NatuDrain is a venting and watering drain (perforated flexible hose) which supports trees in their growth.
Until recently these drains were mostly produced from polluting PVC. NatuDrain is 100% biodegradable and compostable and does not contain any additives that are harmful to the environment. NatuDrain was developed in collaboration with the company Pipelife.
The size of the tree is the circumference of the trunk in centimers at 1,5 meters from the ground.
