So, its essentially like light clay straw with a lime stabilizer and maybe some MgO? Any cellulose material will work? The part of the hemp plant they are using is a byproduct of fiber processing. I do not see that it would have any particular advantage over other things like wood chips, straw, rice husks, cattail leaves, etc. Hemp is trendy, so there is a strong marketing angle. Importing processed hemp byproduct to be"greener" is a contradiction (same with shipping straw bales or rice husks). Use what you have locally.
