PH meters

In order for plants to thrive indoors, no matter what type of substrate is used, they must be acidic. Excessive acidification of the substrate may lead to an insufficient amount of elements necessary for the proper development of plants, and even cause their death. Even if we try to supplement the minerals with mineral fertilizers, the plants will not be absorbed by the acidified soil.

Substrates with appropriate pH

It is best to use a ready-made soil mixture with a pH suitable for the plants we cultivate or a neutral acid soil. The best way to avoid problems with the acidity of the substrate is to buy a pH-meter, so we will carefully check its pH, eg. Using the biological pH regulator Plagron Lemon kick 5 can lower its pH.
