That could possibly be about to vary. At current there’s nonetheless no hemp provide chain in place for the merchandise to go from farms to those that could make it into hempcrete or hemp lumber. Smaller corporations try to try this although, so it is probably not too lengthy earlier than we begin seeing extra hemp houses within the U.S

“Inside the subsequent few years you’ll start to see hemp houses and hemp options for lumber, concrete and metal,” Steve Streetman wrote in Assume Realty. “When a product is best, cheaper and sooner, in addition to extra environmentally pleasant, it will probably’t be held down for lengthy now that it’s authorized and the foundations for rising it have been developed.”
