How to make a hempcrete wall


The development of hemp in the United States has been ridiculous, because idiot politicians thought it was the same thing as marijuana (it's not) and banned it back in 1970 as a Schedule 1 drug. In actuality, though hemp is a variety of Cannabis sativa, it has less than a 0.3% concentration of THC, the psychoactive ingredient that you need to get stoned. (Marijuana has a 5%-plus concentration.) Nowadays, thankfully, open-minded materials scientists and builders have discovered hemp's value as an eco-friendly building material. As host of the UK's Grand Designs TV show for nearly two decades, British designer Kevin McCloud has seen his fair share of building techniques and materials.
