How Fast Can Mold Grow?
It is an established fact that mold can be harmful to human health. Unfortunately, human exposure to mold isn’t as rare as it should be. Many households suffer from mold growth because the fungus can grow easily. Mold can be found growing in almost every area of a house including the ceiling, behind the walls, under the floors. Molds thrive in conditions that are favorable to humans as well, making the task of cleaning up mold that much more difficult.
Now, coming to the question of how fast can mold grow; well, the answer is mold can grow in a span of just 24 hours. With the right amount of humidity, air flow, and temperature (3 degree Celsius or more) you can be sure that there will be mold growth in your home.
How does mold grow?
As mentioned above, mold spores need the perfect combination of a nutrient source, warmth, and moisture in order to grow. So you need to keep an eye on your basement, bathroom, and crawlspace. These locations, more than others, tend to provide suitable conditions for mold growth. For instance, if you have suffered recent basement leaks, then you can be sure that there is build-up of basement moisture.
The moisture combined with the generally warmer temperatures of the basement and an organic food source will most certainly prove to be ideal for mold growth. An organic food source would include wood or drywall. In fact, drywall surfaces experience faster mold growth than wood.
If the above factors exist, you can expect the mold to show up anytime between 24 to 48 hours.
If you spot mold patches, that’s a sign that the mold has begun growing. If it’s growing, then it also means that it will reproduce by spreading the spores. Mold colonies will begin to show at the rate of 1 square inch each day and if ignored, they will cover a much larger area in as little time as a week.
Mold in winter
Though the temperature conditions for mold growth need to be warmer, the truth is that they can even grow in winter. That’s why we can find mold growing even in our refrigerators. However, common household mold does not grow in temperatures below -15 degree Celsius. However, the problem is that most household temperatures are maintained at 5 degrees or more, which will encourage mold growth.
