What is the composition and characteristics of coco coir?
Before exploring the details, it’s important to understand the
composition and characteristics of coco coir. This substrate is derived from the residue of coconutsafter processing. These recovered fibers are transformed into powder and filaments, thus providing an ideal substrate for hydroponic cultivation. This applies to
ornamental plants or intensive crops Compared to soil, coco coir offers several significant advantages for cannabis cultivation. One of its major characteristics is its inertness. Since coco coir is an inert substrate, it does not provide nutrients to the plants. Therefore, nutrients must be supplied in the form of liquid fertilizers with each watering.
How important is oxygenation in coco coir cultivation?Oxygenation is one of the most notable advantages of growing in coco coir. This growing medium is extremely well-aerated, which promotes rapid root development compared to soil. Root growth results in a shorter vegetative cycle and accelerated overall plant development. Furthermore, the natural presence of trichoderma (fungal fungi) further enhances the benefits of this substrate.
The presence of coconut fiber helps stimulate root development and strengthen the plants’ natural defenses, thus facilitating optimal metabolic processes.
How to manage watering in coco coir? Watering is one of the key elements of coco coir cultivation. As mentioned above, due to the inertia of this substrate, nutrients must be supplied with each watering. Measuring the pH and EC (Electroconductivity) of the nutrient solution is crucial for maintaining the appropriate levels. The pH should be maintained between 5.5 and 6.3, adjusting it according to the plant’s growth stage. For growth, a pH of 5.8 is ideal, while for flowering, a pH of 6.0 is recommended.
What fertilizers and additives are suitable for coco coir cultivation? Fertilizers and additives should be chosen according to the specific needs of growing in coco coir.
Chelated fertilizers are the most suitable, due to their rapid and efficient absorption by plants. It should also be noted that there are mineral and organic fertilizer options for growing in coco coir as well. How to manage containers and watering?
Containers or pots used for growing in coco coir must have a
good drainage system
to remove excess water . This ensures a moist substrate while promoting oxygenation, which is essential for optimal nutrient absorption , and to prevent any
root rot problems . How important is root cleaning? Root cleaning is very important because it removes salts generated in the substrate. It is recommended to clean the roots when the EC of the runoff is above 2.5.
