Blue River™ AVD Seed batteries are designed specially for Blue River™ Solvent-less Rosin Sauce, Live Rosin Sauce, Jelly Sauce, and Jelly Cartridges. The AVD 510 cartridges are made from lead-free parts in a glass casing powered by a ceramic core delivered through a custom ceramic bullet tip to maximize true flavor. The Blue River™ AVD 510 Seed platform delivers the best-in-class farm to table cannabis experiences. The screw on magnetic attachment can be adjusted to increase air flow to the holes located on the bottom of the cart by turning the cart counter clockwise while it is magnetically secured in the battery.
