Hello guys, I'm new to subohm vaping and I just purchased the joyetech delta 2 (0.5 ohm standard heads) with the smy60w box mod. I'm going to be using this with my favorite 50vg/50pg grey matter e juice from mistereliquid and I wanted your advice on what wattage I should be vaping at and how open the juice control valves on the coil head should be and how open the air control should be. I'm going to be taking deep lung hits if that helps. Thanks in advance and I really do appreciate it.
