I am going to start buying some supplies tonight. I am trying to get the most bang for my buck and had a couple of questions. Amazon has 1 quart PG and VG from Froggys for a really good price. Anyone tried these? I am planning on buying the 100mg PG Nic mix from Wizard Labs. so my next question would be on the diluting of the Nic. I assume that 50/50 unflavored base, if I use 25% NIC, 25% pure PG and 50 % pure VG I would have a base of 25mg unflavored NIC solution. Am I correct in this assumption? I value your opinions here. Any better recommendations?
