When you smoke the Deadhead you get a nice cerebral high but its not to racy, you also get a nice relaxed feeling within the body. It is a mellower sativa with a nice earthy piney smell and taste.
Crystal Chunk is a very heady Indica. The strain relaxes the body but you are still able to function. The smell really gets you in the nose and has a little bit of a kick. There are beautiful red hairs, laying against the dense lime and dark green flower. Check out that Crystal.
