What’s the big deal?

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.

Make sure the “CFM” rating of the carbon filter is the same or slightly higher than the one listed on your fan. This ensures maximum efficiency but also has an added security benefit: it makes sure your carbon filter is only taking in as much air as it can effective scrub for odors.

Well, ignoring the fact that Ozone is not as effective as a carbon filter at reducing odors, one problem is that they’re bad for the environment. So much, in fact, that they’re illegal in the state of CA where I live (see:

Generally, they seem to last at least 4-6 weeks for most growers, which is long enough for a few of these to provide coverage throughout the smelly second half of the flowering stage.

1.) Identify the diameter of your exhaust

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.

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.

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.

Note: Glass blocks most UV light, so if your light is separated from your plants by glass (for example by a greenhouse or hood) it will prevent a lot of the UV light from reaching your buds. When it comes to UV light, there should always be a clear and direct path from the light source to the plants.

When it comes to nutrients and supplements, you have several choices that can help improve the overall scent of your buds. In fact, many products have been formulated specifically to increase and enhance the smell of cannabis buds.

These strains are either particularly pleasant smelling or have a downright pungent odor. There are growers who want both kinds. The strains below have been hand-picked by us because they’re exceptionally strong and aromatic, as well as being stable strains from known and trusted breeders.

3.) Grow in “Living” Soil (Super Soil)

Do you want to improve the smell of your cannabis? Ready to defeat “hay smell” for good? When it comes to homegrown cannabis, the smell of your buds contributes greatly to the overall perceived quality. Just like how food tastes better when it smells great, producing buds with a great smell can greatly improve the overall experience. In addition to strains with “common” weed smells like diesel and skunk, there are also strains that produce exotic fruity and sweet smells like pineapple, blueberry, or chocolate. We’re even learning that certain combinations of terpenes (which cause the smell of cannabis) can change or increase the perceived potency.

These claim to help remove buildup of nutrients or other unwanted compounds. They don’t seem to hurt anything though I have yet to see significant evidence of measurable improvement to buds. Contact us and let us know what you think!

However, they’re not equal when it comes to increasing the level of smell. There is some evidence that some types of light, specifically a type of light known as UV-B light, can possibly enhance trichome production and smell. This is backed up by the fact that grow lights with high UV productions often produce some of the highest levels of terpenes in lab tests.

Having somewhat cooler nights can help cannabis produce more terpenes, and cooler night temperatures towards the end of the flowering stage also helps bring out colors like pink and purple if your plant has the genetics.

The impact of air circulation in different phases of plant growth is well known. Proper air circulation keeps the temperature and odor levels low while recycling used CO2 out of the indoor grow space.

Due to their effectiveness in purifying the air and getting rid of various contaminants such as mold, bacteria, odors, and pests, they tend to be on the more expensive side of options when it comes to odor management.

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.
