What about hempcrete?

Hi Kiai, thanks for weighing in. But I would not put hempcrete in the floor of a tiny house. It has its place in the green building community, but hempcrete does not have a particularly high R value per inch and is extremely heavy. A tiny house on wheels already has a pretty high carbon footprint per square foot of living space given the fuel costs of pulling a house around and limited room for insulation, adding unnecessary weight would make that even worse.
