In this thread we will cover the level of PH in your reservoir, and in your soil.
PH for Hydroponics solutions are 5.8-6.1 (slightly acidic) This margin of error is fine and should never cause you any issues. Too high or too Low a PH level and you can lock out essential nutrients from the plant, potentially causing less yield, making plant susceptible to disease, and even death
When using "fertigation" methods, (delivering nutrient solution to a Soil bed), desired PH level is between 6.5 - 7.0 (a bit acidic to neutral).
You can test solution or soil runoff with a simjple garden test kit.
Or; It is recommended to get a PH pen or meter , a TDS/EC pen or meter, and a waterproof temp. gauge or meter.
We will be posting images of some PH, TDS, EC, and Multimeters we have used over the years. We use Milwaukee Meters at our farm.
