We all love cracking open a container of our favorite bud and taking a big whiff, but the stank of your personal stash is nothing compared to that of an entire grow operation. The whole neighborhood definitely doesn’t need to smell what we are growing. Fortunately, there are a few things we can do to minimize the potent odors coming from our grow room.
Why does my bud smell?
The answer to this is simple; Cannabis contain terpenes. Terpenes are the pungent oils that give cannabis flowers their unique distinct taste and smell. Over one hundred different terpenes have been identified and each one has a unique smell and taste.
How can I control the smell of my grow?
Respecting your neighbors by not polluting the air with the odors of your grow will be greatly appreciated. There are a handful of techniques out there that growers can use to neutralize, remove, or cover up the smell of their grow operation.
These are the gold standard for smell control. Sometimes called “carbon scrubbers”, these devices will pull smells out of the air by neutralizing odors that pass through. Way to Grow has a selection of carbon filters to choose from.
- Highly effective
- Easy to maintain once setup
- System is built to last
- Requires a system that will push air through the filter
- Can be costly
- Filters must be replaced frequently (every 2-4 months)
Unlike carbon filters, these products do not scrub smell from the air. They are designed to bind with potent smells, as well as to counteract them. We recommend ONA products as the go-to odor neutralizer for your grow operations.
Warning: Do not use during the flowering stage, as the products may affect the taste and smell of the product. It is recommended to use these products directly outside your grow room.
- Ideal for smaller grow operations
- Can negatively affect flowering plants
- Must be replaced frequently
- Not as effective for larger gardens
These products claim to remove odors, clean the air, and kill mold and mildew. Ozone is a gas made of three oxygen atoms that will break apart and bond with the terpenes. However, in high concentrations, they can be harmful to plants, animals, and humans. This product does not come with a high recommendation.
- Eliminates smells
- Harmful to health
- Lung irritant
- Banned in California
- Not as effective as carbon filters
These products are meant to reduce odors through a filtering process. They are built to pull air across an internal filter.
- Compact size
- Simple to use
- Not strong enough to handle smells of medium to large grow operations
- Marginally effective
This is new technology in the cannabis world. Bio filters have been used as odor control in other odor producing industries, such as the livestock industry, for years. A bio filter is essentially a stockpile of organic material, such as wood chips, that is inoculated with bacteria that will naturally consume odorous molecules. Tantalus Lab is undergoing the first tests to see how these bacteria process terpenes, initial tests are promising.
- All natural and organic
- Cost effective
- Still under testing
The More You Know, The Better Your Grow
There is a myriad of solutions to your stanky grow room problems. The key is finding the right solution for you. If you are running a larger operation, it may be beneficial for you to invest in a long-term solution like a carbon filter. If you have a small home grow room, you may be able to use odor neutralizers and save a little dough. Although ozone machines work, they are harmful to your health and you should probably steer clear of them. Keep your eyes peeled for up-and-coming odor reduction technology. In an industry growing as quickly as the cannabis industry new and improved methods are popping up often.
