how to control the smell of growing weed

For a small grow with just 1 or 2 plants, you can usually get away with covering up the smell.

These devices use activated carbon to chemically absorb smells and other impurities from any air that is pushed through the filter.

Most household products like wall plug-ins and sprays just aren’t strong enough to cover up the smell of a marijuana grow room for long, if at all.

How to Find & Install The Right Carbon Filter.

With a carbon scrubber, you need to set up a situation where the smelly marijuana air is being forced through the filter. In other words, you need to use a fan to push or (even better) pull air through the carbon filter.

If you need to neutralize the smell coming out of your exhaust , a carbon filter (#1 on this list) is highly recommended. You could also have your exhaust air blow over an Ona product right before being vented outside. It is not recommended to use Ona products in your grow area alongside your plants. Ona products are meant to be used outside the grow area.

I’ve heard of growers using everything from incense to “bathroom sprays” to cologne to try to cover up the smell of a flowering marijuana plant.

Unlike a carbon filter, odor neutralizers don’t “scrub” the smells from the air.

You don’t even have to attach the fan to anything, you can just let the scrubbed air go back into the room. It’s pretty amazing how fast this can clear up a smelly area! I learned this from a dispensary owner. Here is an example of a fan/carbon filter combo.

A grow room with flowering marijuana plants is a factory for that delicious tell-tale smell, and to protect your girls, you’ll have to make that smell a non-issue.

Why 6 inches? 6″ fans are strong enough to exhaust the air from nearly any small-scale grow. Unlike 4″ fans which are often too weak for 4″ carbon filters & will not fit standard air-cooled grow lights. 8″ and bigger filters are generally for more commercial applications; they require extremely powerful (and expensive $$) fans suitable to moving huge amounts of air from a large enclosed area, plus they can’t be hooked up directly to standard grow lights.

Ozone generators are sometimes added to grow rooms to neutralize smells. Ozone generators claim to remove odors, clean the air, and kill mold and mildew.

It is true that some air purifiers do help remove some smells from the air. However, these are not strong enough to pull all the smells from a grow room. These are only marginally effective.

Best spray to cover up smells in an emergency: Ozium Air Sanitizer – this smells very “citrus clean” that seems to do pretty well at covering up cannabis odor without smelling like you just sprayed a bunch of Febreeze. The only thing to keep in mind is a little bit goes a long way. A quick spritz is all you need!

These are hands-down the best option for controlling marijuana grow room odors. Carbon filters (also called ‘carbon scrubbers’) will actually pull the smells out of the air, neutralizing any odors that pass through.

Note: It is recommended you do not place these products in your grow room or tent with flowering cannabis plants. Strong odor neutralizers work so well they can actually reduce or alter the flavor of buds over time. However, these are incredibly effective at neutralizing odors outside the grow area.

Refer to the diagram below to see how a carbon filter should be set up in your exhaust system. The carbon scrubber being placed at the back of the exhaust system minimizes the risk of flowering cannabis smell escaping.

If you use Ona products in your living room, den, or other open areas, no one who enters those rooms will be able to smell any sign of your cannabis plants, even if the plants are just a room away.

Therefore, while air purifiers may be a good choice for other reasons, I do not recommend getting one just to try to get rid of smells in your grow room.

For those living in matchbox homes or houses with close proximity, maintaining an indoor grow farm becomes a challenge. For this, odor control is a crucial aspect.

Any of these factors left unchecked could result in the plants letting off more odor than usual and more often than not it is an indicator of poor growth conditions within the grow room.

Odor control helps keep the smell low and prying eyes away from the grow room.

Sign Of Poor Health.

A fundamental aspect of controlling the odor in an indoor grow room is to manage the temperature and humidity.

When it comes to controlling the odor, there is only so much that can be done when it comes to making the environment around it better.

Grow Year Round.

The easiest way to tackle this is to install fans in the grow room.

Are there effective ways to control cannabis odor? There are various ways to control weed odor. These include: ensuring proper air circulation, installing an activated carbon filter, use ozone generators, fitting surface and air purifiers, using odor absorbing gels and keeping room temperature in check.

Using any of the above-listed solutions, either by themselves or combined, does not cost a lot when considering the benefit they provide to the whole process of indoor cannabis growing and the peace of mind that comes when the room is scent-proofed.

Neighbors.

Another effective solution for commercial indoor grow spaces is fitting surface and air purifiers. Due to their size and capacity, these are best suited for large cannabis grow rooms.

Harvest up to a pound.

It’s not a huge surprise to anyone that cannabis smells. It has a very distinct, pungent, and lingering smell that is widely recognized.

It is important to remember that as pleasant as growing cannabis is, not everyone shares the same opinion.

Security and Safety.

Excess odor can be an indicator of a poor growing environment for plants. From the ventilation to air-circulation and temperature, there are a lot of factors that play a key role in cannabis growth and farming.

While it is easy to ignore odor control, there are several reasons why a large-scale indoor cannabis grow room should be odor-controlled.

By getting rid of such unwanted particles, the odor in the room is naturally reduced to a more tolerable and ideal level.

These machines constantly work on making the air in the room better. They do so by removing airborne particles including mold, dust, smoke, pollen, viruses, and bacteria.

While the smell is tolerable and fleeting on small grows and with single plants, it does tend to get inconvenient for long-term, large scale grow-ops.

Before you actually start growing cannabis indoors you’ll need to make sure that air gets in and out exactly where it’s supposed to; any leaks would be disastrous and would defeat the point of hiding the smell. Once you’ve checked everything and set up your filtration system (which needs to be strong enough to filter the amount of air in your grow tent or room ) you need to make sure that your extractor and air intake system is creating negative pressure, which makes sure that all of the air inside the tent or room will be sucked out via your extractor fan rather than leaking out anywhere else.

One of the best activated carbon filters is the Mountain Air filter , which is so efficient that it has won prizes for it. These high quality filters made in Canada can filter almost 100% or any aromas thanks to its high quality activated carbon and its innovative design and shape. They usually last for about two years, depending on how intensely you plan on growing cannabis. These filters are perfectly safe and eco-friendly .

Ozone generators are some of the most effective devices when it comes to getting rid of the smell of cannabis in grow rooms. They’re capable of destroying odor particles one by one, as well as any type of fungi or bacteria in the environment . When used, you need to take extreme care and make sure that no ozone gets out of its contained area in your ducting; it’s incredibly devastating for your plants and even for people.

How to Hide the Smell of Growing Weed Indoors | Before growing.

Odor filter + Neutralizer + Gel; You can install an activated carbon filter, odor-killing gel inside your ducting about a meter away from the extraction fan outlet and a Neutralizer at the entrance to your house.

ONA gel products can be used inside cannabis grow rooms or tents without damaging the plants at all. These products are generally used to back-up carbon filters by placing them inside your ducting. They’re also used to camouflage the aroma when drying cannabis or for areas near your grow room like the hall or your garage. You can also acquire sprayers and the like so that you get the absolute most out of it .

Carbon filters are classic cannabis filtering devices . Not all carbon filters work the same when it comes to filter power and lifespan; you may want to pick a high quality device – you may need to shell out a bit more money. You’ll also need to pick one that’s right for your extractor or else it won’t work correctly.

When growing cannabis indoors it can seem like a losing battle when it comes to hiding the smell. Cannabis plants let off intensely pungent aromas when flowering, and these aromas can filter out and end up stinking up your entire building; in some cases it may even end up sticking up the block next to you too. This can obviously lead to issues with the law, as well as opportunistic thieves that want to get their hands on your plants. That’s why you need to know the best tips and tricks regarding how to hide the smell of growing weed indoors.

Neutralizers are products created from various different plant extracts and chemical products. They are capable of trapping, modifying or even destroying cannabis odor particles with incredibly efficiency. These types of products usually come with a small electric diffusor that is used to heat the mix and spray it around the room.

A decent ozone generator is the Uvonair generator, which uses a diffusor crown to produce ozone; you’ll need to replace it every now and then. Like every other ozone generator on the market, you’ll need to place it right before your extractor fan outlet. It should have at least 5m of ducting in front for it to work properly. In order to avoid issues with ozone leaks, we recommend using a non-return valve in between the extraction fan and the ozone generator. Place your intake fan on the opposite side to the extractor, down low.

Activated carbon filters.

If your grow tent walls seem to be filling up and expanding outwards your intake fan is much too strong and your extractor fan isn’t strong enough to absorb all of the new air being taken into the tent. When growing in a room it’s much harder to realize that this is an issue – you’ll know when you start to small cannabis outside the room.

One of the best ways to guarantee total odor filtration and stop the aroma of weed getting out of your room or grow tent, is to use various products at the same time. Let’s have a look at some examples:

The Neutralizer is one of the best odor neutralizers that we stock. It’s made from various different essential oils from aromatic plants and it modifies cannabis odor particles perfectly, capable of covering large areas effectively. It does not affect your plants’ aroma and it’s perfectly fine to breathe in.

If you want to make your grow as discreet as possible you’ll need to set up a decent air filtration system, as well as some sort of anti-odor method that covers, gets rid of or filters the smell of cannabis. We’re going to give you a run-down of some of the best methods that you can use to hide the smell of cannabis plants indoors, which can save you a lot of grief in the future .

Odor neutralizers.

When it comes to getting rid of pungent aromas , you’ll need to pick your preferred method or system; each method has its own pros and cons, which is why it’s a good idea to test them out and then maybe combine two of them for the best possible results – your weed won’t be stinking up anywhere any time soon if you follow our advice. The largest difference between these methods tends to be how pricey they are, which is why it’s a good idea to combine more than one method at a time.

One of the best anti-odor brands out there is called ONA ; they produce many different products including air fresheners as well as products that can be sprayed to get rid of the smell of cannabis in a flash. They also come in blocks, which are more compact than the gel format , which slowly release a combination of pleasant, nice aromas that are perfectly safe.

On the one hand you can use air fresheners or odor neutralizers , which can be found in gel or liquid format and are generally used as an extra measure – they usually aren’t potent enough to do the entire job themselves when plants are in bloom. On the other hand you can also use activated carbon filters, which usually come in fabric or metal casings and are used by attaching them to your extraction fan system; they can filter up to 90% of all odors . Last, but not least, you can also use an ozone generator, which is also installed to your extraction ducting, however you must not let the ozone come into contact with your plants.

Odor Filter + Two Gels; This method involves installing a metal activated carbon filter in your ducting system and using two gels for extra precaution; one at the entrance to your house and another inside the ducting right before your extractor fan.

Tube Ozone Generator + Gel or Neutralizer; This method consists of using a tube ozone generator in your grow room and either ONA gel or a Neutralizer at the entrance to your home. When using a tubular ozone generator, you won’t need a no-return valve to avoid leaks.
