For DIY or to complete your shortfill liquids, you must start by selecting your base. Thanks to neutral aroma bases, you will be able to dilute your few drops of aromas or your concentrated bottle.
Do you like to make a lot of steam ? Then, choose a base with a high rate of VG (Vegetable Glycerin) and go for 30/70. If you wish to enhance the taste, go for a 50/50 base with more PG (Propylene Glycol).
