Hemp farming exploded after the 2018 Farm Bill passed last December. The bill decriminalized the plant at the federal level, opening the door for many U.S. farmers to grow and sell hemp.

Over the past year, licensed hemp acreage increased more than 445%, according to the advocacy and research group Vote Hemp. More than 510,000 acres of hemp were licensed in 2019, versus about 112,000 acres in 2018.

At the same time, products made with cannabidiol — a chemical compound found in hemp — are being sold everywhere from gas stations to CVS. CBD is promoted as a cure-all for anxiety, depression and post-traumatic stress disorder, even though the science isn’t there yet.

Farmers see an opportunity to get in on the “green rush.” But now, some are worried that their first harvest could leave them empty-handed.
