Ducting
Shop grow room ducting in a range of styles and diameters, from traditional aluminium to acoustic and light-tight combi ducting, sourced from G.A.S and PhonicTrap. Quality ducting reduces noise, prevents light leaks, and ensures efficient airflow throughout your ventilation system.
Choosing the right ducting type
Standard aluminium ducting is the most affordable, reliable option for basic ventilation runs. Acoustic ducting adds sound-dampening insulation, valuable if noise is a concern (shared walls, living spaces nearby). Combi ducting combines an aluminium inner layer with a flexible outer layer, improving tear resistance and — in black variants — preventing light leaks that could disrupt your plants' photoperiod.
Diameter matters for airflow efficiency
Ducting diameter should match your fan's rated output — undersized ducting creates airflow resistance, forcing your fan to work harder and less efficiently, while correctly matched ducting maintains your fan's intended performance.
Non-allergenic insulation
Several of our acoustic and premium ducting options use non-allergenic insulating materials rather than traditional fibreglass wool — an important consideration, since damaged fibreglass ducting can release irritating shards into your grow environment.
FAQ
What ducting diameter do I need?
Match it to your fan's inlet/outlet size — using a smaller diameter than your fan is rated for will restrict airflow and reduce ventilation efficiency.
Does ducting length affect performance?
Yes — longer duct runs create more airflow resistance, so try to keep runs as short and straight as practical, minimising unnecessary bends.
Is black ducting necessary, or just a preference?
For light-tight requirements (preventing any light leak into or out of your grow space during dark periods), black combi ducting is genuinely functional, not just cosmetic.
