If you are planning to build an indoor hydroponic grow room you will need to install a ventilation system to supply fresh air into the room and extract hot stale air from the room and the easiest way to do this is with some fans, fittings and of course ducting.
Aluminium flexible ducting can be used to connect all your ventilation items together to create a sealed passage that will allow the air to travel through it in the direction of the flow of the fan, either supplying or extracting air from the room.
When installing your aluminium ducting make sure to keep your runs taught and with as little bends as possible, as too many bends will greatly reduce your flow of air. Aluminium ducting can be connected with duct tape, foil tape or for the best solid fixing we recommend you use a jubilee clip.
