In 2014, President Obama signed a version of the Farm Bill that established the Hemp Pilot Program, allowing certain research institutions to cultivate and study hemp. And in 2018, hemp was officially legalized on the federal level.
The states where it’s
legal to grow hemp in 2019 far outnumber the ones that have not passed legislation to allow residents to tap into the booming cash crop.
In fact,
only three states currently allow no form of hemp farming: Idaho, South Dakota, and Mississippi. The rest of the United States allows for the cultivation of hemp via commercial, research, or pilot programs.
My BIL is a farmer in Michigan and recently attended a seminar to learn about growing hemp on his farms.
I was looking online out of curiosity and there are commercial hemp seed suppliers in the US where you can purchase bags of viable hemp seeds by the pound. An ounce of hemp seeds probably runs around 4,000 to 6,000 seeds.
Currently, you can't grow hemp in South Dakota, but I lived there for four years in the late 80's to early 90's and feral hemp grew everywhere. From one large plant you could harvest thousands of seeds. They grew hemp there legally during WWII and it would be nearly impossible to eradicate it. They didn't even try. It grew in every ditch in the town I lived in and it grew in in every vacant field along fence rows on farms.
