Throughout the wash process there are 3 collections of trichomes. 90u Rosin is made from the very first collection. This is where the most terpenes come through. The terpenes of any strain shine through in 90u rosin. Since 2020, we have taken a small-batch approach to cultivate, wash and press everything in-house. Dedicated to producing the highest quality solventless products to add to our constantly evolving genetic library, we oversee every step of the process through our integrated cultivation and extraction facility. Not all solventless is created equal.
