hey all. so i got into rebuilding a few weeks ago. it proved to be extremely frustrating so I've only done a few builds but I'm still fiddling and experimenting with it. when i first bought all my supplies from my local vape shop i bought cotton from them. it was just a bag of a 4X4 chunk of cotton. since it was from a vape shop (and this is a legit vape shop with experienced builders and vapers) i assumed it was the right kind of cotton and was ready to go so i got home did my first build, pulled off some cotton and began cloud chasing. now that i think about it i hear so much about boiling cotton, do you guys think this cotton still needs to be boiled? i know this is a question better suited for the shop i got this from but i just wanted your guys opinion. and also if am supposed to boil it, any tips on how to do so? I've heard your supposed to use distilled water. where can i find that? i don't have a water filter. or does boiling the water prior to adding the cotton distill it? thanks for the help guys
