I have been storing my pg and vg along with my flavors in the fridge. Is this ok? How long are they good for? I store the nic. In the freezer. How long will it last and stay potent. After I make up the e. juice where should I store it? How long will it last unopened. I have read that you need to let it sit several weeks before using it to let it steep. Is this correct? Will setting it in hot water speed up this process? Just some questions I have encountered. Any help would be appreciated.
