PSA: Don’t use ONA to control smells IN the grow room
by Nebula Haze
A lot of cannabis growers are worried about the odor of flowering (budding) cannabis plants, and may be trying to avoid letting smells leak out of the grow room.
Many of you may have heard of “ONA Gel” or other ONA products.
ONA products don’t just cover up smells, they actually get rid of them permanently!
ONA products are regularly used at dispensaries to cover up the smell of cannabis.
ONA products are powerful stuff and they work incredibly well at neutralizing smells in your living areas, but I wanted to warn you about one thing…
Never let ONA products share air with your flowering cannabis plants! ONA products are so strong they do not have to physically touch your buds in order to have a permanent effect on their taste and smell.
Never put Ona Gels near cannabis plants when they're flowering (making buds)
If air which has been treated with ONA Gel comes in contact with your buds for a significant amount of time, the treated air will begin to permanently change the taste/smell of the buds (giving them a perfume-like smell and taste). This happens even if the ONA and cannabis buds never touch each other.
If ONA Gel is kept in your tent or grow room throughout the entire flowering stage, the effect can be overwhelming and buds may smell like ONA Gel or taste like perfume or chemicals after harvest.
ONA products do not need to actually touch buds to affect their smell and give them a bad, chemical or perfume-like taste
This is because the ONA gel actually binds to smells instead of covering them up. Smells are permantly changed when they come in contact with ONA products. The perfume smell seems to actually become “attached” to your buds, and there’s no way to get rid of it at that point, even after months of curing.
Ona products are great at covering up odors in your living spaces, but should never be placed near budding cannabis plants
Don’t use ONA products near your plants in the flowering stage unless you want buds that smell like perfume and taste like chemicals.
Febreeze too! Any type of “odor neutralizer” can have the same effect. Even if you never get any ON your plants, the buds can still be affected if they share the same air. Although ONA offers some of the strongest and most effective products on the market (and therefore ONA seems to have the greatest effect), you shouldn’t be using any other odor neutralizers anywhere near your grow room either.
What Exactly Is ONA Gel?
The ONA formulations have been around for a long time – initial development began over 25 years ago. The scientist who is credited with inventing the first forms of ONA gel noticed that when terpenes were released into the air, strong smells were reduced.
More development created formulations that not only masked smells, but permanently removed them from the air.
“AiR8” is the term to describe ONA gel when it’s used for industrial or commercial applications (for example to neutralize smells in sewer plants). The basic formulation is the same – AiR8 is used by big businesses, while ONA products are packaged and sold to individual consumers or small business who want to permanently remove smells.
According to Odorchem Manufacturing Corp., the people who make ONA: “This hydroscopic polymer has been saturated with a water-based formulation of active ingredients in order to slowly release into the air. AIR8 GEL is NOT a MASKING AGENT. It is a permanent solution for the treatment of numerous odors.” Learn More About The Science Behind ONA (aka AiR8)
Here are the 3 mechanisms used by ONA products to get rid of odors:
Absorption: retains the smell through absorption
Adsorption: collects and holds on the smell
Chemical Reaction (The “Pairs” Theory) — This is probably the most problematic part of ONA products for cannabis growers. The chemical reaction caused by ONA gel involves the permanent bonding of the odorous molecule (VOC) and the ONA active ingredients. This mechanism transforms the original smell from what it was into something new. As a result, the original odor disappears, to be replaced with a new molecule that is meant to smell like ONA gel.
How Cannabis Growers Can Properly Use ONA Gel
If you’re going to use ONA Gel to cover up smells that are being exhausted out a window, make sure the ONA gel is an actual part of the exhaust (air blows over ONA on the way out to neutralize the smells, so no ONA air ever comes in contact with your plants).
If you’re worried about smells in the home, it is recommended you keep ONA products in your living areas (or otherwise outside the grow room). For example. ONA gel can be placed in your living room or hallways to make sure the smell of cannabis does not leak into your living areas.
The main idea is to prevent ONA products from ever sharing air with your buds.
There Are Better Ways to Cover Up Smells!
If you can afford it (and have room), I definitely recommend installing a carbon scrubber as part of your exhaust system to neutralize smells as the hot air escapes out your exhaust hole. With a carbon scrubber, there’s zero worry about affecting the smell/taste of your buds.
Carbon scrubbers will pull scents out of the air, so exhaust air smells neutral, but carbon scrubbers don’t permanently alter smells the way that ONA products can. A carbon scrubber also lasts a lot longer than a single package of ONA gel.
