Mixing Nutes

by Scientific on 12-08-2017 at 09:30 PM
My first job out of college was mixing hundreds of gallons of nutrient solutions every week at a bioengineering facility, so I've got some experience and offer you these pearls of wisdom from a former professional nute mixer.

#1 pH Measurement Mistake: Storing the Probe Tip Dry

by Scientific on 11-10-2017 at 08:29 AM
#1 on Hanna Instruments' list of no-nos is storing the glass measurement electrode at the tip of the meter dry. (You should store the electrode immersed in storage solution, or at least pH 7.0 calibration solution (which is what they do in most labs).

Storing the electrode dry can cause a coating to develop on the electrode that makes your meter slow to respond and unstable.

(You shouldn't store the probe tip in water either. Most labs store it in pH 7.0 calibration
