What is a growing medium ?


By definition, a growing medium is the environment where the roots of the plants cultivated in this way will grow and spread.

A substrate can be fertilized or inert, active or neutral, draining or with a high capacity of water retention, such as Sphagnum or rock wool.

Following the choice of his substrate, the cultivator will have to administer a balanced and increasing nutrition, in forms of liquids or powders, mineral and / or organic. This one will take care in this sense, to correspond to the needs of the plants and according to the various stages of culture.

In the same way, the frequency and the quantity of the contributions in water and nutrients will have to take into account the power of drainage, relative to the adopted substrate.

What are the various forms of substrates that can be found on

If you are looking for a traditional culture, gives you access to an impressive list of mixtures of ready to use soils, enriched with various types of peat, with or without perlite, with more or less pronounced drainage powers.

These potting soils are called Light Mix, Grow Mix or Royal Mix, and are also available with or without fertilizing properties (organic and/or mineral) and in various packaging.

On the other hand, if you wish to access more modern methods of cultivation , hydroponic cultivation, which is increasingly popular in the domestic setting and has long been implemented in the agri-food sector. In other words, growing on an inert, non-fertile medium requires an imperative and close monitoring of the nutrient solution to be provided continuously, through measuring instruments ofEC (electro-conductivity) and pH (hydrogen potential).

These hydroponic substrates, neutral or not very rich, can be found in the form of expanded clay balls, coconut fibers, rock wool, perlite, pozzolan, vermiculite, sphagnum moss,aquanappe (external hydrophilic coating of plant walls)...

How should we water these various substrates?


For substrates with high nutrient retention, mechanical irrigation by hand (andwatering can!) is to be considered but can be replaced by an automated fertigation, using an irrigation circuit, composed of pipes, water pumps and cyclic programmers.

Passive systems based on the principles of gravity (Blumat) and capillarity (AutoPot) are even to be recommended for this type of culture.

On the other hand, if the substrate used is hydrophilic and has little or no capacity to retain the nutrient solution, automated irrigation will necessarily be required.
