Hemp as a building material has been used across Europe for centuries, and as a modern building material, industrial hemp is now grown by certified commercial growers. The strain of plant grown for hempcrete contains 0.3% of THC, the ingredient in cannabis that provides its psychoactive nature.
The basis of hempcrete is hemp, the balsa wood-like core (or ‘Shiv’) of a cannabis sativa plant.
