Definizioni Importanti per la coltivazione -

Important definitions for cultivation

Growing plants, like any other hobby, has a

very specific terminology. When we start talking about methods of

cultivation, soil, pots, different types of nutrients, you are bombarded with a sea of ​​new terms. What is a substrate? Because it has value

EC and what do these numbers mean to you?

Below are the most important definitions:


This is the soil in which the plant grows. This may be substrate a

base of soil or peat, but there are also alternative bases, including coconut fiber or expanded clay. Beginner growers generally use preferred potting soil substrates. This way you don't need to use nutrients in the first few weeks to have a good structure.


This abbreviation stands for the names of the following elements:

nitrogen (N), phosphorus (P) and phosphorus (K).

Plants need these elements to grow and flower, but they require them in different quantities and combinations during the course of their life

life. For this reason, the NPK value is always indicated on fertilizer products. By doing so, the grower will have a clearer picture of the nutrient combination. Extra phosphorus and potassium are always important during flowering.

EC value.

The acronym “EC” stands for electroconductivity. Water conducts electricity more effectively if there is a high amount of salts inside it. These salts, also known as electrolytes, are included in the basic nutrition of the plant. Accordingly, the EC value also expresses the nutrient concentration in the nutrient solution. The EC value is expressed in micro/ milli-siemens per centimeter. You can measure the value in water with a conductivity meter, but it will be more difficult to do so in soil; since this retains some of the nutrients, a sample would need to be extracted. Additional information about this method will be provided later . Each culture style has recommended EC values. You can find these values ​​in the Grow Schedules.

pH value.

The pH value is used to express the acidity of the soil or water. Yes

This is a value to always take into consideration, because each species of plant has a minimum and maximum acidity limit. The soil can be acidic, pH neutral or calcareous. The acidity of the soil is determined by the presence of limestone in the soil. Sandy or peaty soils are usually more acidic than clay, because they contain less limestone. The pH value is expressed on an ascending scale, ranging from pH 1 to pH 14. PH 1 is extremely acidic pH 7

it is completely neutral. Too low a pH value blocks absorption

of plant nutrients. Each element is optimally absorbed within a certain range of pH values. Outside of this range, these nutrients will be absorbed to a lesser extent or not at all.

Growth phase.

After the seedling period, this is the first phase of your plant's life.

If you grow indoors and ensure enough (artificial) light and good nutrition, the growth phase will only last a few weeks. If you grow outdoors, this phase will last longer. During the growth phase, the plant branches at the root level and produces most of its green parts.

Flowering phase

As the days shorten and the hours of sunshine decrease, the plants

they will begin to flower and produce fruit. Essentially, it's a breeding mechanic. The shortening of the days indicates the arrival of winter, the perfect period to produce flowers and fruit so as to be able to generate new plants. For the farmer, the long-awaited moment arrives: the harvest.

In Italy the cultivation of cannabis seeds is prohibited (Art. 28 and 73 of Presidential Decree 309/90) if you do not have a specific authorization (Art. 17 Presidential Decree 309/90)

Therefore, cannabis seeds may be used exclusively for collecting purposes and for genetic preservation and are marketed with the reservation that they are not used by third parties in conflict with the law. Cannabis seeds are excluded from Presidential Decree 309/90, which means that they are not to be considered narcotic substances (L. 412 of 1974, Art. 1, Paragraph 1, Letter B; New York single convention on narcotics of 1961 and table 1 Ministry of Health decree 11 April 2006).
