Quick Answer
Hanging transpiration bags are a reliable method for collecting drinking water in the wilderness. To be effective, transpiration bags should be hung from a sturdy branch at least 3-5 feet off the ground and 1-2 inches from the trunk of the tree. The bag should be positioned to allow full sun exposure and minimal leaf interference.
Choosing the Right Tree
When selecting a tree to hang your transpiration bag, look for one with a sturdy branch that can support the weight of the bag, water, and any debris. Avoid trees with smooth bark, as these can cause the bag to slip off. Instead, opt for trees with rough bark or branches that have a natural curve, allowing the bag to settle snugly.
Preparing the Transpiration Bag
To prepare your transpiration bag, fill it with 1-2 cups of water and a few handfuls of coarse, fibrous material such as leaves or grass. This will help to stimulate transpiration and increase water collection. Make sure the bag is securely tied and the opening is at least 6 inches above the water level.
Hanging the Transpiration Bag
When hanging the transpiration bag, tie it to the branch using a length of cord or twine. Ensure the bag is positioned to allow full sun exposure and minimize leaf interference. Aim for a spot that receives direct sunlight for at least 6 hours per day. In areas with high humidity or heavy leaf cover, consider using a mesh bag or a longer bag with a wider opening to increase airflow and water collection.
