✨ Why choose organic fertilizers for growing marijuana?
The organic fertilizers are those obtained from raw materials of vegetable or animal origin, such as manure, compost, bones or algae, among others. Unlike mineral fertilizers, which contain nutrients in synthetic form, organic fertilizers provide a large amount of macronutrients, micronutrients and enzymes that are essential for the growth of marijuana. In addition, being of natural origin, they are less harmful to the ground and to the health of the people who work in the crop and consume the final product.
The organic fertilizers are an excellent choice for those marijuana growers who are looking to obtain a quality harvest, with an exceptional aroma and flavor. Compared to chemical fertilizers, organic fertilizers provide nutrients in a natural and balanced way, which translates into a better flavor and aroma in cannabis. Also, the resulting smoke from plants grown with organic fertilizers is cleaner and smoother, without causing throat irritation. The use of organic fertilizers also allows cannabis to develop a greater intensity and variety of nuances in its flavor, which improves the user’s experience.
⭐ Types of organic fertilizers for marijuana
There are different types of organic fertilizers for marijuana, but the most common are liquids and those in dry powder form. Both have their advantages and disadvantages, and the choice will depend on the specific needs of each plant and the cultivation method used.
Organic dry powder fertilizers for marijuana plants
The organic fertilizers in dry powder are more economical and durable than the liquid ones, but they require more preparation prior to their application. It is necessary to mix them with the substrate in which the marijuana is going to be grown so that it dissolves and can release the nutrients little by little through watering, in a process known as leaching. With solid fertilizers in powder can also be made tea by mixing with water, in this way dry organic fertilizers can be used as a liquid fertilizer. This type of fertilizers are ideal for long term crops, where in addition to mixing with the substrate, a layer is usually added on top as a mulch on the surface.

🚀 Advantages of growing marijuana with organic fertilizers

This is because organic nutrients are released more slowly and in a more balanced way, allowing the plant to develop its flavor and aroma in a more natural way.
- Healthier nutrients: Organic fertilizers are made from natural sources, such as manure, compost and other organic waste. These nutrients are healthier and less toxic than chemical fertilizers, which can result in a healthier plant and safer, cleaner buds to consume.
- Better for the environment: Organic fertilizers are more environmentally friendly than chemical fertilizers. They do not contain toxic chemicals that can contaminate soil and groundwater. In addition, by using natural sources of nutrients, the amount of waste produced is reduced.
- Efective Cost: Organic fertilizers can be more expensive than chemical fertilizers in the short term, but in the long term, they can result in a reduction of total costs, especially considering that the substrate can be reused several times when grown with organic fertilizers.
✅ How to use organic fertilizers in marijuana cultivation
Before using any fertilizer, it is important to read the manufacturer’s instructions and follow the dosage recommendations. In general, organic fertilizers should be applied in small amounts and gradually, to avoid saturating the plant and causing overfertilization problems. It is also important to adjust the dose according to the variety of marijuana and the environmental conditions in which it is grown, keeping in mind that the cultivation tables provided by the manufacturers are created as a reference, and each plant may need a specific nutrition. For this reason it is recommended to start with the lowest recommended dose and adjust depending on the health of the plants.
- Calculate the total liters of nutrient solution needed for watering
- Calculate the dose of fertilizer according to the amount of total liters, if the dose is 2 ml/l and you need 10 liters of nutrient solution, you will have to mix 20 ml of fertilizer with the water
- Mix well the water with the fertilizer so that it is diluted as much as possible
- Once mixed, you can adjust the PH depending on the stage and type of crop
- If necessary, adjust the temperature of the nutrient solution so that it is between 20 and 24º C.
- Watering little by little with this nutrient solution to the plants in order not to compact too much the substrate.

👾 Frequently Asked Questions
What is the best organic fertilizer for marijuana plants?
This question is too subjective to give an objective answer, but I will tell you that any of the brands we have seen in this article will give you good results as long as you use the products well. I am going to give you a tip that many people do not take into account, and although I have put it before I will remind you here, and that is not to mix fertilizers of different brands to avoid creating nutrient blockages, since each brand makes its own formulations and makes a different distribution of nutrients.
What are the disadvantages of compost?
As they cannot be all advantages, fertilizers of organic origin also have their disadvantages with respect to mineral fertilizers, such as their higher cost, their slower assimilation, or the fact that the liquid is much denser and darker and this can be worse both for dosing and for keeping the crop clean, because it is easy to spill part of the product while it is being used.
