Question: Do I need to ventilate the tent?
Answer: To stay dry in your tent you not only need to seal the seams, but you also need to ventilate your tent. If you sealed the seams properly, your tent should now be waterproof enough to keep the rain and dew out. That means it is also waterproof enough to keep moisture condensation in. As you sleep your body gives off moisture through perspiration and breathing. This moisture condenses on the inside of the tent walls, inside and on top of your sleeping bag, and on the tent floor. It's no fun waking up wet. Most tents provide a roof vent and doors or windows with screens. To avoid the buildup of condensation simply open your roof vent and zip a door or window partially open. If you have no roof vent, crack two doors or windows open. Either way will create a slight cross breeze that will help to remove body moisture and prevent condensation inside your tent.
