Modular Wall Duct for Grow Tents

With this modular wall duct, you can neatly, flexibly, and professionally guide supply and exhaust air through the tent wall of your grow tent.

The system is based on a standardized 125 mm opening, which is cut into the tent wall once. The base plate is then securely screwed in place and forms the stable foundation for all extensions.

What makes it special:
All adapters and modules are magnetically attached – completely tool-free and changeable in seconds.

⚡ Highlights

🧲 Magnetic System
All modules simply click into place – no screws, no tools

🔁 Quick Change
Swap adapters in seconds – perfect for flexible setups

🔒 Precise Seals
Laser-cut seals ensure optimal sealing and minimal air loss

🛠️ Stable Base
Base plate is securely screwed in place – safe and durable hold

Important note

For installation, it is necessary to cut a 125 mm diameter hole in the tent wall. This intentionally alters or permanently damages the material of the grow tent.

After correct assembly, the wall duct sits very firmly due to the bolted sandwich construction. The load is evenly distributed, which largely prevents the tent wall from tearing out.

Nevertheless, use is at your own risk. We assume no liability for potential damage to the grow tent or consequential damages arising therefrom. This applies in particular to damages that may result from improper assembly, external influences, or unforeseen stresses.

How this solution came about

The idea for this system arose from a simple problem: Existing solutions for supply and exhaust air in grow tents are often impractical, leaky, or difficult to adapt. Hoses often have to be improvised, light penetrates, or modifications take time and effort.

Another common problem is that grow tents often lack sufficient or strategically placed openings. This severely limits the positioning of supply and exhaust air or forces reliance on makeshift solutions.

Especially with changing setups – such as adapting supply and exhaust air or using different components – a flexible yet clean solution is often missing.

The goal was therefore to develop a system that is stably mounted, reliably sealed, and can be quickly adjusted without tools. The modular design and magnetic attachment resulted in a solution that precisely meets these requirements and significantly simplifies everyday use.

Perfect fit and airtight

Laser-cut, self-adhesive seals ensure that the connectors close cleanly and are reliably tight.

Robust fastening and reliable hold

The basic construction is stabilized by a total of 12 screws, which firmly connect the two sandwich panels. This ensures that the tent wall is clamped evenly and effectively prevents tearing.


Strong neodymium magnets ensure a firm fit of the modules and a reliable connection.

Quick assembly

Quick and stress-free disassembly and assembly of components: Thanks to the magnetic quick connectors, individual exhaust air components can be detached and reconnected in a few seconds.

Flexible hose connections


Modular hose adapters allow for easy adaptation to different hose diameters. Available in 100 mm, 125 mm, and 150 mm for maximum flexibility in supply and exhaust air systems. Quickly interchangeable and precisely integrable into the system.

Mounting Plate for Active Supply Air

Adapter plate for mounting 140 mm PC fans for active air supply. Enables easy integration into the modular system and ensures a uniform, controlled air supply. Ideal in combination with the matching light trap

Light trap with filter

While many light traps from other suppliers are only partially light-proof, this system achieves almost complete shielding. The integrated activated carbon filter also provides an additional filtering function.

Lid as a closure

Precisely fitting closure cap for securely sealing the opening. Ideal for temporary or permanent closure of unused connections. Can be installed without tools and reliably seals thanks to the precisely manufactured gasket.

Frequently Asked Questions about Breakthrough Bleeding

Yes, installation requires a 125 mm diameter hole. This is the only way to securely mount the base plate and ensure stable use of the system.

Yes, all adapters and modules are magnetically attached and can be replaced at any time without tools. This allows the system to be flexibly adapted to different requirements.
