Yep at 6 gallons of VG and pg and a liter of nic I figure in having at least 3-4 years of juice and if I buy another gly cube I should be set for 7-8 years all I'll need is flavorings and if they make some kind of restrictions on them then unflavored is still available to me! That's why DIY is perfect to start especially now before the government regulates anything
