Vibration speeds the steeping process.
Some use a ultrasonic cleaner.
My ry4 turns gold brown in 2 weeks keeping it in the big truck with the diesel shaking it 24/7.
I mix small batches 3-5 ml. 50/50 pg vg no nic. If it tastes bad not much $ down the drain. The good ones go 30-100 ml bottles.
On fruit flavors I'm getting better results from lorann than tfa, for my tastes.
Using walmart vg and wizzard pg and nic base.
