Organizers of Santa Rosa’s Annual Hall of Flowers cannabis trade show and festival have announced that rapper and cannabis entrepreneur Wiz Khalifa will host a “Khalifa Kush Smoke Out” at the event on September 21st. In addition to this appearance, Houseplant by OCB, a collaboration with Seth Rogen, will be hosting a world record attempt to get the most joints lit in one place at the event. Hall of Flowers is a cannabis B2B event that has been held at the Sonoma County Fairgrounds since 2018, bringing dispensaries and brands together. For the first time this year, the second day of the event will be open to the public. Sonoma County has a long history of cannabis culture, in its proximity to the Emerald Triangle, and as the host of the Emerald Cup for many years.
