For the proper development of plants in indoor crops, regardless of the type of substrate used, it is necessary to maintain its appropriate acidity. Too high acidity of the substrate may lead to deficiencies of elements necessary for the proper development of plants and even for their dying out. Even if we try to replenish the minerals with mineral fertilizers, the plant will not absorb them in acidified soil anyway.
Earth mixtures with an appropriate pH
It is good to use ready-made soil mixtures with a pH appropriate for the plants we grow, or inert substrates. The best method to avoid problems related to the acidity of the substrate is the purchase of a pH meter, through which we will examine exactly its pH level, which, for example, we will be able to lower the Plagron lemon kick biological pH regulator.
