Grow Tent Negative Pressure High CFM Support Mounts

Stop Negative Pressure Collapse!

If you’re running a high-CFM exhaust fan in your grow tent, you’ve probably noticed the sides getting sucked in due to negative pressure. This not only reduces your available grow space but also gives the tent a warped, compressed look.

No more makeshift plastic hanger tricks or bulky solutions. This simple mount slides over your tent’s existing frame and allows you to insert a 3/4" (~19mm) dowel rod (available at hardware stores), creating a sturdy internal support structure. Just secure the dowels with a zip tie, and your tent will maintain its shape without restricting plant space!

This was designed using a Vivosun grow tent but is compatible with any tent that uses 16mm framing.*

Why Use This?

✅ Maximize Grow Space – Prevent tent walls from collapsing inward, keeping plants from getting squeezed.
✅ Clean & Professional Look – No more sucked-in sides; your grow tent looks and functions as it should.
✅ Easy to Install – Slides onto your tent frame, and securing a dowel rod takes just seconds. The mount simply rests on the framing “push button” connector.
✅ No Permanent Modifications – Works with your existing tent frame, no drilling or cutting required. 
 

Upgrade your grow tent setup today and keep your plants thriving without dealing with negative pressure collapse! 

*If you have any need for different framing sizes, comment with those dimensions and I will modify the model to accommodate that.  

**Note: these may be a little snug but should push on with a little bit of force.
