Does Music Stimulate Your Cannabis Plants Growth?

Music is a powerful force. It can alter our mood and sway our emotion. It also produces some profound effects in plants, potentially boosting their growth and yields.

Music has a profound effect on the human mind. Certain songs can make you start welling at the eyes, while others can give you that push to hit a new personal record at the gym. But the sound waves generated by music don’t just affect humans.

Music—and sound in general—appears to create profound changes in certain species of plants—from increasing yields to boosting immunity. Does this mean you should start blaring Mozart in your cannabis garden? Or perhaps your herb patch would prefer the soothing tones of Bob Marley?

Continue reading to see if (and how) music can increase the productivity and health of your cannabis plants.


You’ve probably noticed that your cannabis plants don’t have ears. However, this easy observation doesn’t rule out the fact that sound can still influence them on a biological level. Humans are able to detect sound thanks to specialised cells—mechanoreceptors—in the ear.

Put simply, sound is the vibration of molecules through a certain medium, be that solid, liquid, or gas. These vibrations travel through a medium by compressing molecules in the air. When these waves hit the human ear, mechanoreceptors respond to the change in pressure and send signals to the brain.

How plants “hear” music and sound remains unknown. However, a likely theory suggests that plant mechanoreceptors sense the change in pressure as sound waves bash into them and rush past them.


This ability to detect sound allows plants to experience the outside world and act accordingly when trouble arrives. Far from inert green masses that blow in the wind, plants are incredibly aware of their surroundings.

The sound of a caterpillar munching on a plant’s leaves will cause specimens to ramp up production of defensive chemicals designed to deter attackers. What’s more, plants can differentiate between acoustic energy that signifies a threat and sounds from non-threatening sources.

Research published in the journal Plant-microbe-animal Interactions demonstrates how plants boost the production of glucosinolate [1] and anthocyanin after being exposed to the vibration of a munching caterpillar.

Sound waves not only influence plants to bolster their defences; acoustic energy also affects plant growth and germination. Experiments have shown a massive difference in tomatoes subject to specific tunes; those exposed grew to be twice the size [2] of the control group. Researchers even found certain tunes to inhibit viruses in tomato plants.


Noise and music are entirely different phenomena. Both are forms of sound, yet feature different structures. Noise has no rhythm or structure, such as traffic noise, heavy winds, or the footsteps of a crowd.

In contrast, music features harmonising tones, rhythms, and melodies. Musical notes have their own frequency and belong to a specific scale. Each scale features simple notes that sound pleasant when played together. When played in a specific sequence, simple notes of the same scale form a melody.

Songs also feature unique rhythms, tones, and instruments. When two instruments strike the same frequency, they create a reinforced sound wave known as a standing wave.

Research shows that both noise and music can alter the way plants grow. A study published in the Journal of Integrative Agriculture documents that sound waves between 0.1 and 1kHz increased the yield [3] of peppers by 30%, the harvest of cucumbers by 37%, and the output of tomatoes by 13%. The same paper states that sound waves decreased the instances of spider mites, aphids, grey mould, and late blight.


Other scientists have explored the effects of music on plants, finding music to boost growth [3] and increase the presence of metabolites such as chlorophyll and starch. After comparing the influence of Indian classical music and rock music on China roses, researchers found the latter to stunt growth. Additional research found higher indole acetic acid levels [4] (a key growth hormone) in six varieties of vegetables after exposing them to musical acoustic frequencies.

Further studies found both rock music and classical music to exert a positive effect on seed germination, plant height, and number of leaves. In contrast, non-rhythmic traffic noises caused a negative effect. In contrast to this finding, another experiment found that any noise—when compared to silence—promoted growth in beans.


Growers go to great lengths to increase the output of their cannabis plants—from tried and tested fertiliser potions to extremely powerful lights and automated climate control. But does a DJ controller and a loudspeaker have a place in your grow tent?

Although quite a few studies have observed the positive effects of music on plants, cannabis has yet to be tested. However, cannabis shares the same biological mechanisms of growth as many other plants.

It does make sense that music could give your yields a minor boost. But we simply don’t know the best genre, how far to place the speakers, and how loud—or quietly—to blast your selected songs.

If you want to give it a try, prepare for some trial and error. Explore genres, volumes, duration, and tempo. Doing so will add a serious citizen science edge to your next grow, and you’ll be watering and pruning your plants while nodding your head, at the very least.

Studies have found music to increase the size, health, and yield of plants. So, should you treat your cannabis crop to some beats? Find out here.

5 Secrets to Growing Top-Shelf Bud

by Sirius Fourside

Have you ever had cannabis that was just…so so? Mediocre? Just okay? Cannabis that’s ‘just alright’?

Have you ever had cannabis that was so good, you want to save it so you can have it as long as possible? Cannabis so good that you inspect it closely as if you could somehow see why it’s so great?

What makes the difference between the two?

The look of the bud in addition to its potency, taste and smell is what makes cannabis seem top-shelf to the user.

But what happens when you’re growing cannabis that makes gives it these desirable qualities?

In this weeks issue of the GrowWeedEasy newsletter, you’re going to see what growing practices are responsible for making the difference between mid-to-low-grade cannabis flowers and top-shelf bud!

You’ve probably heard it a million times, but good cannabis starts with good genes. Having seeds with good attributes to work with gives you a plant that will flourish under the right conditions as opposed to just surviving.

All cannabis strains have their own attributes, so the best thing to do is to find one that fits what you’re looking for. Some strains are high in THC, some are known for tasting pleasant, some are high in CBD, etc.

In any case, growing cannabis from ‘bagseed’ is an easy way to lower your chances of growing great weed. In a best case scenario with bagseed, you’ll get a female seed as good as one from a seed bank. In a not-even-the-worst-case-scenario, you could get a male seed that grows a runt plant from a weak strain. Or even worse…it’s not even cannabis!

There are quite a few places you can go to get seeds with good genes, I’ve had the most luck and the least trouble with ordering from a trustworthy seed bank. Personally, I use Nirvana Seeds for their high-quality strains and I’ve got 100% of my shipments from them, but I’m also a big fan of seeds from Barneys Farm and DNA Genetics.

High Light Intensity

The amount of light your plant receives in it’s life can be used as a good indicator of how close it will get to its maximum potency when all other conditions are met. In fact, outside of genetics, light-intensity plays the biggest role in determining how big/hefty/potent your buds will be.

This means that even if you get seeds from a strain that is known to have 22% THC, the plant will need enough light to allow it to grow to this level of potency. This doesn’t mean that you need a 1000 watt HPS to grow great bud, but it does mean that you’re probably not going to grow top-shelf buds with a single 26 watt cfl bulb.

So much is enough?

Unfortunately, this is a question that is very difficult to answer as it depends on the specific strain you’re growing, the area you’re growing in, and the size of the plant being grown (smaller plants need less light). The general rule to go with is “more is better”, and watch your plants to see how they react. In most cases, it’s hard to give your plants too much light unless you have a high powered LED or a 1000 watt HPS.

Harvesting At The Right Time

For many growers, this is the toughest part to get right. Why?

Because you can buy seeds with awesome genes, and you can buy a MH/HPS combo that will flood your cannabis with light, but you can’t buy patience! And boy will a flowering cannabis plant try your patience!

Aside from becoming ever more picky about which nutrients they get, flowering plants will begin to smell ever-more enticing and look more and more ready to harvest. The problem is that there is a small 2-3 week window in which cannabis should be harvested, and most growers (myself included) get the urge to take them down prematurely.

Whenever your plants are flowering and you get the feeling you should harvest them because they look ready, reference this page and double check to make sure they are: Harvesting early is an easy way to ruin the buds you’ve taken so long to grow, so double, triple and quadruple check they’re they’re ready before you cut down a single bud!

Many growers consider drying and curing to be two parts of the same process, but I like to separate them to really underline the important steps involved.

It’s important to not only dry your newly harvested buds before they can be used, but you want to dry them as slowly as possible. Drying buds too quickly can make them crispy and harsh, and will make them smell – ironically – like cut grass.

A good way to keep moisture in the plant and keep it from drying too quickly is to trim the harvested branches after they’ve been dried. Having the extra leaves left on will cause the plant to dry slower since there is more actual plant to dry out.

Personally, I trim my buds before I dry them since it seems to be easier for me while trimming and when I’m cutting buds off of the stem. From there the buds can be hung up to dry, or placed on a drying rack.

In either case, I would recommend leaving on as much stem as you can as it slows the drying process, and is easy to remove later. I would also recommend hanging your buds upside down to dry before testing any other methods. Anecdotally, I’ve found that buds that retain their stems and are hung upside down to dry tend to dry much slower than on a rack…which is exactly what you want!

In short, dry your buds for as long as you can. Aim for more than 5 days, with a goal of 8-10!

Once your buds have been properly dried, the only thing left to do is cure your buds. This last step won’t add to their potency per se, but it’s largely responsible for the taste and smell we all love.

Essentially, curing your buds involves sealing them in an airtight container for at least 2-3 weeks. During this time, the jars are periodically jostled, opened, emptied and refilled with the same buds. This will give the buds to ‘get rid of’ certain not-so-tasty chemicals, and the jostling, emptying, etc. will help prevent mold from forming.

The Short Version

Here’s the meat & potatoes of this article in case you forgot any part of it(as some of us are prone to do):

Potent, top-shelf bud requires these 5 things:

  1. Good genes (Get good seeds)
  2. High Light Intensity (More light is better for your plants)
  3. Harvesting at the right time (You only get one chance; patience is key!)
  4. Slow Drying (The slower you dry your bud, the better)
  5. Proper Curing (Put them in a jar and let them out every so often until they’re done)

Great Bud Starts with Great Seeds!

What’s the first step in creating fat, potent, mind-blowing buds?


Make sure you start on the right path by beginning your next grow with a with a hearty, potent, higih yielding strain!

“Nirvana Aurora Indica is an F1 hybrid of Afghan and Northern Light. Its plants stay short, producing heavy colas and dense buds. This marijuana strain produces exceptional amounts of resin, resulting in a deep, near-black hash with a tasty aroma and a heavy buzz.”

“BlackJack produces hard buds with huge, grape-like calyxes that are completely encrusted with THC! The smoke is heavy and flavorsome, and produces an exceptionally long-lasting high.”

“Nirvana Wonder Woman is another one of those fabulous new high-volume marijuana plants. Wonder Woman bears rock hard buds which are easy to trim. The smoke of this cannabis variety has a classic, rich, skunky flavour accompanied by a long-lasting buzz.”
