Here’s the best advice. If it’s not cannabis. Or imitating IE: non cannabis derived terps. You shouldn’t be vaporizing it with your cannabis. The only reason you are defending putting pg, vg, whateverpoisonyoupeddleG, mct. Is because you aren’t making them correctly. As far as getting undercut because you are buying your disty. A turnkey kit can cost you less than 12k. You may be able to turn competitive after that. Don’t put cooking oil in your vape carts. Unless you eat paint chips and lived by power lines as a kid.
