    Cannabis does smell, there's no getting away from it. Some love it, while others loathe it. One thing's for sure, weed plants emit an often overwhelming scent. How can you neutralize or mask weed odour? How do you get rid of the whiff of cannabis in the house? We have the answers so read on if you would like to find out how to keep your neighbours happy.

    Why does weed smell?

    This might sound like a bit of a silly question, but why does weed smell? The answer lies in the fact that cannabis contains many different compounds.

    The substances responsible for the spread of weed odour are primarily terpenes and terpenoids. These substances often give weed its delicious taste. Weed has a very specific odour - once smelled never forgotten! Weed species can also have different undertones. These undertones are caused by the terpenes and terpenoids. Examples of these undertones are lemon, liquorice, earth, pepper, vanilla, incense, diesel and more. You can imagine that a cocktail containing all these scents would be pungent, to say the least.

    Which strains are low in odour? 

    The smell of growing weed depends mainly on the species. Fortunately there are many species that provide less odour compared to others. Therefore we have created a top 3 with some very interesting low odor strains:

    1. Northern Lights
    2. Green Crack
    3. Jack Herer

    When do cannabis plants start to emit odour?

    Many novice growers wonder when the weed smell can be expected during cultivation. Of course, the more plants you grow, the more fragrance they will emit. Here is an overview of what you can expect during the different phases of the weed growing process:

    Stage Odour
    Germination No smell
    Seedling stage No smell
    First weeks vegetative phase No to little smell
    Last week vegetative phase  Little smell
    First weeks flowering phase Smell becomes more intense
    Last weeks flowering phase Smell strongly presented
    Harvesting Strong smell
    Drying / curing Strong smell

    The odour is different for each strain/type of weed as is the extent to which you can smell the plant. The pervasiveness or strength also varies according to the strain. Most sellers of seeds will be able to tell you which types of cannabis produce extremely strong odours. If you are keen to avoid the smell of weed in the house, it is important to do some research into which species you will grow before investing in your seeds.

    How to control the smell in your grow room?

    Weed odour can be a considerable problem for home growers, especially if they live in a country where the cultivation of cannabis is illegal. When the plants start to bloom, the weed odour increases and neighbours start to smell it with often unfortunate consequences. The police are called and they are at the door in no time. This is annoying for the grower, but, in fairness, unwanted weed odour is pretty anti-social for the neighbours. How can you neutralize weed odour? There are several solutions. The best known is a carbon filter. They come in two forms: large carbon filters for the weed growing room and very small active carbon filters for joints. These are designed to make smoking less damaging for your lungs and to reduce odour during smoking.

    Keep an eye of the humidity and temperature levels of your growing room. The higher the levels of humidity, the greater the odour. Air must be circulated in the growing room to reduce the smell, as well as to reduce the likelihood of mould and viruses that thrive in stagnant conditions.

    Carbon filters in your extractor can vastly reduce the impact of weed odour. You can easily buy a carbon filter online. Placing the filter in your extractor or air filtration system can be a little tricky but it is well worth researching ways to do this. If you want to keep your operation private, the best solution is a carbon filter which can also be used during harvesting and drying. Other types of filters and generators can help you, but they are very expensive and generally only suitable for industrial-scale growers.

    Don't forget to regularly clean and maintain the filters if you want to successfully reduce the odour in your growing room.

    Odour absorbing gels are another option.

    How to hide the smell of weed after harvest?

    After harvesting, drying and cutting, it's time to cure your weed. If you use a normal container, you can guarantee that your entire house will smell of weed in no time. However, weed smell is easy to prevent, you just have to know the correct tools to use.

    Ziplock bags are the most common products for storing weed. Yet these resealable bags are not 100 percent odour-free and airtight. They are more suitable for smaller quantities that will be consumed within a few days. Do you want to get rid of the weed odour and not draw unwanted attention from your employer or neighbours? These are the best options:

    Tightvac containers are the ultimate choice when it comes to storing weed in an odour-free manner. In the lids of these storage canisters, there is a unique vacuum system that ensures that air can go out during closing, but no air can enter. The result: a vacuum storage space. A Tightvac is 100% airtight, odour-free, water-repellent and impressively sturdy. You can store everything in it and even put it in the freezer. They come in all shapes and sizes, and they are affordable too!

    Ironing bags are a very good solution if you want to store weed for a longer time and do not have to add it. Unsurprisingly, ironing bags are closed with an iron. When it is closed shut, the bag is completely airtight and odour-free. If you want to open it, you will need to use a pair of scissors but you only need to cut open the tightly ironed part to reuse the bag. It will be a bit smaller, but luckily buying a new one won't cause too much of a dent in your wallet.

    Storing your weed in a mason jar is old-fashioned, but effective. They are large glass jars that you can open and close whenever you want. The beauty of such a glass jar? You can view the contents and admire the tops you've worked so hard for?

    Some types of plastic storage boxes are also super useful for storing small amounts of weed. Just make sure the lids seal properly.

    You can see that there are plenty of ways you can eliminate weed smells at each stage of the growing process. Don't forget to appreciate the wonderful aroma though, and take some deep breaths of the young plants whenever you feel like it!
