Dr. Greenthumb’s Insane OG Seeds Drop Globally June 19
BERLIN, June 17, 2025 /PRNewswire/ — Barney’s Farm, Amsterdam’s iconic seed bank, has joined forces with Dr. Greenthumb’s, the cannabis brand from Cypress Hill frontman B-Real, to debut a first-of-its-kind line of genetics that blends craftsmanship with cultural legacy.
30 Years in the Making
This collaboration has been three decades in the making. Derry Brett and B-Real first crossed paths in Amsterdam’s coffee shop circuit in the early ’90s. What began as a friendship rooted in a shared love for the plant now combines global influence with underground credibility.
This isn’t a celebrity endorsement—it’s a pledge to preserve a culture forged long before legalization, social media, or MSOs entered the scene. A partnership between two pioneers who helped shape the narrative before the world started watching.
Insane OG Goes Global
The debut strain, Insane OG, drops globally on June 19 at Mary Jane Berlin, Europe’s premier cannabis expo. Inspired by B-Real’s notorious 1998 anthem “Dr. Greenthumb,” Insane OG pays tribute to a counterculture built on resistance and dedication to the craft.
Bred from OG Kush, Bubba Kush, and Granddaddy Purple, Insane OG is an aromatic, indica-forward hybrid boasting 27% THC, delivering true connoisseur quality.
“Before anything leaves our house, it’s been stress-tested, verified, and refined to spec,” said Derry Brett, founder of Barney’s Farm. “We don’t release—we unveil. That’s the difference.”
The next drop, Cherry Bomb—a syrupy, high-yield hybrid—lands in September, featuring a pinene-dominant terp profile to enhance focus and mental clarity. More info coming soon.
Global Cannabis Movement
As legalization expands across the U.S., Europe, Asia, and Latin America, Barney’s Farm x Dr. Greenthumb’s has set a new global standard that honors the culture while prioritizing elite genetics.
What to Expect:
- World-class seed drops with international availability
- Certified nurseries for expert phenohunting
- Curated strain rollouts with long-term planning
- Lifestyle merch paired with each strain
“This collaboration is for the heads who’ve been with us since day one—before the hype and the headlines,” said B-Real, Founder of Dr. Greenthumb’s. “We helped build culture. Now we’re preserving it, one seed at a time.”
