One of the most important aspects of indoor and outdoor growing is the use of a good substrate. There are many types of media in which to grow plants, and the soil substrate is the most common. The quality of the substrate will make the difference between a mediocre crop and a premium one, so it is essential to know its characteristics.Read more
Characteristics of a soil substrate
Soil substrate is one of the most widely used mediums in horticulture, due to its ease of use and excellent price. It is the most traditional type of substrate and is used to grow a wide variety of plant species, which is why it is understandable that it has been so widespread since the beginnings of horticulture.
A good soil substrate has to be made from the best raw materials and have a proportionate mix of ingredients. Traditionally, many growers have mixed the soil substrate to suit the required conditions, and this is still done in many cases.
Nowadays, however, there are soil substrate formulas that have the optimal combination of ingredients for healthy and vigorous plant growth. Thus, in addition to natural soil, a good soil substrate can also contain other elements such as a nutrient base for plants.
There are substrates that also use other elements such as dolomite, bat guano, earthworm humus, coconut fibre, etc. to promote oxygenation of the roots and nutrient supply. These elements improve root respiration and provide the plants with an extra dose of nutrients for proper growth.
Drainage is another of the key points of a good substrate. Many soils contain perlite, a kind of volcanic sand that improves the oxygenation of the substrate, making it more spongy and allowing excess irrigation to drain through the holes in the pot.
This does not imply that all soil substrates contain these ingredients. In fact, it is common to find natural, harmless, non-nutrient laden soil substrates, perfect for the grower to establish the right nutrient pattern for the growing needs. Because not all plants are the same, not all plants need the same type of substrate.
Many substrates also use pH regulators to control the acidity of the soil and adapt it to indoor and outdoor plant cultivation.

First, it is worth mentioning the Canna Terra Professional soil substrate, one of the bestsellers among European growers.
