Jetty Cold Water Hash Pre-Rolls start with top-shelf bud (no trim!), greenhouse-grown by our small farm partners using organic and regenerative farming methods. An infusion of cold water hash comes next, made in-house using just ice and water. Once dried and sieved, our hash has a fine granular consistency that infuses perfectly into the flower. The result is a curated pairing of flower and hash that’s tasty and potent, with an even burn right to the end. -- Top-shelf bud. Curated flower and oil pairings. Supercharged Potency.
