Kats Botanicals CBD is produced using full-spectrum hemp extract containing less than 0.3% THC. The hemp grown to produce their products is farmed in Colorado at 8,000 ft — the first hemp flower that we know of to be grown at high altitude. Their farmers operate under strict guidelines, trucking in nutrient-rich soil and fertilizer for their fields. They use drip irrigation using only organic nutrients, with no weed or pest control whatsoever. Their whole-plant approach means their CBD contains additional cannabinoids and nutrients found naturally in the hemp plant for maximum benefit.
