You can use any type of hash, rosin preferred. Form it into a shape that you can drop into the hash chamber easily or stick it to the bottom. Heat the rod for 30-45sec at least. Wait about 2sec and dip in, take the first rip while letting the rod sit in the chamber to spread heat. For continuous smoke, lift the rod above the holes but not fully out of the top in order to create the airflow while dipping back into the oil to activate it. Reheat and dip in until it’s finished or reheat later! AMAZING PIECE JUST NOT MY CUP OF TEA, HEATING ROD COMES WITH IT JUST NOT IN THE PICTURE!
