Hemp Technologies said it wants to use hemp-based materials to construct a 500-square-foot structure at the ruins of Knapp's Castle near Santa Barbara. The principal material for the project is Hempcrete, made of the woody internal stem of the Cannabis sativa plant, which is processed into chips and mixed with a lime-based binder. That concoction is then sprayed on, poured into slabs or formed into blocks like concrete to create the shell of a building. — latimesblogs.latimes.com
