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.
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.
How to hide the smell of growing weed indoors | Before growing
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.
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.
Anti-odor products
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.
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.
Anti-odor gels
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.
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.
Odor neutralizers
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.
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.
Activated carbon filters
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.
One of the best activated carbon filters is the Anti-odor Filter Mountain Air, 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
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.
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.
100% Odor filter combinations:
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:
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.
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.
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.
