What are the advantages of outdoor cultivation

Whether it is hemp, autoflowering cannabis, or other ornamental species, planting outdoors offers several significant advantages for growers compared to indoor, greenhouse, or grow box cultivation. Among the positive aspects that make outdoor crops an appealing choice, we can include:

  • Exposure to sunlight: Natural sunlight provides a full and balanced light source that stimulates plant photosynthesis, promotes vigorous growth, and enhances the production of high-quality cannabinoids and terpenes;
  • Natural ventilation: The outdoor environment offers constant airflow, helping to reduce the risk of mold and diseases while keeping plants healthy and vibrant;
  • Lower energy costs: Outdoor growing drastically reduces energy costs associated with artificial lighting and ventilation systems used in indoor environments, such as grow boxes;
  • Reduced equipment costs: Unlike indoor cultivation, which requires specialized equipment, outdoor cultivation requires fewer tools, thereby reducing initial and maintenance costs;
  • Lower environmental impact: Outdoor cultivation is more sustainable as it requires fewer energy resources and has a smaller environmental footprint compared to indoor cultivation;
  • Natural life cycle: Outdoor plants can follow seasonal cycles, which influence their growth, fostering the development of plants better adapted to their environment;
  • Natural soil and nutrients: Plants grown outdoors can benefit from the nutrients found in natural soil, providing a complete nutrient profile without the use of chemical fertilizers.

Outdoor cultivation represents an opportunity to achieve high-quality yields sustainably, reducing costs and energy while fostering a more harmonious approach with nature.

How to cultivate outdoors: tips and key aspects to consider

If your goal is to achieve abundant outdoor cultivation, it is crucial not to overlook the key aspects of this method. As you will see, these are critical factors that can determine the success or failure of your crops.

Choosing the Right Variety:

  • Selecting the most suitable plant variety for the environment in which you plan to cultivate is essential for successful outdoor growing. Do not base your choice solely on personal preferences, but opt for plants that are well-adapted to the local climate and resistant to diseases and pests.

Proper Placement:

  • Choosing the right location for planting is fundamental. Ensure that plants have access to a nearby water source and, most importantly, receive as much direct sunlight as possible—at least 6 hours per day—while avoiding excessive exposure that could damage the leaves.

Soil Preparation:

  • A fertile, well-drained soil with the right moisture balance is crucial for healthy plant growth. Make sure the soil is free from harmful contaminants, retains water adequately, and has a pH between 6 and 7, or one suitable for the specific outdoor plant you intend to cultivate.

Sowing:

  • Every grower must carefully plan the timing of outdoor sowing, considering plant type and local climate. Adhering to the correct depth and spacing between seeds is essential for optimal growth. You might consider pre-vegetating plants indoors and then gradually exposing seedlings to direct sunlight.

Adequate Irrigation:

  • Providing plants with the right amount of water is the best strategy for achieving healthy growth. It is important to carefully regulate water supply to avoid overwatering or drought. Water retention aids can be beneficial in cases where regular irrigation is challenging.

Balanced Fertilization:

  • Balanced organic fertilizers can be used to ensure the plants' proper growth. However, fertilization must be adapted according to the different growth phases, paying close attention to prioritizing nitrogen, phosphorus, and potassium in the appropriate proportions.

Pest and Disease Control:

  • Outdoor crops expose plants to a higher risk of harmful insect attacks. This is why constant monitoring of the plants is necessary to detect any signs of diseases or pests and intervene promptly with natural and safe solutions if needed.
  • By following these guidelines, you will know how to cultivate outdoors successfully, achieving a bountiful and high-quality harvest. Keep reading to learn everything about outdoor cannabis cultivation.

Growing Cannabis Outdoors: What You Need to Know

First and foremost, outdoor cannabis cultivation is not legally permitted in many areas. However, with a careful and well-planned approach, it is possible to grow various legal hemp strains, including autoflowering and feminized varieties, achieving vigorous and high-quality plants. There are many advantages to growing cannabis outdoors.

Sunlight, fresh air, rainwater, and natural soil are free resources that make this experience rewarding and fulfilling, offering every grower the opportunity to:

  • Grow larger plants;
  • Utilize ample space for cultivation;
  • Prevent mold and diseases caused by humidity;
  • Practice companion planting with different outdoor crops;
  • Grow in naturally rich soil with beneficial indigenous microorganisms;
  • Reduce the use of chemical fertilizers.

As mentioned in the previous section, there are several factors to consider before starting outdoor cannabis cultivation.

First and foremost, it is essential to choose an appropriate location, considering temperature (between 12°C and 30°C), sunlight exposure (at least 6-8 hours per day), and protection from adverse weather conditions. Some options include growing marijuana on private balconies and gardens, guerrilla outdoor cultivation, or greenhouse setups.

Each outdoor growing area has its own advantages and disadvantages, requiring careful consideration of irrigation, plant health preservation, pest prevention, and pollination management.

The choice of genetics is also fundamental, taking into account the local climate and desired effects. Additionally, attention must be given to the plant’s early growth stage: germination requires darkness, humidity, and water, and it can be initiated directly in a pot. Once the seedling has sprouted, it should be transplanted outdoors. During the vegetative phase, plants focus on photosynthesis and leaf development.

Outdoor growing of Autoflowering and Feminized Strains

Autoflowering outdoor seeds produce plants that are genetically programmed to flower independently of light cycles.

This means that they do not rely on the length of day and night to initiate flowering, unlike photoperiod-dependent strains.

In outdoor environments, this translates into greater control over the growth cycle and the possibility of multiple harvests per year.

Autoflowering strains often have a shorter growth cycle, allowing for a rapid production of mature buds.

On the other hand, growing feminized seeds outdoors offers another interesting perspective.

Feminized strains are specially bred to produce only female flowers, which contain the highest concentration of cannabinoids. 

Growing feminized plants eliminates the need to identify and remove male plants during growth, simplifying the cultivation process and ensuring a harvest focused on resinous buds.

However, cultivating feminized seeds outdoors requires a good understanding of the plant’s growth cycle and specific needs at each stage.
