there is alot of bass

    jberry Well-Known Member

    as far as i know the article i posted is the most recent and up to date article available that is written by a actual Horticulturist and not a journalist or someone selling a related product...

    mythbusters did not know what they were doing and did not perform a very good test imo.

    Anyone ever try "Sonic Bloom" or know much about it? -The guy who invented it has quite the Biography and seems pretty intelligent. He claims he spent 5 years finding the correct frequency to vibrate the Stomata open, and another 15 years perfecting the correct ratio of nutrients to be applied in a foliar spray while the stomata are open... http://www.originalsonicbloom.com/ ... I'm not saying it works because I personally have never tried it, but i found it interesting and would love to hear any feedback anyone may have?

    Thanks for reading everyone, feel free to share any info you have on the subject... there is still a lot to learn about this subject.

    Its jogged my thinking enough that I think I'm going to setup a radio turn it to PBS and set the timer. Can't hurt or can it. Anyway I've got a timer and a radio to spare why not. I will read the article from sonic bloom. I really haven't used foliar feeding at this point and i'm trying to change things slowly. The somata utilizes Carbon dioxide exhaling oxygen. We know this takes place in the day in MJ like most plant (only use carbon dioxide during light). Somata is open during the day exchanging gas for photosynthesis. http://faculty.washington.edu/ktorii/stomata.html So if music causes the somato to open it would be done at night forcing respiration I guess. Any way most of the studies show benefits to the right music played the right way. For now I do that

    Actually now that I looked they said plausable and here were the results

    "Seven small greenhouses were set up on the M5 Industries roof. Four were set up with stereos playing endlessly looping recordings (as having the Mythbusters actually talk to the plants could contaminate the samples with their expelled carbon dioxide): Two of negative speech, two of positive speech (Kari and Scottie each made one positive and one negative soundtrack), a fifth with classical music and a sixth with intense death metal music. A seventh greenhouse, used as a control sample, had no stereo. The greenhouses with the recordings of speech grew better than the control, regardless of whether such talk was kind or angry. The plants in the greenhouse with the recording of classical music grew better, while the plants in the greenhouse with the recording of intense death metal grew best of all."

    here is a interesting article from Bio/Tech News about Sonic Bloom and its founder Dan Carlson....

    Plants have many tiny openings on their leaves called stomata ["Stoma" means "mouth" in Greek – Ed.] The "stoma complex" is made up of two "guard cells" which surround the pore, or stoma. The guard cells have the ability to open and close the stoma. Although the number varies from plant to plant, stoma range between approximately 500-1000 per square inch of leaf surface area. It is through these microscopic stomata that plants exchange gases with their environment. They "inhale" carbon dioxide and "exhale" oxygen and water vapor, for example. As Carlson was to discover, they can also absorb nutrients.

    It wasn’t long before he had come up with an organic foliar feeding solution which enabled him to get significant growth rates in about three out of every hundred different plants he tried. Carlson was on the right track; but the challenge was to find a way in which he could get a higher percentage of plants to "accept" his product. If he could only find a way to get the plants to "breathe" better, a way to stimulate the stomata into action, then he might have a higher rate of success.

    We now need to pick up and follow another thread of the story which ended up providing Carlson with the key he needed to unlock the "secret" of the stomata. Although it really goes way back to antiquity, we’ll pick it up in the 1950’s with the work of T.C. Singh

    Dr. Singh was head of the department of botany at Annamalai University in India. While conducting microscopic observations of live, streaming protoplasm in the cells of an Asian aquatic plant, he was urged by a visiting professor to see if the streaming process might possibly be affected by sound.
    Knowing that plant protoplasm streaming begins to speed up shortly after sunrise, Singh placed an electrically-operated tuning fork six feet away from the plant and broadcast the note for a half hour prior to 6 a.m. What he noticed was that the sound apparently stimulated the protoplasm to stream at speeds which normally would not occur until much later in the day.
    Singh’s next step was to ask a violinist to play while standing near the plants. At a certain pitch, the protoplasm streaming accelerated. One thing led to the next, until Dr. Singh was playing South Indian music to mimosas and found that after two weeks the number of stomata on the plant leaves had increased by 66%! Singh also soon discovered that the music apparently stimulated above average growth and rates of growth in balsam plants. It wasn’t long before he was playing music to all kinds of plants, including petunias, lilies, aster, onions, radishes, and sweet potatoes, to name a few. The music was played one-half hour per day and was scaled at a high pitch, with frequencies between one hundred and six hundred cycles per second.

    Singh’s published conclusion was that he had "proven beyond any shadow of doubt that harmonic sound waves affect the growth, flowering, fruiting, and seed-yields of plants."

    By the mid-1960s, work on the effect of ultrasonic frequencies, had been conducted in Russia, the United States and Canada. It had been discovered that these frequencies noticeably affected the germination and growth of a variety of plant seeds and seedlings, stimulating some species and inhibiting others.

    Familiar with the work of Dr. Singh and others, Mary Measures and Pearl Weinberger, two Canadian researchers at the University of Ottawa, wondered whether, instead of ultrasonic frequencies, the use of audible frequencies might be effective in stimulating the growth of wheat.
    Over a four year course of experimentation, Measures and Weinberger discovered that the plants seemed to respond best to a frequency of 5,000 cycles per second, which somehow caused accelerated growth and almost twice the yields. But, they didn’t know why . . .

    As word of the effect of audible frequencies on plants continued to get out, researchers (some more "scientific" than others) from a number of different countries tried various kinds of experiments. One of the more controversial of these was Dorothy Retallack, who, in the late 1960s, started her series of experiments by playing the single notes B and D to some African Violets. From there, she played selections to her plants from various Classical composers on the one hand, and rock music selections from Led Zeppelin, Vanilla Fudge, and Jimi Hendrix on the other. In a nutshell, and as you may have already guessed, the plants, seemed to "prefer" the Classical music. So much so, that the plants grew toward the sounds of Classical music [Apparently, they "liked" the Bach the best! – Ed.], while growing away from the sounds of the rock music. Needless to say, Retallack’s work caused quite a stir, especially after the story was reported by various newspapers and other publications, culminating in a nationwide broadcast on the CBS News with Walter Cronkite, October 16, 1970.

    One person who had heard about Retallack’s work and who had then recently learned of the Canadians’ research with wheat, was a retired dentist and avid horticulturist by the name of Dr. George Milstein. Milstein decided to see for himself how sounds would affect various kinds of plants. He was serious enough about his work that he sought the assistance of an NBC sound engineer in order to conduct his experiments. The upshot of his work was that when the plants were exposed to a continuous hum at the frequency of 3,000 cycles per second, growth was accelerated, even to the point where some of the plants bloomed as much as six months ahead of what would be a normal schedule.

    Milstein later connected with Pip Records who agreed to let him make a record of the plant stimulating sounds. Rather than merely recording a monotonous long-play 3,000 cycle hum, Pip wanted the record to contain real music. So Milstein embedded his plant stimulating frequency in a recording of a popular musical selection. For best results, he recommended that the record be played daily.

    Up to this point, a number of researchers had concluded that sound frequencies could and did have an effect on the growth and development of plants. However, and although there was no lack of speculation, the reason why sound affected plants remained still unexplained. Which brings us back to Dan Carlson . . .

    Carlson, still wondering how he might find a way to stimulate plant stomata, serendipitously came across a copy of Milstein’s record. This set him thinking in a direction which eventually led to the answer he had been seeking: given the fact that some sound frequencies stimulate positive responses from plants, perhaps there might be a frequency, or frequencies, which would case the stomata to open. He was later to discover a combination of frequencies which in fact did just that. What happened next was quite a surprise . . .

    Stomata-stimulating frequencies now in hand, Carlson collaborated with a Minneapolis music teacher by the name of Michael Holtz in order to produce a cassette tape in which the sounds would be embedded in a recording of popular music. Although he didn’t at first realize or even expect it, Carlson later discovered that his special frequency combination was something which was anything but unique to him. Within just seconds of hearing Carlson’s special sounds, Holtz’s trained ear immediately recognized the pitch to be a kind of sound he had heard many times before: Carlson’s frequencies turned out to be very similar to the frequencies and harmonics of birds as they sing their songs beginning just before the sun rises each day! According to authors Peter Tompkins and Christopher Bird, "Dan Carlson had instinctively hit upon frequencies that were the ideal electronic analog for a bird choir.!

    All of a sudden, it made perfect sense to Holtz. "It was thrilling to make that connection," he said. "God had created the birds for more than just freely flying about and warbling. Their very singing must somehow be intimately linked to the mysteries of seed germination and plant growth."
    At that point, Carlson set about to confirm that his "bird frequencies" did in fact stimulate plant growth. One of his early experiments involved the purchase of a tropical Purple Passion vine, sometimes referred to as a "velvet plant." Taking his potted vine home with him, he began playing his "bird music" to the plant while he dabbed nutrient onto its leaves with a cotton swab. The plant started to respond. As the vine began to grow, Carlson started placing teacup hooks every six inches into his kitchen walls so that it could have needed support. The vine grew so fast that he had to hang hooks an additional three feet of length every week.

    Over the course of three months, Carlson’s pet plant, which would normally be expected to have grown about 24 inches, had in fact grown a total of 150 feet! And it didn’t stop there, either. It continued growing at the same rate, forcing Carlson to drill a hole in the wall between his kitchen and living room in order to give the vine more room to roam. Carlson then strung wires back and forth along the ceiling, which supported the plant as it managed to grow to a length of about 600 feet by the end of the first year!
    The next year, Carlson began selling "starts" to his vine at a local flea market. He cut off small shoots and placed them in plastic pots, which he would sell for $4 each. Four hundred of these young plant starts were sold, along with Carlson’s guarantee that he would replace any shoot that died. Carlson says he received a number of calls from people who bought the plants, but not because they had died, but because the plants were quickly growing to lengths of thirty, forty, fifty feet, and more.

    Carlson ended up contacting the publishers of the Guinness Book of World Records, who sent representatives to Minnesota to verify his claims. After careful measurement and confirmation, Carlson’s 600 foot long pet Purple Passion vine was a World Record holder. The plant didn’t stop there either. It eventually grew to more than twice that length [almost one-quarter of a mile long! – Ed.] and when Carlson called the Guinness folks about the plant’s new achievement, they said they weren’t going to send anyone out that time; there was no reason to do so, since they were confident his original record would not be broken.

    In addition to the rapid and extended growth, the Purple Passion plant bloomed more frequently than normal and some of the new leaves it put out were similar in shape and form to that of one of its "cousins," another vinous plant of the same genus. Evidently, Carlson’s combination of sound and foliar solution also affected the genetic makeup of the plant. So much so, that he later discovered his treatment method had a positive effect on the seeds’ potential, with the successive generation of plants often being 50% larger and more fruitful than their parents!

    Two [Green] Thumbs Up!
    Since those earlier days of experimentation and development, Carlson has had the pleasure of personally witnessing some amazing success stories from home-gardeners and commercial growers whose curiosity was piqued just enough that they decided to give his unorthodox methods a try. Space obviously won’t allow it here, but we could fill a book or two reporting on all the exciting accounts of extraordinary growth rates, hardier, healthier successive generations of plants, incredible produce yields, much-higher nutritional content, and better-tasting fruits and vegetables.

    Both seeds and cuttings from plants will greatly benefit from Sonic Bloom treatments. Seeds can be soaked overnight in the nutrient solution while being "serenaded" by the "bird sounds" tape, for example. From seeds to harvest, applying Sonic Bloom according to directions helps to create stronger, more disease and pest resistant plants of all types and stimulates your plants to bear more and larger, highly-nutritious produce, regardless of the kind of crop you grow.

    it was more likely some other factor, the myth buster guys didnt really take anything into account that they should have imo :leaf::peace:.

    other scientific research show the opposite results. :leaf:

    i cant find anything that would suggest playing the music at night.... i would play the music right when the lights come on for a maximum of 3 hours... if u could mist them with water or the correct nutrient ratio while the music was playing then the stomata would be able to absorb it better since the music is vibrating them open at that time... sonic bloom suggested rain water as a second choice to their sonic bloom nutrient.

    So how does music affect plants? Music, like sunlight and wind, is considered a stimulus, something that incites action in plants. The sound waves created in music also create tiny vibrations. Humans can feel these vibrations by turning up the bass on a stereo.

    According to Penn State&#8217;s Horticulture expert Rich Marini, the vibrations from music and speech might actually stimulate plant growth.

    Wind also creates similar vibrations. When plants are regularly affected by wind, a hormone called ethylene is released. This hormone creates thicker, stronger stems and might be the same hormone released when plants are played music.
    However, too much of this hormone can stunt plant growth, which might be why music played for more than four hours a day can make plants sickly.

    There still has not been a lot of professional research on plants and stimuli, but there have been some new discoveries. In 2007, South Korean researcher Mi-Jeong Jeong studied plant genetics and their reaction to stimuli. He discovered that sounds at certain frequencies (125 Hz and 250 Hz) speed up genetic activity within rice plants.

    Perhaps this study is why many Professional Greenhouses play Classical Music to stimulate plant growth.
