I just recently started vaping. I've gone through a few cart. and have quickly realized that refilling is mandatory.$$$ However, my results are unsatisfying. I saw a vid. clearly showing HOW..that's not the problem. It's what's going in the cart. First I should mention that I am in Canada and you can't buy PG here so I'm using VG.There just is NO hit and even though I lucked out finding someone close by selling LorAnn's full line, many containg PG,still very little kick and the cart. always seems to be clogged which doesn't help either. My question would be.."Is there something else that I could add to the mix that might add hit?" I am presently just at 75% VG and 15-15 DW & flavor,which is really just a basic starting point. Any input is welcome. Thanks.
