The microorganisms

Origin and cause of algae and fungal attack

In our latitudes, we have a very high humidity, which can promote algae and fungal attack on a tent cover. To prevent premature infestation, all our fabrics are impregnated and pretreated against mold fungi.

Nevertheless, the location and the care by the owner are crucial for a long life of a natural tent. Here you can learn more about the probably oldest microorganisms on our planet and how you can prevent an infestation of your natural tent.

Algae and fungi have adapted in their development optimally to the living conditions on earth. They can be found on almost all surfaces such as stone, wood, glass, metal and even on fabrics.

What are algae and how do these green areas develop?

The habitat of the algae is mainly the water. During evolution, algae evolved to adapt to life outside the water. The cells of the algae are about as large as a dust particle and are carried by the wind on the surfaces, where they finally settle. If the algae cells on a certain surface have been in contact with water long enough and they find enough nutrients in the water, they begin to multiply. The algae do not die off even during longer periods of drought. They dry and fade, but recover at the next wet period.

What are molds and how do they arise?

Mushrooms and molds consist of cell threads and spores. The main habitat of mushrooms is actually in the soil, where they serve to decompose organic substances. In contrast to the algae, fungi can not only live on air and water because they do not photosynthesize. They do not appear as green areas, but usually only as small black spots or foxing. The mushrooms absorb their nutrients from the organic substances from the surface they inhabit. Either the nutrients dissolved in water or the fungi excrete enzymes, with which they can liberate the nutrients from the underground.


If the environment is extremely humid for a long time and the nutrient supply of organic substances is favorable, the cell threads grow and branch into a network of threads. The fungal spores then form at the ends of some cell threads for multiplication. These spores are distributed by air movement. In our air, 96% of the biological particles consist of fungal spores, which are an ideal substrate for their reproduction.

The impregnation of the tent fabrics ensures that the moisture drains off faster and does not penetrate the fiber. In addition, if the substances are treated against mold fungi, they will have a longer lifespan and will delay the algae and fungal attack. However, the best impregnation and equipment will decrease with the weather and therefore early care and refreshment of the impregnation is important!


Which conditions promote algal and fungal attack?

In general, there are many fungal and algal colonies on trees, whereby the pressure of infection by algae cells or fungal spores near trees is particularly high. Due to the permanent evaporation of water from the leaves of the trees, the humidity in their environment is higher and favor the growth of algae and fungi. The following points promote early infestation:

  • Shadow through trees or houses
  • High humidity near water or fog
  • Moisture from the soil in moorland
  • Biological residues on the material, such. Bird droppings, pollen and leaves
  • Rural environments (are good breeding grounds for algae and fungi)
  • Long periods of precipitation in autumn / spring
  • Locations with restricted air movement

Mostly west and north sides are more affected. The north side receives less sunlight and is therefore rarely completely dried. The west side, however, is often wet by rain, as the main wind direction mostly pulls from the west. On the south side, algae and fungal colonies are less likely to be found thanks to the strong sunshine. The tent cover dries faster there and the strong UV rays kill the algae cells and fungal spores rather.

With what measures can I avoid algae and fungus?

  • As location choose an open, sunny plain
  • Keep distance to trees and bushes
  • In the rainy season, heat the tent more often with a fire
  • If possible, occasionally dismantle and disassemble or move rods
  • Remove bird droppings and other organic residues from the hull
  • Cut back the grass and spread wood chips around a tent
  • Early cleaning and care

If you follow some of these measures, you will enjoy your tent cover for a long time. If you are unsure about the location, let us advise you. We know from experience which material is suitable for which location or use
is best suited.
