Testing THC In Hemp
There's plenty of ‘hemp hype’ in farm country, but there have been some challenges, including making sure the THC level stays low enough to keep it legal.
Politico reports the legal threshold is 0.3 percent; anything above that classifies the crop as marijuana. Hemp growers are calling for a national testing standard on measuring THC. USDA says it will release federal guidelines for hemp ahead of the 2020 growing season.
