Hempcrete is made from hemp, water and lime. It is “non-toxic, mold-resistant, mildew-resistant, non-flammable, formaldehyde-free, and perfect for people with chemical sensitivities.” It weighs seven times less than concrete and insulates so well that heating and cooling costs are about half that of a normal house.
Due to our brain dead drug laws, the hemp must be grown elsewhere then imported here. Sigh. Look, hemp has a THC content of approximately zero and can not get you high. It has been grown for decades in Europe and Canada but is still banned here.
Jetson Greene wants to encourage the growing hempcrete movement. So do I.
