Grandmaster Chem, commonly known as “Chem Master,” is a rare 50/50 hybrid strain developed by combining the iconic Master Kush and Chemdawg D strains. Grandmaster Chem is just what you need when it comes to hard-hitting hybrids. With a THC content of around 23-28 percent on average and effects that can last for hours on end, this bud is incredibly potent. The high begins with a surge of cerebral effects that tear through your mind, leaving you with a sensation of concentrated energy and motivation that easily erases any unpleasant or racing thoughts. As your mind rises higher and higher, a tingling sensation will develop in the back of your mind.
