Farm Gas (Cannabis flos Aurora): lineage from Sour Diesel and GMO, and the profile depends on the source
One position from Aurora with an established lineage. Two Polish services describe the terpene composition of this strain differently, and we report the THC content as a range, not as a single number.
| Strain Card | Farm Gas |
|---|---|
| Producers | Aurora (1 pharmacy position) |
| Medical Brand | the same as the producer |
| Alternative Names | none |
| Category by Sources | hybrid / indica (sources inconsistent) |
| Leading Terpene | limonene |
| Other Terpenes | humulene caryophyllene myrcene nerolidol |
| Lineage | established Sour Diesel × Gmo |
| Source Consistency | divergent (2 sources) |
- Who supplies. Only Aurora, so there is nothing to compare versions with, and a supply break means no availability of this strain, not another version of it.
- Profile. Limonene leads, alongside humulene, caryophyllene, myrcene, and nerolidol. We do not provide percentage shares because sources calculate them against different totals.
- Origin. Established lineage, parents are Sour Diesel and Gmo.
- What is missing. Two sources describe the profile differently, so the further part of the set is disputed, not established.
Where does Farm Gas come from and who cultivated it?
Farm Gas was cultivated by the Canadian Aurora in collaboration with North 40 Cannabis, and its parents are Sour Diesel and GMO. The lineage is established, as confirmed by two independent descriptions: the industry service StratCann when granting the breeder rights to the strain and the database describing the genetics of this cross.
Both parents have their own positions in Polish pharmacies, so the origin can be traced back more than one generation. Sour Diesel appears in our graph without established parents, as available descriptions of its origin contradict each other and none can be pointed out as certain. GMO has documented parents, Chemdawg and Girl Scout Cookies, and its phenotype has been described as garlicky.
The name says less than it seems. The fuel component is also listed for Modified Gas from a completely different producer, and these two strains do not share a common parent or breeder. The repeated word comes from a naming convention describing the aroma, not from kinship. Therefore, we read the lineage from the breeder’s description, not from the sound of the trade name. The breeder’s rights were granted to Farm Gas along with the second strain of the same application, Driftwood Diesel, which is not listed at all in Poland.
Which producers supply Farm Gas to Polish pharmacies?
One. Farm Gas is supplied to Polish pharmacies exclusively as an Aurora position, a Canadian producer that has ten strains in our list. Therefore, there is no alternative version of the same name from another supplier, and any comparison of series concerns the same producer and the same documentation.
| Producer | Raw Material Origin | THC Content According to Source | What Distinguishes This Position |
|---|---|---|---|
| Aurora | Canada, producer’s own cultivation | 24.3-29.7% | the only position of this name in the list, marked in the strain database as widely available |
Hemp flower is a pharmaceutical raw material dispensed by prescription in the Rpw category, so positions from the list are not chosen independently at the pharmacy counter. Separately from pharmaceutical raw material, we maintain a category of over-the-counter flower, in which none of these positions stands.
Aurora supplies ten names to Poland, and Farm Gas is among them as one of two with lineage tracing back to the diesel line. The producer cultivates in its own facilities, which means that the series documentation comes from one entity, not from an intermediary packaging raw material purchased elsewhere.
The composition of supplies changes over time and this is not a flaw in the list. The permit for raw material admission expires after five years, the wholesaler may be out of stock for several weeks, and the producer can withdraw a series after testing results. Therefore, the current state is maintained exclusively in the list of strains available in Polish pharmacies, updated separately from pages describing individual names.
What does Farm Gas smell and taste like?
- humulene humulene
- caryophyllene caryophyllene
- limonene limonene (leading in the pharmacy list)
- myrcene myrcene
- nerolidol nerolidol
Descriptions indicate four notes: citrus, fruity, fuel, and peppery. The first impression can be sour citrus, followed by a heavy tone associated with spilled fuel, and in the background remains a sharpness similar to freshly ground pepper. The trade name refers precisely to this second note.
The aroma from the description is not a measurement. The scent notes in strain databases come from the producer’s material or from reports of people who opened the raw material, not from sensory analysis conducted according to protocol. Two series of the same name can smell differently because the aroma depends on the harvest time, the drying method, and how long the package has been in the wholesaler.
The terpene composition attributed to this position includes humulene, caryophyllene, limonene, myrcene, and nerolidol, although not all these names appear in both sources. The fuel tone is usually attributed not to a single compound but to a combination of volatile sulfur compounds with the terpene background, and none of the available databases for Farm Gas measure these first ones. We do not provide percentage shares with names because both databases omit the denominator, and their total values do not add up to one hundred. Nerolidol is the only one mentioned in both descriptions, so it is the most reliable reference point here, although it does not account for the fuel tone.
How long does it take for Farm Gas to take effect and how long does the effect last?
This depends on the route of administration, not the strain name. No measurements of concentrations over time have been published for Farm Gas, so the ranges below describe the behavior of hemp flower when vaporized and after ingestion and apply equally to any other position from the list.
The route of administration determines the course more than the strain itself, and the ranges below describe it, not the cultivar, because pharmacokinetic studies for a single cultivar have not been published.
| Vaporization | After Ingestion | |
|---|---|---|
| First Feelings | after a few minutes | from half an hour to two |
| Onset | another dozen to thirty minutes | slowly, over several hours |
| Total Duration | within two to four hours | after six, sometimes eight hours |
| Typical Error | none | taking a dose after thirty minutes, which gives both doses at once |
The difference between these two routes is often confused with differences between strains. Anyone comparing Farm Gas with another position, but once grinding it for vaporization and once preparing it for oral use, is actually comparing two routes of administration. A conclusion about the strain itself can only be drawn from such a comparison when the route and dose are identical on both sides.
What is known and what is not known about the effects of Farm Gas?
It is known what terpene composition two Polish services attribute to this strain, and it is known that both descriptions differ from each other. However, nothing is known about the effects of the strain itself on humans: no clinical studies on a single cultivar have been conducted or published, and available works concern isolated terpenes.
Both sources describe the same position of Aurora, yet they differ in composition. The service budcare.pl lists five terpenes: humulene, caryophyllene, limonene, myrcene, and nerolidol. The service medweed.pl provides only nerolidol for this strain, so the four names from the first list are where the second source is silent. The discrepancy also extends to genetics, as the first description calls Farm Gas an indica strain, while the second calls it a hybrid.
The terpene indicated as leading here is limonene, so we gather evidence for it.
| Study | Model and Route of Administration | What Was Demonstrated |
|---|---|---|
| do Vale TG et al., 2002 Phytomedicine PMID:12587690 |
rodent (mouse, intraperitoneal administration) | Limonene administered intraperitoneally in mice showed muscle relaxant effects (rota-rod test) from a dose of 50 mg/kg and prolonged sleep induced by pentobarbital at a dose of 200 mg/kg (about 2.6 times); in the elevated plus maze test, already at a dose of 5 mg/kg, it reduced the number of entries into the open arms, which the authors described as an anxiogenic effect, not anxiolytic. |
| Fakhri S et al., 2025 Behavioural Pharmacology PMID:40622197 |
rodent (rat and mouse) | Limonene reduced paw swelling induced by carrageenan in rats and pain responses in the formalin test in mice; the effect was linked to the l-arginine/nitric oxide/cGMP/KATP channel pathway and involvement of opioid and benzodiazepine receptors. |
Separately, it should be noted what these studies did not show. The anxiolytic effect of limonene in humans has not been demonstrated. It has also not been shown that isolated limonene has anxiolytic effects in animals; the only available data from the elevated plus maze test showed in mice an effect opposite to what was expected, reducing the number of entries into the open arms even at a low dose. Everything else circulating about this strain comes from the producer’s material or from reports of people using the raw material, and such a source does not replace research.
What adverse effects have been reported after Farm Gas?
None under this name. Reports go to supervision with the batch number of a specific product, not with the strain name, so there is simply no separate statistics for Farm Gas. The following description concerns hemp flower as a group of raw materials, and that is all that can be said honestly about it.
Reports of adverse effects are collected for a medicinal product with a batch number, not for the strain name, so the following concerns hemp flower as a group of raw materials. The most commonly reported effects are dry mouth, red eyes, and increased heart rate. Dizziness upon rapid standing, daytime drowsiness, and transient worsening of short-term memory are less frequently described, as well as anxiety increasing with dosage. A separate issue is medications taken concurrently, especially sedatives and those affecting coagulation: their assessment requires knowledge of the entire list of preparations, not just the description of the plant. We do not provide the frequency of these symptoms numerically, as public compilations for hemp flower in Poland do not separate them by individual products.
Two things from this list are worth relating to Farm Gas itself. The declared content of psychoactive substances is high for this position compared to the list, and the increase in anxiety has been described as dose-dependent, not dependent on the name on the package. The reaction can also be different upon first contact with the raw material than after several weeks of use, which is determined by the attending physician, not the strain description.
What do the boiling temperatures of Farm Gas terpenes say about vaporizer settings?
Less than popular tables suggest. Among the names attributed to this strain, limonene boils at 177.8 degrees Celsius, myrcene at 166.8, and caryophyllene only at 257.5. For humulene and nerolidol, none of the collected sources provide a measurement made at atmospheric pressure, so their thresholds cannot be compared with the others.
The boiling point is not a threshold, below which nothing evaporates. A compound also transitions to vapor at a lower temperature, just more slowly, as vapor pressure increases with temperature in an exponential manner. For this reason, a table linking a terpene with a single number describes a chemical property, not a device setting. Limonene actually has two values in the collected records because measurements come from different studies. The record for nerolidol mentions 275-277 degrees, but without specified pressure, and the only record for humulene was made at a pressure reduced to three millimeters of mercury, so none of them can be placed in the same column as the others.
Additionally, the number on the vaporizer display is not the temperature of the flower. The setting describes the heating element or the air entering the chamber, and the material is cooled by airflow when inhaling and heats unevenly. The difference between one value and another exists, but has not been publicly measured, so we do not provide it numerically. Separately, we explain why temperature tables from different sources contradict each other.
Which strains from Polish pharmacies are related to Farm Gas?
| Strain | Common Parent | Leading Terpene | Producers |
|---|---|---|---|
| Chemango Kush | Gmo | caryophyllene | Aurora |
| Sourdough | Sour Diesel | limonene | Aurora |
Two. Chemango Kush shares a parent with it, GMO, and Sourdough shares Sour Diesel. Both come from the same producer, so kinship goes hand in hand with common raw material origin, not just a shared word in the trade name. There is no third such position in the list.
Chemango Kush has a four-parent lineage and among its components is GMO, the same one whose phenotype has been described as garlicky. However, the rest of the origin goes in a different direction, through OG Kush and Wedding Cake, so the similarity ends at one ancestor.
Sourdough shares with Farm Gas the second parent, namely Sour Diesel, and the other half of the lineage comes from Wedding Cake. An interesting fact about the graph is that both related names meet Farm Gas from two different sides: one through the diesel line, the other through GMO. However, they are connected by Wedding Cake, which is not present in the lineage of Farm Gas at all.
Neither Sour Diesel nor GMO disappear from the list as separate positions, as both names have their own suppliers in Polish pharmacies, different from Aurora. Therefore, the comparison of parent to offspring is feasible, although it concerns raw material from two different cultivations and two independent documentations.
Frequently Asked Questions about Farm Gas
Is Farm Gas an indica strain?
It depends on the source. One description calls it an indica strain, the other a hybrid, and the lineage from Sour Diesel and GMO does not resolve this definitively. The division into indica and sativa does not have a counterpart in the chemical composition of the raw material.
How many producers supply Farm Gas to Polish pharmacies?
One, the Canadian Aurora. There is no second position with this name in the list, so the comparison of series always concerns the same supplier and the same documentation.
What THC content is reported for Farm Gas?
A range of 24.3-29.7%, as the producer’s declaration has a tolerance of ten percent of the value, and providing a single number would be false precision. Only one source provides the tolerance for this position.
Does limonene from Farm Gas have anxiolytic effects?
This has not been demonstrated. Available studies concern isolated limonene administered to rodents, and in the elevated plus maze test, the effect turned out to be the opposite of what was expected.
Does the smell of Farm Gas say anything about its potency?
No. The intensity of the aroma depends on the terpene content, and these are measured separately from the content of psychoactive substances. A strong fuel tone can be confused with potency, although one is not related to the other.
Why does the availability of Farm Gas change from month to month?
Because the list depends on permits and supplies. The permit expires after five years, a series can be withdrawn after testing results, and the wholesaler can be out of stock for several weeks. The current state is maintained exclusively in the strain list.
