Scientists at Texas A&M AgriLife Research partnered with Growing Together Research (GTR) to collaboratively develop an industrial hemp strain with optimal traits, including reliably low levels of the psychoactive Delta-9 THC.Prior to harvest, industrial hemp grown in the U.S. must be tested to certify levels of Delta-9 THC do not exceed a 0.3% threshold. If the plants’ Delta-9 level is higher than 0.3%, the entire crop must be impounded and destroyed.Farmers must be sure their CBD, fiber or grain hemp crops do not exceed that threshold, which has kept many from growing the crop since it was first legalized at ...
