How often do you calibrate your pen?

i should be calibrating them atleast every other day but i dont. and it makes a dif.By you post i am assuming you will be using soil first. As soon as you start hydro I would def get a ph meter. it is soo important you kep the ph constant and dont let it go to high or to low. I have seen nute solution shoot up to 7.5 when the air stone is added. you are gonna have to dip those strips over and over and over to make things right.
