I would like to have a few opinions on mixing from some more experienced in mixing than myself. What should I expect for a 75pg/25vg in aspects such a TH and vapor production? Has anyone found a good place to buy large bottles with child proof caps in the 400ml range or so? I would like to find locally if I can, not order online, has anyone found at a pharmacy or such I havent tried yet. I want the large bottles so that I can pre mix my nicotine then use that bottle to store then move that into smaller bottles to then add my flavors. I have read a few posts that say they freeze or refrigerate the nic is this clearly a necessary storing option? I am new to DIY liquid however I am not really a novice to the vaping community or the idea of mixing I have just not done it for myself yet.
