There is lightweight but super strong building material that is made from mixing lime plaster and the leftover parts of hemp after the fiber has been extracted.
Madame France Perrier, contractor, builds about 300 houses a year all over Europe using this technique.
Hemp turns to stone, it petrifies, so you get a material that is stronger than cement at 1/6 the weight.
There are thousands of uses for hemp and the time has come for the U.S. government to legalize the growing of hemp so that we may benefit economically from this truly amazing plant!
