growing hydro with no way of checking ph

[fhydro]

Hey latewood, you've got the milwaukee, so have i. Where do you make the PH pen stay when you don't use it? Now i let it bathing in a glass of water, because before ( i used to close it ) i had some algae growing on the electrode and it indicated PH 6 even when it was 4. Now i've got some hermies, bullshit! Do you calibrate it often ?
