The effects of sounds on plants have been being studied for decades. The results are hard to interpret because no matter how strict one is with a control group there are always pesky variables. I found that episode of mythbusters but I also found some guy named David Hershey online who made a list of interesting critiques on their methods. They are as follows:
1. No statistical analysis.
2. There was only one small greenhouse per treatment so no real
replication to take differing environments into account. A plus was
that there were ten pots with one seed per pot in each greenhouse.
3. One seed per pot was an unwise technique because some of the pots
ended up with no plants due to germination failure. The usual technique
for an experiment of this type would have been to plant three seeds per
pot and then thin to one seedling per pot.
4. Not all greenhouses were oriented in the same direction so light
patterns within the shaded structures could have differed and affected
the results.
5. An LA rooftop in mid-summer provided poor growing conditions for
plants, especially for peas, a cool season crop.
6. The control greenhouse was in the center of the roof. The treatment
greenhouses were closer to the edges. That could have resulted in
significant temperature differences.
7. The automated irrigation system failed midway through the experiment
so plants were harvested early and fresh weights measured. Plants in
some treatments were clearly affected by lack of water more than others
so that skewed the results. It would have been more logical to measure
plant dry weights because about half the leaves on some plants were
dead and dry.
8. There was no attempt to determine a mechanism that would explain why
plants would grow better with sound.
Their experimental errors indicated how easy it is for students to do
experiments on plants and sound incorrectly and reach wrong
conclusions.
I think a tv show fighting for ratings is not to be taken as gospel. In the 70s some lady named Dorothy Retallack wrote a book about her findings and she concluded that classical music had a more positive effect than rock music. I think its safe to say that the verdict is still out and for now I will continue to provide my sexy ladies with righteous tunes.
i really dont think the music matters.. its pretty much impossible to tell if it helps marijuana.
i have had a m/2 full of master kush. and gotten around 200g/m2 and a few feet away was another m/2 of master kush and i got a little over 300g/m2. a 600w hps over both...everything was the same.. the fact is that shit changes, not all plants are equal, even if they have the same genes. go ahead and provide music for your plants, it might do something, but aas someone said earlier, it often leads you to take better care of your plants. i just think it is a waste of time.. but to each there own...
Maybe i should let my plants watch It's Always Sunny in Philadelphia.. if i was a plant, that would make me happy.
