Rosin Tech Labs operates a state-of-the-art production facility in Torrance, California, where they produce premium solventless concentrates exclusively for the California market. Their product lineup spans multiple categories, including live rosin concentrates, Hash Holes (infused pre-rolls), Rosin Bars (solventless vape cartridges), Hash Nugs (rosin-infused flower), and Hash Walkers (infused pre-roll packs).The brand offers two distinct product tiers. RTL Black Label represents their award-winning, small-batch line featuring ultra-rare cultivars in batches under 1,000 grams—often released just once annually with limited comeback drops. RTL Green Label provides the same solventless quality and extraction process but sources more prevalent, high-yielding cultivars in larger quantities, making premium hash more accessible to conscious consumers.Rosin Tech Labs partners with California's top heritage farms, including LUMA California, Emerald Queen Farms, Valley Grove, Huckleberry Hill Farms, Happy Dreams Farm, and Savage Farms. Every product is crafted using only water, heat, and pressure—never butane, alcohol, or chemical solvents. Their extraction process utilizes their proprietary Rosin Tech presses, ensuring precise temperature and pressure control for maximum flavor and potency preservation.
Rosin Tech Labs' journey began in 2015 in Bethpage, New York, when solventless extraction was still in its infancy—beyond hair straighteners and parchment paper. The founders started Rosin Tech Products in 2016, creating extraction equipment that would empower cannabis enthusiasts to make their own concentrates at home. What began as two founders working nights in a tiny garage, hand-assembling rosin presses with passion and determination, quickly evolved into something bigger.As the solventless movement gained momentum, the company expanded westward, relocating headquarters to Los Angeles. By 2018, their love for hash led them to take the next step: they started the licensing process and launched Rosin Tech Labs as a cannabis brand. The team outfitted their Torrance, California facility with their own award-winning equipment and began producing the type of premium hash they loved to consume themselves.Over the years, Rosin Tech Labs has earned numerous High Times Cannabis Cup awards, from Best Booth to Best Product. Today, their products are available in over 200 California dispensaries, and they continue to push the boundaries of solventless extraction while staying true to their roots as hash enthusiasts, educators, and advocates.
Rosin Tech Labs is driven by an unwavering commitment to advancing the art of solventless hash-making. Their core mission centers on producing the highest-quality hash they would personally consume, never compromising on purity or process. By harnessing only water, heat, and pressure, they deliver concentrates that preserve the full spectrum of terpenes and cannabinoids without introducing any chemical solvents.Beyond production, Rosin Tech Labs serves as educators and advocates for the solventless community. They actively participate in cannabis events throughout California, sharing their expertise and passion with enthusiasts and newcomers alike. The team believes that being authentic members of the hash community—not just industry players—is essential to their success. Their values emphasize selecting unique genetics with distinct terpene profiles, partnering with passionate heritage farmers who prioritize plant wellness, and maintaining small-batch, artisanal methods that ensure every gram meets competition-grade standards.
At Calm Effect, we're genuinely impressed by Rosin Tech Labs' commitment to the craft. This isn't a brand that jumped on the solventless trend—they literally helped create it. Starting as equipment manufacturers who built the presses themselves gives them an unmatched technical understanding of the extraction process, and it shows in every product.What really sets them apart is their transparency. They openly share which heritage farms grow their flower, explain their washing and pressing techniques, and even detail the difference between their cold cure, fresh press, and solventless diamond methods. The two-tier system is brilliant for deal-seekers: Black Label delivers ultra-premium, limited drops for connoisseurs, while Green Label offers the same solventless quality at accessible prices without cutting corners.For consumers who care about purity, appreciate genuine passion, and want to know exactly what's in their concentrates, Rosin Tech Labs represents everything we love about craft cannabis.
