Barney’s Farm today announced a landmark partnership that positions the company as the exclusive cultivator and distributor of Dr. Greenthumb’s premium cannabis flower and B-Real’s INSANE brand throughout California. The collaboration brings together globally respected cannabis innovators under a unified, craft-driven supply chain.
Through the new agreement, Barney’s Farm will leverage its award-winning genetics, scaled cultivation infrastructure, and statewide distribution network to strengthen product availability while protecting the quality and cultural integrity that define both brands.
“We’re partnering with people who live this culture, not just operate in it,” said Derry Brett, founder and CEO of Barney’s Farm. “This is the most exciting project we’ve taken on with an artist — hands-on, in the grow, deeply invested. It’s rare to find a partner who brings this much passion and history to the table.”
B-Real shared similar enthusiasm for the partnership. “California built one of the strongest cannabis cultures in the world, and this collaboration lets us keep raising the standard,” he said. “Consumers know our brands and trust our consistency. Working with Barney’s Farm lets us scale without compromising what makes these products special.”
Beginning in early 2026, all Dr. Greenthumb’s and INSANE cannabis flower sold in California will be produced exclusively in collaboration with Barney’s Farm, which has secured the exclusive cultivation rights for both brands. These products — including new, co-developed genetics — will be available at retail locations throughout California.
