Dan,
Just a quick math confimation.
In your original use with the premixed you used 1ml flavoring in a total of 10ml total
eliquid. Or 10% flavoring.
With the concentrate you are now using 10drops per 10ml? 10drops =1/2ml . That would be 1/2ml of 75% stronger flavoring or 50% stronger with out diluting the total 10ml any greater.
According to Seedmans site the concentrate to be used is mixed 1/2oz to 1 1/2oz water.
A 75% reduction in strength. Big difference if I read your math correctly.
If anyone does have the premixed, it can be made into concentrate by reducing its volume in a bowl, in a toster oven, set at abt 180*. Not to exceed 200* till the starting volume of say 1 oz is now reduced to 1/4oz. You willl now have the concentrate without
a repurchase.
