New Grower Ph probe storage solution

[DazedAndStoned]

I calibrate ever single month on the first of each month. Usually it's within point 1 but sometimes if salt is built up on it it may be off a bit more. If you got the blue labs kit it should have came with a bit of cleaning paste and a brush. I clean it and then calibrate once a month or if I notice a reading on my dwc girls is off.

Just in plain tap water?

Yeh plain tap water....when I do calibrate it's only off by a point or two..

I always rinse/clean mine with Distilled water as there is no salts or chlorine to mess with the probe
