Causes Of Tent Mould
Tent mould grows when there is moisture and warmth. It can damage your tent fabric.
Knowing what causes mould helps you stop it from growing on your tent.
Common Moisture Sources
Moisture is the main cause of mould on tents. Water can come from rain or dew.
Wet tents that stay damp for long periods allow mould to grow fast.
- Rainwater left on tent fabric
- Dew forming overnight
- Condensation inside the tent
- Wet ground or grass under the tent
- Humidity in the air around the tent
Storage Mistakes
Storing a tent while it is still wet causes mould. Moisture gets trapped inside folds.
Keeping tents in dark, damp places also helps mould grow quickly.
- Folding tents without drying them first
- Storing tents in plastic bags that trap moisture
- Leaving tents in basements or garages with poor ventilation
- Stacking tents with no airflow between them
