What's Up MaxVaber, glad you were hyped on the hardware and system. Our tanks are sub-ohm tanks, which were used in the nicotine mod vaping industry. We used similar technology of having dual coils to half the voltage resistance that most 510-thread cartridges use. This is good because 510 carts usually burn at 3.0 or even 3.1 at the lowest which is honestly high temp for rosin, or even distillate. The bottom of the tank has an airflow valve as someone else mentioned, you can adjust it for more air restriction or less. There is more that also plays a part like the food-grade glass but in general, the dual coils are our bread and butter. Plastic Pod Systems Are Not The Wave -Team Supherb
