Hey guys,can someone please help me? I'm fairly new into Diy and was just wondering if plastic bottles from westpack could be the reason why my flavours are abit weak? Some flavours are up to 15% but when I vape it,I 1st taste vg/pg before I get the flavour,as when I buy a flavour off the shelf I get full flavour immediately. I usually steep for atleast 1 week and even after a few weeks same thing,can it be because I'm storing in a 100ml plastic bottle? Any advice please,much appreciated
