Hall of Flowers hosted Freedom Grow volunteers, who contribute their artwork to raise funds for non-violent individuals incarcerated for cannabis-related offenses. Visitors can donate, write letters to prisoners in their gallery, or contact them through freedomgrow.org. All funds raised through their gallery directly supports Freedom Grow's prisoner and family outreach.

One notable exhibit is Andy's final handbag/backpack, crafted during his time in prison before his release. Alongside Andy's bag, the group art show also showcased works from:
