I am in the same boat
@steam heat . The cost of juice was not that big of concern, so I DIY is/was low on my priorities. But, I did a lot of reading for familiarity. I started a list and have been starting to acquiring gear. So far,
I have acquired two liters of 100mg nic. I could get 3mg (my norm), but it just means I will use less of it because it is so strong. Therefore, a liter should last me 5+ years. Also, I got brown glass bottles to break down the liters into small usable bottles. Once everything gets frozen, I will just keep one 125ml brown bottle out of the freezer to use for making.
I am also getting lots of little juice bottles, a set of beakers and 1ml, 5ml, and 20ml Leur Lock needles. Also, found a pretty small funnel (tough to find).
I started getting my flavorings.
Everything is stored in darkness except the nic, and that is in the dark freezer.
I anticipate making one "flavor" at a time, but I am looking for probable ingredients.
Still learning, still preparing. I have about 500ml of vendor juice, so I have a bit of time.
Hope helps. Much more in the DIY forum.
