Cannabolish uses natural plant oils and water, a blend they’ve spent years perfecting.

How to use Cannabolish:

Spray a few pumps in the area containing strong cannabis odor. The compounds in Cannabolish attach to the odor molecules and break apart the chemical bonds causing the odor. Once the bond is broken, the cannabis odor is neutralized.

Cannabolish is perfect for use around sensitive people and animals. In fact, the indoor Cannabis Cafe in California, Lowell Farms, uses Cannabolish products to reduce odors and keep the environment friendly for customers who are actively consuming cannabis!

2. Grow Tent – An Enclosed Structure Is Better To Keep Cannabis Smell Inside

Growing weed indoors is a fun activity, but if you want to control the odor from your cannabis plants, using a grow tent with a carbon filter and fan is the best way to do so.

Using a grow tent is much more efficient because light from your LED grow light will be reflected back onto your plants instead of being wasted into open space.

A few other benefits include a perfect shelter for plants, prevention of bugs and the ability to control the climate. All of these features ensure you’ll be able to get the maximum harvest from your cannabis plants.

A grow tent won’t keep 100% of the smell from escaping. Every time you open it some odor will escape. However, keeping your plants in an enclosed grow tent with a fan and carbon filter to scrub the smell is a major step in the right direction.

3. Odor Neutralizers

best led grow lightsEven if you use grow tents, you’ll still be opening them up occasionally and inevitably some marijuana odor will escape.

Maybe you aren’t even growing marijuana, but consuming it in your home or car. In that case odor neutralizers are also a great option.

Most people try to use body spray, cologne or perfume to hide marijuana smell. Unfortunately you’re not only wasting expensive scents, but using ineffective ones. They never work completely because they aren’t scientifically designed for odor neutralization.

Check out the EJ Wheaton odor neutralizer shown above and you’ll never turn back. The best part is it’s likely more affordable than your perfume!

These neutralizers are designed in such a way that they blend along with the real smell and create a neutral effect of fragrance.

Also, there are multiple options available on the market by using which you can convert the smell of marijuana in your preference of aromas like jasmine, rose or mint.

4. Carbon Filter With Inline Fan For Fresh Air

If you’re using an inline fan for ventilation on your grow tent, the fan only blows air. Unfortunately it’ll be blowing the smell of cannabis all around your home unless you buy one of these carbon filters.

As seen in the image above, they attach to similarly sized ducting as well as your grow tent’s inline fan. Turn the fan on and you might as well be breathing fresh mountain air. On the outside you’ll never know if you were growing tomato onion or cannabis inside your tent.

The basic working of the carbon filter is to absorb excessive bad air available in the space and to balance normal air circulation. Yeah, when potential smelling air pass through this prop, it absorbs all the elements responsible for creating the aroma into it and what left is just routine normal air.

Also, attached benefits of carbon filter give a reason to think about its inclusion in your grow space tool or props.

Yeah, carbon filters are an economical way of balancing air or odor treatment.

Also, they last longer than any other alternative such as odor neutralizers, or air purifiers.

Carbon filter placement and fitment is one-time activity, and they don’t intervene again in your entire growing journey. Yeah, in case of air purifiers and odor neutralizers you may need to change positions and also need to test them for a proper outcome. Carbon filters are meant to be attached with the exhaust system, and that’s it.

The carbon filter isn’t an alternative, and it is more like a solution. Yeah, in case of other props you may not get routine air in your house. Instead it’ll either replace kind of smell with different smell which gives a reason to curious people to suspect your house situations. While carbon filters replace odor filled air with new fresh air which is normal for you as well as for others.

5. Air Purifier – Convenient and Easy Way of Hiding Cannabis Odor

Air purifiers are a solid tool to keep your air clean from particles of cannabis smoke that may be causing odor. They’re also a good supplemental tool to keep the air fresh if you’re growing in a nearby room.

This Levoit air purifier is a modern, affordable and stylish air purifier that’ll help you maintain that environment. It’ll do that with the three stage filtration system that consists of a pre-filter, true HEPA filter, and the High-Efficiency Activated Carbon Filter.

This thing runs really quiet and filters air down to 0.3 microns! That’s an incredibly small and invisible to the eye size. It also comes with a 2 year warranty in the unlikely event anything goes wrong.

You don’t need to take it from me. Check out the thousands of positive reviews on Amazon.

6. Smell Proof Bag with Combination Lock Odor

Need a place to store your stash without letting others know where and what you’re keeping?

Odor proof bags can be a great, very affordable solution and a decent amount of storage. The OZCHIN smell proof bag displayed above is lined with 8 carbon fiber layers and water-resistant nylon to lock in odors and hide smells.

It also features a lock to help keep your stash safe.


7. Place These Charcoal Carbon Filters over HVAC Air Vents

This is the same concept as using the carbon filter inside of a grow tent, but instead of inside your grow tent, it’s in the room in your house. Readers have asked me how to prevent the cannabis smell from exiting their homes. Placing a charcoal filter over your air vents is my recommendation. 

For example, you may open the grow tent in your bedroom and the odor may escape into your bedroom, and exit through an air vent if your door is closed. But if you have one of these odor scrubbing carbon sheets over your air vent, it’ll help keep the odor from traveling to other rooms in your home. 

We know the charcoal filter eliminates odor from inside grow tents when it’s attached to a fan that pumps air out of the grow tent. So this method will work in the same fashion when it’s connected to your home’s air vents.

8. Check Your Ducts for Air Leaks

It’s possible your ducting has a small hole that’s releasing a lot of cannabis smell in your grow space. One way to check your ducting for a leak would running soapy water over it then turning on the fan. If you see a spot with bubbles you’ll know there’s a leak.


9. Grow Low-Odor Cannabis Strains

In the near future I suspect there will be genetically modified cannabis strains that result in a plant that produces little to no terpenes. Terpenes are the oil produced by the cannabis plant that make the strong odor.

For the time being, you can try growing strains that are known to produce less smell than others, although it won’t be perfect. Maybe just easier to manage.
