What does Dry Ice mean?
Cardice, commonly referred to as dry ice, is essentially solid carbon dioxide (CO2). It is found at temperatures below 194.65 degrees Kelvin and turns into liquid carbon dioxide when it reaches temperatures above that. Dry ice is useful in numerous fields of physics, engineering, mathematics, biology, chemistry, and agriculture, among others.
In indoor gardening, dry ice is said to be a way to provide extra CO2 to your plants, but it has severe limitations and is not a common practice.
Although plants in your garden and the majority of the botanical kingdom create their own food, they require certain components as raw material to photosynthesize. Carbon dioxide is an important one, and if the environment surrounding your garden lacks it, as indoor environments often do, plants will not grow properly and will become unhealthy.
Dry ice is a form of CO2 supplementation, but it has its pros and cons. Though it is an organic method of CO2 supplementation, it is labor intensive.There are several ways to do this, but the easiest and most common one is the limewater test.
Symptoms of CO2 deficiencies in your plants show up when their leaves change color, mainly purple or brown, and stems and roots dry up. To prevent this, first test the level of carbon dioxide in and around your garden. If you discover that your plants lack carbon dioxide, just put on a pair of insulated gloves, break the dry ice, into tiny bits, and scatter them around your plants. Although it sounds very simple, do not remove the gloves and do take a few extra precautions.
