Outdoor Scrogging cannabis guide

In the world of cannabis cultivation, outdoor scrogging has emerged as a popular method for maximizing yield and quality. This technique, also known as Screen of Green (Scrog), involves training plants to grow horizontally under a screen, allowing for optimal light penetration and improved airflow.

In this comprehensive guide, we will explore the concept of outdoor scrogging and its benefits, provide step-by-step instructions on setting up your scrogging system, offer maintenance tips, and discuss expected yields and considerations.

Let’s dive in!

Understanding Scrogging: What is it and its Benefits

Scrogging refers to training cannabis plants to grow horizontally beneath a screen. This technique aims to create an even canopy, maximize light distribution, and encourage bud development. By gently manipulating the plants’ growth patterns, growers can optimize their outdoor cultivation.

Key Benefits of Outdoor Scrogging

Light Optimization

One of the primary benefits of outdoor scrogging is the optimization of natural sunlight. By spreading the branches horizontally under the screen, scrogging minimizes shading and ensures that all parts of the plant receive adequate light. This results in improved photosynthesis, stronger bud development, and ultimately, higher yields of top-quality cannabis.

Improved Air Circulation

Scrogging also promotes better airflow within the canopy, reducing the risk of pests and diseases. Proper ventilation prevents the formation of mold and mildew, which can significantly impact the health and yield of cannabis plants. With outdoor scrogging, growers can create a well-ventilated environment that keeps their crops healthy and thriving.

Increased Bud Development

By training the plants to grow horizontally and optimizing light penetration, scrogging encourages the plants to focus their energy on bud production. With a balanced canopy, each bud site receives sufficient light, resulting in bigger, denser, and more potent buds. Growers can expect enhanced yields and improved overall bud quality.

Enhanced Control

Outdoor scrogging offers growers better control over plant height and growth patterns. By manipulating the plants’ growth through gentle training techniques, growers can achieve a more uniform canopy, manage plant stress, and optimize overall plant health. This level of control allows for a more efficient and productive cultivation process.

Reduced Visibility

For those growing cannabis in regions where legality or privacy is a concern, outdoor scrogging provides an added advantage. The dense foliage and horizontal growth under the screen help conceal the cannabis crops from prying eyes. This increased privacy can contribute to legal compliance and enhance overall security.

How to Set Up Your Outdoor Scrogging System

To implement outdoor scrogging successfully, you’ll need to set up a proper scrogging system. Let’s explore the equipment recommendations and the process involved:

Equipment Recommendations

To begin your outdoor scrogging journey, ensure you have the following essential equipment:

  • Sturdy Frame or Supports: Choose a robust structure to hold the screen and support the weight of the plants. Materials like bamboo, PVC, or metal poles work well for this purpose. Construct a sturdy frame that can withstand outdoor conditions and securely hold the screen in place.
  • Strong Netting or Trellis: Select a durable screen or netting material that can support the weight of the branches and buds. Opt for a mesh size that allows easy access and maneuvering for maintenance tasks such as pruning, watering, and harvesting.
  • Plant Ties and Clips: Use soft plant ties or clips to secure the branches to the screen. Gentle training and support will help avoid damage to the plants while ensuring they grow horizontally and remain in place.

Setting Up Your Scrogging System

Once you have the necessary equipment, follow these steps to set up your outdoor scrogging system:

Determining Plant Spacing

To achieve an optimal canopy, calculate the appropriate spacing based on your desired canopy size and the specific strain you’re growing. Balancing plant density and airflow is crucial. Consider the mature size of the plants and allocate adequate space between them to promote healthy growth.

Installing the Frame and Screen

Assemble the sturdy frame or supports in your outdoor growing area. Ensure it is firmly secured to the ground to withstand wind and weather conditions. Attach the strong netting or trellis to the frame, ensuring it is taut and properly positioned to support the plants as they grow.

Transplanting and Training

Transplant your seedlings or young plants into the scrog system once they have established a healthy root system. Gently guide the branches through the screen, training them to grow horizontally. Secure the branches to the screen using the recommended plant ties or clips, allowing for some flexibility as the plants mature.

Maintaining an Outdoor Scrogging System

Once your outdoor scrogging system is set up, it’s essential to maintain it properly to ensure optimal growth and yield. Here are some tips and tricks to help you along the way:

Pruning and Defoliation

Regular pruning and defoliation are key components of outdoor scrogging. By removing excess foliage, you promote better light penetration throughout the canopy, which results in improved bud development. Trim away any large fan leaves that block light from reaching lower bud sites. Additionally, prune away any diseased or damaged leaves to maintain plant health.

Watering and Nutrient Management

Proper watering and nutrient management are vital for the success of your outdoor scrogging system. Given the dense canopy, it’s important to monitor moisture levels closely. Water your plants evenly, ensuring the entire root system receives sufficient hydration. Be cautious not to overwater, as excess moisture can lead to root rot and other issues.

Regularly monitor nutrient levels in the soil or growth medium and adjust feeding schedules accordingly. Each stage of growth may require different nutrient ratios, so be attentive to the specific needs of your plants. Consider using organic fertilizers to promote healthy growth and enhance the flavor and aroma profiles of your cannabis.

Pest and Disease Prevention

Maintaining a healthy and pest-free scrog system is crucial. Implement preventive measures such as regular inspections and the use of organic pest control methods. Keep an eye out for common pests like aphids, spider mites, and caterpillars, and take immediate action if any infestations occur.

To prevent diseases, ensure proper airflow within the canopy and avoid excessive humidity. Prune away any affected leaves or branches promptly, and consider using beneficial insects or organic fungicides as preventive measures. A proactive approach to pest and disease prevention will help safeguard your outdoor scrogging system.

Training and Support

As your plants continue to grow through the screen, ongoing training and support are necessary to maintain an even canopy. Utilize techniques such as lollipopping (removing lower branches and foliage) and supercropping (bending or manipulating stems) to manage plant height and promote an even distribution of growth.

Regularly inspect the plants and adjust their positioning as needed. Keep an eye on any branches that grow above the screen and gently bend them back down to maintain the desired canopy height. By providing consistent training and support, you’ll ensure that your plants thrive within the scrog system.

Expected Yields and Outdoor Scrog Considerations

Several factors can influence the yields you can expect from your outdoor scrogging system. Strain selection, climate, growing conditions, and the overall care and maintenance of your plants all play a role. While it’s challenging to provide precise yield estimations, outdoor scrogging has the potential to increase your overall harvest compared to traditional cultivation methods significantly.

The yield range can vary widely, depending on the specific factors mentioned above. However, it’s not uncommon for experienced growers to achieve yields of 1-2 pounds or more per plant when implementing outdoor scrogging techniques effectively. Remember that experimentation and experience will contribute to optimizing your yields over time.

When considering outdoor scrogging, take into account your specific climate and growing season. Ensure that your strains are suitable for outdoor cultivation and select those that perform well in your region. Additionally, monitor weather patterns, protect your plants from extreme conditions, and adapt your care routine accordingly to maximize their potential.


Outdoor scrogging presents cannabis growers with an effective technique for maximizing yields and quality. By training plants to grow horizontally under a screen, cultivators can optimize light distribution, improve airflow, and enhance overall control over plant growth.

With proper setup, maintenance, and care, outdoor scrogging can lead to impressive harvests of top-quality cannabis. Remember to stay up-to-date with resources as you embark on your outdoor scrogging journey.
