It's now legal to grow industrial hemp in a bunch of states, but the DEA is still refusing to allow it.
Yep, until the Feds get their collective heads out of you know what, hemp isn't going to be a viable competitive commodity in the US, even in states that have legalized it...
The best alternative we can get affordable in the US if you don't want to use wood chips would be ground corn stover, but at least in my area the farmers don't even bother harvesting it as there is little market for it, instead they just till it back into the ground...
