Elite grower and industry pioneer Josh Del Rosso has cultivated the OG Kush varietal since the mid-1990s and helped launch this potent plant to legendary status. Josh’s OG Kush not only became the very fabric of LA cannabis and pop culture, but fueled a west coast phenomenon for the last two decades.



The Original: Josh D and OG Kush


Josh Del Rosso’s star-crossed affair with OG Kush began in 1996 when his friend Matt “Bubba” Berger shared a cutting from this now legendary varietal.


A cannabis cultivator, Josh knew pure potency when he experienced it. The gorgeous diamond-studded flowers of OG Kush put off a dynamic, layered aroma so unique, with effects so equally rare, that Josh became determined to dial in grow techniques for this one-of-a-kind plant. And it’s a good thing, too—devotion would be a requirement for the hard-to-grow, low-yield Kush.


The late 1990s was a catalytic time for indoor cannabis cultivation in California. The medical marijuana initiative, Prop 215, had just passed and Josh and his crew of underground cannabis growers were in pursuit of indoor hydroponic perfection in the Hollywood Hills and parts of the San Fernando Valley. They shared information, equipment and know-how and their breakthrough grow techniques were a perfect match for the finicky Kush.


Josh’s OG Kush—the OG stands for Original—caught on like wildfire and became the most potent, sought-after flower around. Today the plant serves as the cornerstone of top-shelf cannabis and has inspired decades of experimentation.



California Grown and Crafted


Our plants are grown with love in beautiful Santa Barbara County where the balance of sunshine, temperature and humidity provide the perfect conditions for our grow. Our 120,000-square-foot facility boasts a state-of-the-art hydroponics system and a mixture of sun and supplemental lights that allow our plants to flourish.


Our devoted team takes prides in the meticulous attention paid to every step of the process. Our harvest technique captures the bud at its peak ripeness for maximum density and flavor. We never use pesticides or herbicides or chemicals, but prefer biological control to care for the health of our plants, our customers and the environment. And Josh personally ensures that every bud lives up to its top tier reputation.



Calyx Peak & Josh D


Calyx Peak Companies is building a family of premium adult use and medical cannabis brands. Central to our vision are quality, integrity, craftsmanship and community. No one embodies these qualities more fully than cannabis legend Josh Del Rosso, the man who has set the bar for the art and science of cultivation for over 23 years.



OG Kush is known for its pure potency which sparks an unparalleled expansive, inspired and long-lasting experience for new and veteran cannabis users alike. The plant’s genetics stretch back to the Hindu Kush Mountains of Afghanistan and serve as the cornerstone for countless Kush hybrids that have been inspired by its tried-and-true effect—a heady euphoric and energetic clarity with a full-body floaty feel.

The purest way to experience the full spectrum of the plant remains the original method—to smoke it. While myriad alternatives have emerged to enjoy cannabis, the majority of users prefer to inhale. As legacy and purity are a hallmark of our mission, we are proud to deliver a heritage flower with unprecedented power. OG Kush conjures a pungent fuel aroma with keynotes of lemon citrus, pine and anise undertones.
