Earth and Composting

Growing marijuana in soil remains a preferred option due to its simplicity, accessibility, and the superior quality it can offer in terms of flavor and aroma. Although it may present challenges such as increased pest risk and potentially lower yields compared to more advanced methods, its advantages are significant, especially for novice growers or those who prefer organic methods.

At GrowIndustry.es, we provide high quality land and all the necessary advice to maximize the potential of your crop. Not only is soil a forgiving and easy-to-manage growing medium, it also allows growers to experiment with different mixes and supplements to optimize growing conditions.

The inclusion of different types of peat and complements such as perlite, vermiculite or coco allows growers to adjust the mixture to their specific needs, improving aeration, water retention and nutrient availability. With regular monitoring and adjustments when necessary, soil can be an exceptionally effective and rewarding growing medium.

• Difficulty: Easy
• Cost: Low

Advantages :

• Accessibility : The land is easily accessible and does not require a large initial investment. You can find it in any garden or buy it in specialized stores, like ours at GrowIndustry.es, where we offer you high-quality options adapted to your needs.
• Error Tolerance : The soil is incredibly forgiving, making it the ideal choice for those who are taking their first steps into the world of cultivation. Small errors in feeding or watering will not have devastating effects, allowing progressive learning without pressure.
• Organic Farming : For purists and those looking for a more natural approach, soil is the perfect medium. It allows the use of organic fertilizers and promotes a more sustainable and environmentally friendly growing environment.
• Superior Flavor : Many growers and consumers agree that soil-grown marijuana has a richer, more complete flavor profile. The complexity of the soil and the variety of microorganisms present contribute to a more complete development of terpenes, resulting in a superior sensory experience.

Disadvantages :

• Risk of Pests and Diseases : Soil is a living environment, and as such, it can harbor pests and diseases that threaten your crops. At GrowIndustry.es, we provide you with the tools and knowledge necessary to prevent and treat these problems. Additionally, here is a guide onhow to avoid pests on marijuana plants , ensuring the quality and health of your plants.
• Minor Crops : Although soil can produce exceptional results, it is true that, in terms of quantity, it can lag behind other more advanced media. However, many growers are willing to make this sacrifice for quality and flavor.
• Slower Growth : Plants in soil may take longer to show signs of deficiencies or excesses, which could delay necessary intervention. We teach you to read your plants' signals and act in time to ensure optimal development.

Different Types of Peats on Earth

Peat is an organic component commonly found in growing soil mixes, and its inclusion can have a significant impact on the structure and properties of marijuana substrate . There are different types of peat, each with unique characteristics that can benefit marijuana cultivation in various ways.

• Blond Peat : This type of peat is characterized by its light color and its relatively low state of decomposition. It is rich in fiber and has excellent water retention capacity, which helps maintain moisture in the substrate. Blonde peat also provides good aeration, which promotes the development of a healthy root system.
• Black Peat : Unlike blonde peat, black peat has a dark color and a higher degree of decomposition. It is denser and has a greater capacity to retain nutrients, which can be beneficial for feeding plants over time. However, due to its density, it may have a lower aeration capacity compared to blonde peat.
• Sphagnum Peat : This type of peat is derived from sphagnum moss and is known for its ability to retain large amounts of water. It also has natural antiseptic properties, which can help prevent plant diseases. Sphagnum peat moss is light and airy, providing an ideal environment for root growth.

Complements to Aerate the Earth

Aerating the soil is a crucial aspect of growing marijuana, as it ensures that the roots of the plants receive the oxygen necessary for healthy growth. There are various supplements that can help improve the aeration of the substrate and, therefore, promote optimal plant development.

• Perlite : This expanded volcanic material is one of the most popular supplements to improve soil aeration. Its light and porous structure helps create spaces in the substrate, allowing air to circulate freely and reach the roots. Additionally, perlite helps improve drainage, preventing waterlogging.
• Vermiculite : Although best known for its ability to retain water, vermiculite also contributes to soil aeration. Its lamellar structure expands when heated, creating small channels that allow air to pass through.
• Coarse Sand : Incorporating coarse sand into the substrate can significantly improve aeration and drainage. It is important to ensure that the sand is clean and free of salts that can negatively affect plants.
• Coconut : Coconut fiber not only retains water well, but also provides excellent aeration. Its fibrous structure creates spaces in the soil that allow air flow, favoring root development.
• Pine Bark: This organic material can be used to improve soil aeration. Its thick and porous structure helps create spaces in the substrate, allowing air to reach the roots.

The Ideal Soil Mix for Marijuana:

• 40% Peat : You can use a combination of blonde peat and sphagnum peat to get the benefits of both. Blonde peat provides aeration and water retention, while sphagnum peat adds water holding capacity and antiseptic properties.
  • Mob Distribution:
    • 20% Blonde Peat : This peat provides excellent aeration and water retention, creating a light, fluffy environment for roots.
    • 15% Sphagnum Peat : With its high water retention capacity and antiseptic properties, sphagnum peat helps maintain humidity and protect plants from diseases.
    • 5% Black Peat (optional) : If you decide to include black peat, it can provide density and nutrient retention to the mixture. However, it is important not to overdo it with this type of peat to avoid drainage problems.

• 30% Perlite : This material will improve aeration and drainage, ensuring that plant roots receive enough oxygen and preventing waterlogging.
• 20% Vermiculite or Coconut for marijuana : Both materials help retain water and nutrients, which is crucial for plant growth. The choice between vermiculite or coconut will depend on your personal preferences and the availability of materials.
• 10% Compost or Worm Humus : This organic component adds essential nutrients to the substrate, promoting microbial activity and improving soil structure.

If you want to avoid having to make the soil mix yourself and for greater convenience you can also choose to use Janeco Light mix from Atami with which you can plant practically anything.

Additional considerations:

• pH : Make sure the pH of your soil mix is ​​in the range of 6.0 to 7.0, which is ideal for most marijuana plants.
• Nutrients : Depending on the growth stage of your plants, you may need to add marijuana-specific fertilizers that can provide the necessary nutrients.
• Testing and Adjusting : It is advisable to test pH and nutrients regularly and adjust your soil mix as necessary.
• Experimentation : Don't hesitate to experiment with small variations in proportions to find the mixture that best suits your specific conditions and the needs of your plants.

In short, the soil stands out for its ease of use, tolerance for errors and the superior quality of the final product, making it an excellent choice for growers of all levels. We are here to help you make the most of this timeless and proven growing medium, ensuring success and satisfaction in your marijuana cultivation.
