just watched this....and short of having a dripping device for testing it looks like what ive been doing is right...although i have done a complete 1 mil mix first rather than without the nic...this i shall be doing in the future
....hopefully ill be getting a nice dripping atty this week so i can carry on in my ventures
I would recommend getting a small bottle of the cheapest vodka and some Milton fluid. Any 510 or 306 atomizer will do for testing - as long as there is no fibre (silica wicks etc) in there. You will find you want to clean these out regularly.
Cleaning methods include
a) Blowing excessive juice out of the bottom of the atomizer onto tissue paper
b) (a) + dripping VG or PG into the atomizer and vapourizing this off
c) Dripping vodka into the atomizer swirling it, blowing out onto tissue paper and dry burning
d) Washing in tap water & drying
e) Soaking overnight in vodka
f) Soaking overnight in Milton solution then washing under a tap and drying
g) Soaking overnight in vodka, washing out soaking overnight in Milton and washing out (extreme).
Test atomizers get hammered - I have had two start to physically fall apart whilst still functioning perfectly - cheaper is better.
You might find that you do a lot of dry burning and have the drip tip(s) in and out of these a lot.
1ml mixes are a good idea if you have graduated 1 ml syringes and if you are not concocting and using tiny amounts of very powerful concentrates - for this 5ml samples are better.
Another thing to do with super strong concentrates, such as tobaccos is to cut them into PG before you mix them - e.g. with a tobacco, create a 10% solution first. If you add 1 ml of this 10% solution to 9ml of base, you will have created a 1% final mix. The cut solution for mixing doesn't have to be 10% - it could be 50% or 25% - anything that is weaker and which you can easilly do the sums around will give you more control.
