To all ejuice lovers and vapers. I wanted to introduce myself! I have been vaping as of the last two years. Thanks to ........... and many other sites I have not mentioned yet. I was able to quit a pack a day habit of 10 years. I am grateful for this site and forum. I aspire to have my own little site with recipes, blogging and juices for sale. For now, I am learning and reading as much as I can. A few things. I noticed that the TPA/TFA forum has not been updated in a while. I wanted to know if anyone out there is a big fan of the DIY e-juice and if you buy from TPA formerly known as TFA. If so, can anyone help me to getting the appropriate information on ratios and perhaps even an average mean of what is best for measuring drops to ml's. In other words, what is the mean or average drops per 1 ml for a glass dropper or a pipette for instance or does anyone have a chart they use for each purveyor such as TPA/TFA, Flavor West, etc....??
