Types of fertilisers for marijuana

Growing cannabis requires not only dedication and patience, but also providing the right nutrition for the plants. Fertilisers play an essential role in the development of plants, providing them with the nutrients they need at every stage of their growth. In this guide, we will explore the types of fertilisers available, their characteristics and how to choose the right one for your needs and type of grow.

Classification of fertilisers by origin

Fertilisers can be classified according to their origin into three main types: minerals, organic y organic-minerals. Each type has its particularities, advantages and disadvantages, which are detailed below.

Mineral fertilisers

Mineral fertilisers are produced by chemical processes, in which substances and elements are mixed to provide an optimal combination of nutrients. This type of fertiliser allows precise control over the amount and ratio of nutrients, ideal for growers looking to maximise yields, especially in indoor crops.

Advantages of mineral fertilisers:

• They allow precise control of nutrients.
• If properly applied, they leave no residues and have minimal environmental impact.
• They are ideal for automated irrigation systems and indoor crops.

Organic fertilisers

Organic fertilisers come from natural sources, such as humus, peat and various types of compost. They provide biological nutrients in their natural form, without chemical processes, allowing the plant to receive nutrients gradually, which is beneficial for the soil and the overall health of the plants.

Disadvantages of organic fertilisers:

• Its nutrient concentration is lower compared to mineral fertilisers, which requires more frequent applications.
• Some components, such as meat and bone meal, may present risks if they do not come from reliable sources.

Organic-mineral fertilisers

These fertilisers combine the benefits of minerals and organics, offering balanced nutrition that respects the environment. They may include components such as humus for nitrogen or potassium oxide for potassium, which helps to maintain balanced nutrition.

Classification of fertilisers by physical state

In addition to their origin, fertilisers can also be classified according to their physical state: liquids y solids. The choice between one or the other will depend on the cultivation system, the type of application preferred and the specific needs of the plants.

Liquid fertilisers

Liquid fertilisers are popular, especially in indoor cultivation. They are easy to use and allow a customised nutrient mix. Their format facilitates application through automatic irrigation systems and they are ideal for hydroponic and aeroponic crops. In addition, the nutrients are absorbed quickly, allowing for an immediate response from the plants.

Solid fertilisers

Solid fertilisers, such as granular or powdered fertilisers, are applied by mixing them into the substrate or directly onto the soil. They are released slowly, providing prolonged nutrition, ideal for those who are looking for a gradual feeding of their plants.

Advantages of solid fertilisers:

• Its durability is longer, with applications lasting several weeks.
• They are a more economical option in the long term compared to liquids.

Other common supplements in cannabis cultivation

In addition to traditional fertilisers, there are other supplements that help to improve the health and yield of cannabis plants, such as:

• EnzymesThey help to break down organic matter in the soil, improving nutrient absorption.
• Mycorrhizae and TrichodermasBeneficial fungi that improve nutrient absorption and protect against pathogens.
• Vitamins and Amino AcidsStimulates growth and strengthens the immune system of plants.

Conclusion: What is the best fertiliser for you?

Choosing the right fertiliser will depend on your preferences, crop type and specific objectives. If you are looking for precise control and fast growth, mineral or liquid fertilisers may be ideal. If you prefer a more sustainable and environmentally friendly option, organic or solid fertilisers may be the best choice.

Remember that, as with all aspects of growing cannabis, balance is key. Providing your plants with a balanced diet in the right doses is essential for the best results. Over time, you will be able to experiment and adapt your methods to maximise your plants' potential - good luck and enjoy the process!
