@Dannysum - You don't say what atomizer you're using. If you bought the H-Priv starter kit, you probably have the TFV4
tank, which should be able to handle pure VG. If it doesn't wick well enough when you try it, just add the distilled water a drop at a time to your 30mL bottle, shake and try again. You won't need much of it to thin the VG, and there are no harmful effects.
DISCLAIMER: This should go without saying, but
don't try to vape distilled water by itself. 100C steam would be harmful. And it just might leak out of the tank and into your device, and you don't want that. Plain water and electricity don't mix in vaping. Harmful, yeah.
