Ducting comes in a range of popular standard sizes, namely 4", 5", 6", 8", 10" and 12". Bigger sizes have started to appear lately but these ones form the core of the market.

Ducting comes in two main forms, rigid and flexible. In both cases there are various qualities and grades to create further subcategories but we'll get to that in a minute...

So what's the difference between rigid and flexible? Well, as you may suspect, rigid ducting comes in solid lengths of rigid material, usually metal or plastic with the former being the premium and most robust option and the latter being the budget. Along with lengths of pipework, various fixtures and fittings are available to enable you to create ducting runs with angles to follow around corners, split the ducting in various ways or to connect lengths of different sizes. These bends and splitters are also completely suitable for use in flexible ducting runs.

Flexible ducting is by far the most sold ducting component in the world of hydroponics, there are two main subcategories: standard and acoustic, the difference being that the latter has a thick lining of sound deadening material to reduce wind noise where that is a problem. The most basic form of flexible ducting is plain aluminium foil surrounding a wire coil, this does the job but is prone to tearing. This issue is addressed with the most popular category of ducting sold today, combi ducting, aluminium foil ducting with the addition of a plastic jacket to improve tear resistance and avoid small rips or tears creating big problems in your air flow set up.

When adding your ducting components to the basket don't forget to double check to specify the correct size and length for your project along with any extras you may need like duct tape and fast clamps to get that perfect seal and ensure no undesirable odours escape or lost efficiency from your fans or filters.

Getting started on your ducting project or installation...

You don't need an instruction manual to design and install your ducting project, just a bit of common sense and a few basic tools will do the trick. It's wise to always start by thoroughly measuring your grow room and the areas where the ducting will need to go. Keep in mind that ducting runs should be kept as short as possible as every extra inch adds to the total air resistance that'll have to be overcome by your fan. In other words, the shorter the run, the less work your fan will have to do and the happier it will be, especially when temperatures start to rise.

I've taken my measurements, what's next?

Once you're all measured up you'll likely have a good idea of what length you'll need, remember to keep your runs as short as possible but also buy enough to account for mistakes and accidental damage to avoid a second trip to the grow shop or internet order.

Buy the largest duct size you can justify. Why? The larger the duct size and the more powerful the fan, the less air resistance and the less hard the fan will have to work. This will result in less wind noise and more power in reserve for really hot summer days when a smaller fan just wouldn't be able to cope. Don't forget that if you're growing in a tent your maximum duct size will be dictated by the duct port size so remember to measure carefully.

Do I need rigid or flexible ducting for my grow room?

If your grow room is a permanent installation that you are not anticipating having to move any time soon then certainly consider going with rigid ducting, it'll generate far less wind noise and is much stronger and hard wearing compared to flexible.

Flexible ducting is more appropriate when the installation is more temporary in nature or when there's a chance you may need to move or disassemble in the future.

Do I need Acoustic Ducting?

That depends. If you're suffering from a lot of wind noise or you're anticipating that you will because your set up demands you couple a powerful fan with smaller sized ducting or your ducting run will be long or will go around many bends and corners then you may want to consider acoustic ducting. For most people it's not necessary.

Now you've decided on the size, length and type of ducting you need to turn your ducting dreams into reality, visit the Ducting and Ducting Components section of our store to start adding the items you need to your basket and we'll get them shipped to you as quickly as possible.

Installing the Ducting in your Grow Room

As mentioned previously you don't need many fancy tools to install ducting. Most of the time a knife, a pair of scissors, some wire cutters and a roll of duct tape is all you'll need. When installing rigid ducting or ducting components such as flange plates you may well need the addition of a drill and screw driver.
