The biggest advantage of using hemp as a building material is that it is eco friendly and abundant if allowed to grow on its own. Beside providing carbon offsets while growing, the house itself continues to draw down carbon from the atmosphere. Mixing in the lime, allows the building to calcify over time, making the walls harder and more durable than the traditional wood or concrete used in building materials. Industrial hemp is not the same as the “how high” hemp. It is similar to bamboo in the fact that it regenerates itself very quickly and doesn’t require 40-100 years of new growth like tress do.
While it is an interesting concept, America still has a misconception of industrial hemp for use in building materials. The Hemp Growers of America have a very small lobby and very little money to convince Congress that using industrial hemp won’t turn entire generations into lazy, couch potatoes.
