If you can find PG mix it with some wax with some heat a quick stir and it should pour right in to your tank. I would recommend using one of the dab jars that are food grade silicone. I use the TAO by OM jars. What your going to do exactly is take your wax put it at the bottome of the container then take a very small amount of PG and put on top of the wax. Obliviously the less PG you use the more potent your tank will be. I would recommend just using enough to make a somewhat liquidity consistency. after that you are going to want to take a heat gun $10 from home depot or a torch and slightly heat up from a distance without burning the material. At the same time you are going to also want to mix with a dabbing tool. Then simply/ carefully pour into the ce4 tank. do not use a ce5 tank it wont work good. YOu can find some of the PG mix at https://www.headimedies.com/ its good quality stuff.
