and you can watch the documentary The Secret Life of Plants from 1979 based on the book with a soundtrack by Stevie Wonder here at the Farm right now....and " The Secret Life of Plants "
i read the same grow study but I dont think it was death metal... it was a combination of Nirvana's "Bleach" and Lou Reed's "Coney Island Baby"i read a post years ago, by a guy claiming to have done a purely scientific grow study on his plants and their reactions to different types of music. he claims that they responded better to death metal, than to any other type of music. ...i wish i had a link to that post.
i play lots of death, in flames, vader, relapse compilations ..as well as nofx, the distlers, misfits, d.i.....lately though, my girls have been listening to a lot of trip hop. i hope they like the bass.
