Ducting & Accessories

What Is Grow Room Ducting?

Ducting is used to transport air between different parts of your indoor growing setup. It connects extractor fans, carbon filters and outlets, allowing stale air to be removed and fresh air to be circulated efficiently.

In grow tents and indoor grow rooms, ducting plays a key role in maintaining airflow, temperature and humidity levels.

Types of Ducting and Accessories

There are several types of ducting and accessories used in indoor growing systems:

• Flexible ducting – lightweight and easy to install, ideal for most grow tents
• Acoustic ducting – reduces noise from airflow and fans
• Lightproof ducting – prevents light leaks in controlled environments
• Connectors and couplers – join sections of ducting together
• Clamps and fasteners – secure ducting to fans and filters
• Y-pieces and T-connectors – split or redirect airflow

Using the right combination of ducting and accessories ensures your ventilation system is both efficient and secure.

Why Ducting Is Important

Ducting is a key part of any ventilation system and directly affects how well air moves through your grow space.

• Ensures efficient airflow between components
• Helps regulate temperature and humidity
• Supports effective odour control when used with carbon filters
• Reduces air leaks and improves system performance

Poor ducting setup can reduce airflow efficiency, making your entire ventilation system less effective.

Choosing the Right Ducting

When selecting ducting, consider the following:

• The diameter of your fan and filter (e.g. 4″, 5″, 6″, 8″)
• The length of ducting required
• Whether noise reduction is important (acoustic ducting)
• The layout of your grow space

Matching ducting size to your fan ensures optimal airflow and prevents restrictions in your system.

Ducting in Grow Tent Setups

In grow tents, ducting is used to direct air from your extractor fan and carbon filter to an external outlet. This helps remove heat, humidity and odours while maintaining a controlled environment.

For best results, combine ducting with:

• Extractor fans and filters
• Air circulation fans
• Grow room tools to monitor conditions

This setup ensures consistent airflow and stable growing conditions.

Tips for Installing Ducting

Proper installation is key to getting the best performance from your ventilation system:

• Keep ducting runs as short and straight as possible
• Avoid sharp bends that restrict airflow
• Use clamps to secure connections and prevent leaks
• Ensure all components are tightly fitted

A well-installed ducting system improves airflow efficiency and overall grow room performance.

FAQs

What size ducting do I need?

Ducting should match the size of your fan and filter to ensure proper airflow and system efficiency.

What is acoustic ducting?

Acoustic ducting is designed to reduce noise from airflow and fans, making it ideal for quieter grow setups.

Can I bend ducting around corners?

Yes, but sharp bends should be avoided as they can restrict airflow and reduce efficiency.

Do I need clamps for ducting?

Yes, clamps help secure ducting to fans and filters, preventing air leaks and improving performance.
