Saw this today while cycling in rural Gallatin County, Kentucky. It's Kentucky's new cash crop, hemp. These fields used to be tobacco fields, now hemp is worth way more. But some are still growing tobacco...
It's supposed to be a fairly good cash crop. Just recently our current administration made growing hemp legal in all 50 states and it apparently is helping to fuel the current CBD /wellness craze. I'm not so sure all 50 states are going along with it though, but it will probably be a lucrative cash crop at least until there is a glut of product. If you can grow it for seed oil and plant fiber then it's a dual crop. Supposedly takes a lot less water than cotton, so there's that.
