VIVOSUN Grow Tent High CFM Kit — Adjustable Mounting Bars (39–60 in) | Heavy-Duty Support

Overview

Elevate your indoor grow setup with the VIVOSUN Grow Tent High CFM Kit. Four extendable mounting bars adjust from 39 inches to 60 inches, letting you tailor airflow layouts to your tent and ventilation system. Built for resilience, this kit uses reinforced metal bars and secure hooks that stay put under active airflow, helping you maintain a stable frame as you dial in higher CFM setups.

Flexible setup for a range of tent sizes

The design is compatible with a wide spectrum of popular tent dimensions, including 3.3’×3.3’, 4’×2’, 4’×4’, and 5’×5’ models. The extendable bars enable precise positioning to fit different widths and configurations, so you can optimize where your intake and exhaust hardware sit relative to the tent corners.

• Adjustable length from 39" to 60" for versatile installations
• Works with common 16–19 mm grow tent poles (not 22 mm)
• Arched hooks follow the tent frame to help maintain tension

Built to last in active grow spaces

Expect a sturdy, long-lasting setup. The kit uses heavy-duty metal construction that resists bending or warping, even with frequent adjustments and higher airflow. The included lightweight PP hooks are strong and secure, designed to lock onto poles with a tight fit, contributing to a stable, reliable layout over time.

• Reinforced bars provide reliable support
• Secure, self-locking connections reduce movement during operation

Smart design features that simplify installation

The arched design mirrors the natural shape of most grow tent frames, helping to distribute tension and prevent inward sag under negative pressure. An anti-rotation locking system keeps bars from twisting or slipping once you lock them in place, so you can set up and reconfigure with confidence.

• Arched hooks align with tent frames for even support
• Anti-rotation locks maintain a stable layout

Real-world use scenarios

Whether you’re configuring a single high-velocity intake or a multi-point exhaust, these poles offer the flexibility to position your equipment where it matters most. The kit’s design supports a broad range of ventilation layouts without requiring tent modification, making it easier to experiment with airflow while keeping the frame orderly.

Note: This kit is not compatible with 22 mm poles, so please verify your tent pole size before installation. The goal is a secure, adaptable setup that can grow with your space and airflow needs.
