How to Install a Cooltube in your Grow

How to Install a Cooltube in your GrowIn this article we’re going to show you how to install a cooltube in your indoor cannabis grow, which is quite a simple task if you’ve done it before but if you haven’t it might seem more complicated than it actually is. When setting up your grow for the first time you probably had thousands of questions such as where to connect the cooltube, the extractor, or issues such as how to place the odor filter. After reading this article hopefully you won’t have any more questions as we’ll have answered them all!

The first thing we’re going to talk about is how to set up the circuit for ventilating your grow room or grow tent. You need to pay attention to the path that the air goes through in the circuit and see where you should put each accessory for your grow. It’s also important that you have some decent metallic adhesive tape that can easily put up with heat and won’t come unstuck easily, because you need to make sure that the connections between tubes and devices have absolutely no holes in them, which could cause a smell leakage – if your budget allows, clamps would be even better.

As you can see in the picture, number one is the carbon filter, which is the first thing that you’ll need to have in your ventilation system in the first place the extracted air is going to pass through. Then, you’ll need to connect the extractor to the filter, or like in the picture you can join them together through a small bit of tube. The next piece is a flexible silencer, with which you’ll be able to remove a lot of noise from the extraction – this is one of the noisiest things in your grow.

Next, you simply place the tube that is going to be extracting the air outside, which is the perfect spot to place your ozonizer – after the ozonizer there needs to be at least 5m of tube or cable before the extraction point to the outdoors. If you use a soundproof pipe you’ll reduce the noise level even more than before.

Now that you know how to install a normal ventilation system, we’re going to explain how to install a cooltube in your grow or a refrigerated reflector in between your ventilation devices. You cando this two ways – one is making the ventilation air pass through the reflector, and the other way involves making a whole other circuit just to cool down the bulb.

How to Install a Cooltube in your Grow


As you can see, installing a cooltube by integrating it into the ventilation system is quite easy – you need to ensure that your ventilation system is blowing towards the bulb and that that air leaves the grow alongside most of the heat created by the bulb itself.

First, you need to place the odor filter connected to the extractor – the flexible silencer will dim the noise from the air flow, and the tube will connect everything to the cooltube or a refrigerated reflector – to get one of these reflectors you can check out the wide variety that we have on our webpage.

This is done so that the hot air from the bulb doesn’t go through the air extractor, which can avoid possible breakage due to excess heat in the extractor. Of course, although there’s only one cooltube in the photo you can place as many as you want all lined up – depending on how many you have you’ll need more or less extraction.

There’s another way to install cooltube reflectors in your grow, and this method might even be better if you have a lot of reflectors or cooltubes connected in a row. What you need to do is set up a circuit for ventilation and another one to cool down the reflectors.

In this picture you can see an example of what we’re talking about – in the picture you can see the ventilation circuit with its odor filter, extractor, flexible silencer, non-return valve and then out goes the air. The lower circuit, however, is another ventilation circuit that goes through the reflector and out of the grow. The air that goes through this circuit comes from outside the grow and goes back outside the grow when the circuit is complete, so you don’t need any filters or odor fighting systems.

How to Install a Cooltube in your GrowYou can also see how it has a soundproof box with an extractor and an in-line extractor. The box is used to slice the extractor, as the air is taken in straight from outside and the noise can be heard through the tube. Then you place the tube that connects the cooltube extractor and it has an in-line extractor to help move the air quickly if you have lots of bends or many devices lines up.

If you have a decent extractor then you can remove the in-line, and if you have over 10m of tube in your grow then you’re better off using in-line extractors to help out the main extractor.

Now you know how to install your cooltube in your grow! If you have any questions or issues, don’t hesitate to leave a comment and we’ll get back to you as soon as possible.
