Believe it or not, numerous studies have indicated that playing music for plants really does promote faster, healthier growth. She determined that plants “listening” to rock music deteriorated quickly and died within a couple of weeks, while plants thrived when exposed to classical music.

Plants thrive when they listen to music that sits between 115Hz and 250Hz, as the vibrations emitted by such music emulate similar sounds in nature. Plants don’t like being exposed to music more than one to three hours per day. Jazz and classical music seems to be the music of choice for ultimate plant stimulation.

According to some studies, jazz music appears to have a beneficial effect, producing better and more abundant growth. The science television show MythBusters did a similar experiment and concluded that plants reacted well to any type of music, whether rock, country, jazz, or classical.

The popular Discovery Channel TV show, Mythbusters, ran their own experiment to test this and concluded that it is “plausible” that talking helps plants grow. They also determined that classical music and heavy metal music made the plants grow better than the control plants that received neither talk nor music.

Carrots should be ready for harvest about 60-80 days after sowing seeds, depending on the variety. The tops of the carrot roots will be about 3/4 to 1 inch in diameter and likely starting to pop out of the soil, though not necessarily. They will also be vibrant in color.

The obvious answer is that, like us, they see light. Just as we have photoreceptors in our eyes, they have their own throughout their stems and leaves. These allow them to differentiate between red and blue, and even see wavelengths that we cannot, in the far red and ultraviolet parts of the spectrum.

Although plants are a bit color blind, they do sense colors, more appropriately energy levels, that are entirely invisible to us humans. For example, plants can perceive far-red light.

Short answer: no. Plants have no brain or central nervous system, which means they can’t feel anything. Even though plants don’t have nervous systems, they can respond to stimuli.

In a study performed by the Royal Horticultural Society, researchers discovered that talking to your plants really can help them grow faster. 1 They also found that plants grow faster to the sound of a female voice than to the sound of a male voice.

While many plants release carbon dioxide, not oxygen, at night, having a few plants in the bedroom will not release enough carbon dioxide to be harmful at all. In addition, certain plants also filter harmful formaldehyde, benzene, and allergens from the air, improving air quality in our homes.
