So I ordered my first supply of diy from wizard labs. Been reading a lot about it to prepare. My question is, what is better for the nicotine base, PG or VG? My mixes will be a 50/50 PG,VG. Does it matter as long as I input it correctly in the e juice calculator? Which one would be better for putting the nic in the freezer. My initial shipment will be PG nic base but for future reference, I wanted to ask. Thank you.
