Is mold a plant or an animal? And why it matters.

Understanding Mold is the Basis to Prevent Mold

Mold is not a plant and not an animal. Mold is a fungi with its own unique life-style, starting from a tiny microorganism called spore. Not all fungi are as unwanted as mold. Some are great decomposers, where decomposition is wanted. Antibiotics such as Penicillin are fungi, their development is a blessing for people. Even in our food we welcome the distinctive taste of yeast-fungi when brewing or baking.

But mold in residences and offices is not welcome, and it presents a danger for the building and for the people living in the building.

Mold starts from spores. Spores have been around for centuries, our environment is contaminated with spores. That’s why mold can develop everywhere under the right conditions, even though nobody put “mold seeds” out.

Let’s take a look at how mold grows: A tiny spore is dormant somewhere, waiting sometimes for years for the right conditions. If the right conditions occur (see below), a spore will develop into a new organism.

The new organism develops into mold by penetrating through and under the surface into the substrate looking for food and growing an ever-extending web along the surface as far as favorable conditions exist. From this web tiny extensions grow vertically up. The ends swell and new spores are produced. When the spores are ready, they are air borne by the millions and dispersed into the surrounding air. The slightest drift can carry the spores far away in a short time, where they will, if conditions allow start a new colony.

Four ingredients have to be present for mold to grow: food, water, air and moderate temperatures that Panama experiences.

First red flag: Food: Contrary to green plants, the food source for mold is carbon, extracted from the material the mold lives on. As mold extracts carbon, it destroys carbon-containing substances: organic materials such as wood, wood-based products as well as plastics made from petroleum products, paint, etc. as well as building materials such as concrete and sheetrock. Mold infestations can have catastrophic consequences by weakening or destroying structural elements in buildings.

Second red flag: The destruction of materials is not all. While digesting its food, mold releases toxics into the air, which can present a health hazard to humans.

Third red flag: One mold colony can grow countless spores sent into the air and inhaled by people living in mold infested areas. Mold can be a health hazard, depending on the type of fungi very serious health problems have occurred. Plus, the smell is revolting.

As mentioned before, in addition to food, the fungus needs water, air and moderate temperature.

In order to absorb food and grow, mold needs a certain moisture in the materials it likes to eat. Not too much and not too little. The fungi will not grow, if submerged in water, the fungi also cannot grow on dry materials. The moisture has to be a moisture content equivalent of 80% relative humidity to 99%, but not standing water. Example, if the relative humidity is 80% and the temperature is at 700F, the equivalent wood moisture content is 16%, which is considered a threshold for mold concerning wood.

Summary: Spores are everywhere, ready to develop into mold. Mold needs food which is a main substance of all building materials. Humidity in air and moisture content of the substrate the mold grows on, are critical and have to be in a range from 80%-99% and Wood moisture equivalent of 16% and above. And, the climate has to be moderate. Considering all these factors individually, we can really only control the air humidity and the moisture content to reduce the danger of mold growth.

If all is well, we live in dry buildings, kept at a comfortable relative humidity and temperature. Mold cannot develop, because the building is dry, the food source is inaccessible for mold and its spores.

This all changes when humidity levels increase above 60%, when rain leaks in from outside, when a condensation forms on walls, floor or ceings from air conditioners. There is a time slot of 24 hours to a few days, when something can be done before the mold gets a foothold. Mold remediation specialists can assess the humidity and moisture situation, suggest a mold remediation program and advice on ongoing humidity and mold management practices.
