Description
This video will show you how to check or change the pH of your water before using it to water your plants. For soil an optimum pH is between 6.0 and 7.0, or about a 6.5 For hydroponics an optimum pH is between 5.5 and 5.9 Attention!! a small change in pH ,even with 0.3, can cause disease for your plant because pH is a logarithmic scale. the an pH about 5.0 will be 10 times acidic than pH about 6.0, and 100 times more acidic than neutral pH (7.0). So you will adjust pH depending on growth period.
