Ventilation & Odor Control Kits

Grow Room Ventilation & Odor Control Kits for Indoor Grow Rooms

There is nothing quite like the smell of a rich and pungent garden. It’s an aspect of growing plants that many gardeners love and look forward to.That is until the odor has engulfed your house and is sneaking its way over to your neighbors. Controlling odor often requires setting up a system dedicated solely to tackling it. Certain plants can be so pungently overwhelming that one plant alone can consume a multi-level house in its entirety with its odor.

Controlling odor is a necessity for both cleanliness and privacy, and failure to control it can spell disaster. But that’s not the only reason you want to set up a ventilation and odor control system.

Why Ventilation And Air Circulation Is Important in the Garden

A poor ventilation system will lead to:

  • Depleted CO2
  • Dangerous temperatures and humidity levels
  • Pets and infestations
  • Dust buildup

Dust building up is something a lot of new growers don’t think about, but if you allow it to build up onto your lighting system, you will affect your light’s intensity costing you yield and money.

Make It Easy And Go With An All-In-One Kit

Setting up a proper ventilation and odor control system can seem daunting at first, so many skip setting up one. More likely though, they put together a shotty system with fans placed in counterintuitive locations and attempt to mask the smell with sprays and pluggable scented oils. Plants will absorb particles in the air and this includes sprays you use for masking. This means you can jeopardize and alter the way your plants smell and taste, plus they don’t even cover the smell that well.

That’s why we put together easy to install complete ventilation and odor control kits, so you can rest assured that you have a great system in place without having to do really any homework first.

The Right Fit for your Grow

Our kits come with fans and speed controller, ducting for ventilation, and a carbon filter for odor control. They are easily installed into the grow tent of your choice, you’ll want to match ducting size, which won’t be a problem since we offer the following ducting sizes: 4”, 6”, 8”, 10” 12”.  

It’s recommended to exchange all the air in a grow room every 1-5 minutes, so you need to find out two numbers to ensure that your fan is powerful enough for the size of your grow room. First, you will want to calculate the volume (cubic feet) of your grow area / grow tent, which can easily be done by multiplying Length x Width x Height.

As a rule of thumb, when using a carbon filter – which our kits provide – you want a fan that has a CFM rating twice as large as your tent’s volume. So if your tent is 40 cubic feet, we recommend a fan that has a rating of at least 80 CFM. CFM stands for cubic feet per minute, and essentially tells you how much air the fan can move per minute.

Carbon Filter vs. Odor Neutralizers

You might wonder why we only offer carbon filters in our kits, the answer is simple really. Carbon filters effectively eliminate odor, they do not alter or harm your plants in any way, they have a long lifespan, and they work perfect with ventilation systems.  

Their one real negative is they do have a higher initial cost than other viable odor control methods, like ONA products for example.

ONA is a company that creates a range of popular odor neutralizers that are commonly used in sewage plants, so they work well to eliminate odor, and they are fairly affordable as well. Unfortunately, they will need to be replaced often, and they must be placed outside of the grow room as they will alter the plant’s aroma. Since they can alter the smell of your plants, ONA odor neutralizers will produce a smell of their own.  

Now, it is true that a carbon filter will need to eventually be replaced every 12-18 months, but ONA products may only last a couple months. That might not even get a grower through one growing cycle.

In our professional opinion, and many other professionals will back this up, a carbon filter is without a doubt the much better option as they eliminate smell to a greater degree and run no risk of alternating your plants.

Assembly and Installation

There are two main ways you can set up our ventilation & odor control kits: the fan can be directly mounted onto the flange or the ducting can be placed between the flange and inline exhaust fan connecting them. The flange will always directly attach to the carbon filter.

What method of installation will come down to the grow room size, what your ceiling looks like for hanging, etc.

Let’s take a quick look at what a popular ventilation and odor setup looks like when using HID grow lights as it’s a very common configuration. Carbon filter / flange -> ducting -> HID reflector hood -> ducting -> fan. As you can see, you can have a lighting system in between the two units.

This is a great setup, and the only thing you need to be aware of is how you stretch the ducting as it can’t hinder airflow. It should be as short and straight as possible for efficient air circulation. Slight twisting is ok, but avoid 90 degree angles at all cost. As well, the more ducting you use the harder you extraction fan will have to work, so make sure to keep ducting to a minimum.
