The Secret to Bigger Yields: How Trellis Netting Improves Canopy Control

Trellis netting is one of the most effective techniques for maximizing cannabis yields. Whether you're growing in a small indoor tent or managing a large-scale commercial grow, proper canopy control ensures that every bud site gets optimal light and airflow.

This guide will break down why trellis netting is essential for canopy management, how to set it up, and how it directly boosts yield, quality, and efficiency.

1. What Is Canopy Control & Why Does It Matter?

In cannabis cultivation, canopy control refers to managing plant structure to ensure even light distribution, maximum bud production, and efficient space usage.

Without canopy control:
🚫 Some branches get too much light while others are shaded.
🚫 Buds grow unevenly, leading to popcorn buds instead of dense, uniform colas.
🚫 Poor airflow increases risk of mold and pests.

With proper canopy control using trellis netting, you can:
✔ Create an even canopy where all buds receive equal light exposure.
✔ Train plants to grow outward rather than too tall.
✔ Increase yields by maximizing productive bud sites.
✔ Improve airflow to reduce mold, mildew, and disease risks.

Trellis netting is the best tool for achieving consistent, high-quality harvests.

2. How Trellis Netting Works to Improve Yields

Trellis netting is used to train plant growth horizontally, spreading out the canopy for better light exposure and airflow. This method supports branches and prevents breakage, especially in strains that develop heavy buds.

🌱 Key Benefits of Trellis Netting for Canopy Control

✔ Maximizes Light Exposure – Ensures all bud sites receive direct light.
✔ Prevents Tall, Leggy Plants – Controls stretching, encouraging horizontal growth.
✔ Increases Yield Density – More light exposure = larger, denser buds.
✔ Reduces Risk of Mold & Pests – Improved air circulation keeps plants healthy.
✔ Supports Heavy Buds – Prevents branches from snapping under bud weight.

Using trellis netting properly leads to higher yields with superior bud quality.

3. Best Trellis Techniques for Canopy Management

There are two main ways to use trellis netting to control canopy growth:

🌱 Low-Stress Training (LST) with Trellis Netting

✅ Used in home grows & commercial setups
✅ Focuses on gradual bending and tucking of branches under the net
✅ Encourages even canopy growth and increases bud production

🌱 SCROG (Screen of Green) Method

✅ Ideal for indoor & greenhouse grows
✅ Plants are trained horizontally along a net, maximizing light exposure
✅ Reduces vertical height, making it perfect for limited grow spaces

Both techniques help manage canopy growth by keeping plants structured for better efficiency and bigger yields.

4. How to Set Up Trellis Netting for Maximum Canopy Control

🌱 Step 1: Install the Trellis Before Flowering

• Set up netting about 12 inches above plants in the vegetative stage.

• Keep it tight and level for even support.

🌱 Step 2: Weave Branches Through the Netting

• As plants grow, gently tuck branches under the netting.

• Spread branches outward to create an even canopy.

🌱 Step 3: Add a Second Layer of Trellis Netting (For Heavy Strains)

• Install a second layer 8-12 inches above the first during flower.

• This supports large buds and prevents branch breakage.

🌱 Step 4: Regularly Maintain Canopy Structure

• Trim lower leaves to improve airflow.

• Continue tucking and training until plants stop stretching.

By following these steps, trellis netting will increase efficiency and maximize yield.

5. Trellis Netting in Large-Scale Commercial Grows

For commercial cultivators, trellis netting is essential for canopy control in large grow rooms and greenhouses.

🏢 Multi-Tier Trellising for High-Yield Setups

✔ First layer (vegetative stage): Spreads plant branches for even canopy growth.
✔ Second layer (flowering stage): Supports bud weight & prevents breakage.
✔ Third layer (optional, for heavy strains): Maximizes light efficiency & stability.

🏢 Vertical Trellising for Large Commercial Grows

✔ Ideal for high-density growing with multiple harvest cycles.
✔ Supports plants growing upward, making better use of vertical space.
✔ Reduces labor costs by making canopy management more efficient.

Commercial growers use heavy-duty plastic or metal netting for durability and reusability.

6. Choosing the Right Trellis Netting for Your Grow

Soft Trellis Netting (Elastic or Nylon)

• Best for: Indoor & greenhouse grows

• Used for: LST, ScrOG, canopy training

• Pros: Flexible, reusable, and easy to adjust

• Cons: Less durable for heavy plants

Rigid Trellis Netting (Plastic or Metal)

• Best for: Outdoor & large-scale commercial grows

• Used for: Heavy bud support, vertical growth, multiple harvest cycles

• Pros: Strong, long-lasting, withstands elements

• Cons: Harder to adjust or remove

Selecting the right trellis netting ensures strong plant support and efficient canopy control.

7. Avoiding Common Trellis Mistakes

🚫 Trellising Too Late – Always install trellis netting before plants stretch.
🚫 Tying Plants Too Tightly – Allow some movement for better airflow.
🚫 Overcrowding the Canopy – Regularly prune & train plants to avoid mold.
🚫 Using the Wrong Netting – Match net strength to plant size & grow space.

Avoiding these mistakes helps ensure successful canopy control and maximum yields.

8. Where to Buy High-Quality Trellis Netting

A good trellis net should be:
✔ Strong & Durable – Can handle heavy buds & multiple harvest cycles.
✔ Easy to Install & Adjust – Flexible enough for plant training.
✔ Mildew & Moisture Resistant – Prevents mold in humid environments.
