ph question

[daf]

what is the difference with a ph tester and moisture meter, and what is the optimal ph :confused:

A PH meter tells you the PH of the soil or water that you are using and a moisture meter tells you how wet the soil is, so you can decide if you need to water the plant or not.

Optimum PH depends on what you are growing but if it is the obvious it should be between 6.2 and 6.8.

PH is a measure between acidic and alkaline.
