I usually keep the meter with the cap on it and I put a small amount of the storage solution in the cap so the probe doesn't dry out. But I'm worried the mildew will contaminate the plants' water. Anybody with any advice is well appreciated, thanks. :jointsmile:
i know bleach / water solution will kill mold, just a tiny bit of bleach like a tsp to 1 cup water, it will kill mold but im not sure if it will harm your ph pen, i wouldnt think it would but look at your manufacture instructions should have directions on how to clean. But bleach will kill the mold...good luck
