Review on 🌱 OptiGrow PH Probe by Ryan Ramirez

I bought this replacement pH probe for one of my two Premium Grobo devices. The probe is packaged very nicely and most importantly sealed in a container of storage solution! This pH sensor is an exact replacement for the pH sensors used in Grobos. The sensor cable is about 4 feet long, long enough to fit in a Grobo. Installation was simple removal and replacement of the old sensor with a new one. This product has a competitive price! About 2 months ago I bought a Blue Labs pH probe to replace in my first unit. I can say that the Grobo pH probe is cheaper and better packaged!
