first welcome and good questions )
Do you all keep your filled carts in a zip lock bag ? Does the juice evaporate ?
no i do not keep em in a bag....yes juice can evaporate of sorts
2) Again with the evaporation ... but do you all recap (with rubber stopper) the cart after vaping, then uncap and put back on when its time for the next vape ? Or do you just leave on until its tapped out.. i reuse the plastc seal and cap on my carts when i dont use them alot... now i mostly drip right onto the atomiser and dont use carts at all...
