Hello, I've decided I'm gonna try my hand at homemade juice, I picked up some glycerin today, still need to track down the propylene glycol and flavouring, probably not gonna bother with nicotine at the moment, if I find I need it I will deal with that later. My question is how long do you guys like to leave your homemade juice to steep before vaping it? Do you find different flavours require different steep times?
