Known as “The Nighttime Strain” and bred specifically with pain relief and sleep in mind, Granddaddy Purple was introduced by Ken Estes in 2003. This nearly pure indica strain quickly took first place in cannabis competitions in 2004, 2005, and 2006 and has remained extremely popular, especially for those seeking to get a good night’s sleep. The high begins as a pleasant head buzz rapidly giving way to deep pain relief. In higher doses Granddaddy Purple can offer sedative effects but in general this is a good choice even for the novice.
