Hi everyone,
I put this in beginners because it seems like a basic question which I’m sure people here would be able to help with. I’ve been making juices for about a decade but I’m starting to make stronger juices in order to gives to friends as shortfills. I use 100ml bottles and 20mg nic salt shots. I’m kinda reckless for my own needs and just chuck it in but I could do with knowing some actual figures now as my friends vape certain strengths (1.5mg or 3mg) and I don’t want to give them something too strong. It’s not important that the resulting e liquid will be slightly weaker/stronger in terms of taste, I put a decent amount of flavour in to begin with to compensate.
For the life of me, I can’t work out the resulting strength in these two scenarios:
90ml e liquid (80/20) + 1 bottle of 20mg nic salt shot (50/50)
85ml e liquid (80/20) + 1.5 bottles of 20mg nic salt shot (50/50)
80ml e liquid (80/20) + 2 bottles of 20mg nic salt shot (50/50)
I’ve tried to use online calculators but they don’t seem to cover what I’m asking. I see shop bought shortfills often come in 60ml bottles (with 50ml eliquid in them) or 120ml bottles (with 100ml e liquid in them).
I’m a bit old school and used to buy 500ml bottles of the 72mg stuff and kept in the freezer (before that tragic TPD event) so now I’m a bit clueless to be fair, spending like £1 for a 10ml bottle of useless strength nicotine.
Any help or a pointers in the right direction would be really appreciated, cheers
