A hemp blend (also called hemp shake or hemp trim) is finely milled industrial hemp biomass. Professor Herb Premium Hemp Blends are six-times filtered to remove as many stalks and seeds as possible, then cured for a minimum of 96 hours in humidity and temperature controlled rooms before being infused and packed in the UK. They contain zero nicotine, zero tobacco and are lab-tested to stay within UK THC limits.
