Blue Cheese Cannabis Seeds by Expert Seeds
Blue Cheese is a feminised cannabis seed from Expert Seeds that crosses two legendary genetics — UK Cheese and Blueberry — into an almost pure indica (90%) built for evening relaxation and resin-heavy harvests. If you've ever wanted a strain that genuinely smells like a cheese board with a punnet of blueberries sitting next to it, this is the one. Available in packs of 3 or 5 seeds.
Pack Sizes
| Pack | Seeds | SKU |
|---|---|---|
| Small | 3 feminised seeds | CSEX0009 |
| Standard | 5 feminised seeds | CSEX0052 |
Go with 5 if you want room to select the best phenotype for a mother plant. The 3-pack works fine if you're running a single tent and just want to fill it without leftovers.
Blue Cheese Genetics: Cheese Meets Blueberry
Blue Cheese seeds carry the pungent, skunky backbone of UK Cheese — arguably Britain's most famous cannabis clone — crossed with DJ Short's Blueberry, a strain that's been winning cups since the early 2000s. The result is a 90% indica / 10% sativa hybrid that leans heavily into physical relaxation while keeping a touch of mental warmth. Expert Seeds stabilised this cross to produce consistent phenotypes with dense, resinous flower clusters and a terpene profile that genuinely lives up to the name.
We've seen a lot of "cheese" strains pass through the catalogue over the years. What sets this Expert Seeds version apart is the Blueberry influence — it rounds off the sharp, almost acrid cheese funk with a sweeter, berry undertone that makes the smoke noticeably smoother. The 20% THC content puts it in the upper-mid range: strong enough to deliver a proper body stone, not so strong that one extra puff sends you to the shadow area.
Blue Cheese Flavour and Aroma Profile
The nose on Blue Cheese is unmistakable — open the jar and you get hit with that sharp, aged cheddar funk that Cheese genetics are famous for, followed immediately by a softer, almost jammy blueberry sweetness underneath. It's not subtle. Your carbon filter earns its keep with this one.
On the inhale, the cheese dominates — think mature Stilton rather than mild Gouda. The exhale is where the Blueberry parent shows up: a fruity, slightly floral finish that lingers on the palate. According to research on cannabis terpenes, strains with this kind of complex terpene profile often contain notable levels of myrcene, caryophyllene, and linalool. A 2021 review in Frontiers in Psychiatry noted that linalool — a terpene also found in lavender — has been examined for its potential calming properties in preclinical models (Franco et al., 2021, PMC8426550).
Honest note: if you're growing this in a shared building, invest in proper odour control. We've had customers underestimate Cheese crosses before. The smell starts in mid-flower and only gets louder.
Growing Blue Cheese Seeds Indoors and Outdoors
Blue Cheese feminised seeds produce compact, bushy indica plants that respond well to both indoor and outdoor cultivation. Here's what Expert Seeds lists for performance specs, and what we'd add from experience.
| Specification | Detail |
|---|---|
| Seed Bank | Expert Seeds |
| Genetics | UK Cheese x Blueberry |
| Type | Feminised photoperiod |
| Indica / Sativa | 90% Indica / 10% Sativa |
| THC Content | 20% |
| Indoor Flowering Time | 60 days |
| Indoor Yield | Approximately 500 g/m² |
| Outdoor Harvest | Mid to late September |
| Outdoor Yield | 600–900 g per plant |
| Resin Production | High — large, dense flower clusters |
| BHO Suitability | Excellent (high cannabinoid and resin content) |
A 60-day flowering time is quick for an indica that yields 500 g/m² indoors. That's roughly 8.5 weeks from flip to chop — about a week faster than many comparable indica-dominant strains. Outdoors, the 600–900 gram per plant figure assumes a decent growing season and a plant that's been vegged properly through spring and summer. In Northern European climates, aim for a mid-September harvest; don't push it into October or you're gambling with mould on those dense buds.
Blue Cheese Indoor Grow Tips
Blue Cheese's compact indica structure makes it a strong candidate for SOG (Sea of Green) setups. The plants stay short and bushy, which means you can pack more into a smaller footprint without losing light penetration. Here's how we'd approach it:
- Germinate your Blue Cheese seeds using the paper towel method or directly in a starter plug. Taproots typically emerge within 24–72 hours.
- Transplant seedlings into their final containers once the first set of true leaves appears. For SOG, 6.5–11 litre pots work well.
- Veg for 2–3 weeks under 18/6 light. Blue Cheese doesn't need a long veg — the indica genetics fill out quickly.
- Flip to 12/12 and watch for pre-flowers within the first week. Stretch is minimal with this strain, typically 30–50% height increase.
- Support the main colas from week 5 onwards. The dense flower clusters get heavy and can snap branches without stakes or a trellis net.
- Maintain relative humidity below 50% during the final two weeks of flowering. Those thick, resinous buds are magnets for botrytis if airflow is poor.
- Flush for the final 7–10 days with plain pH-adjusted water to improve the flavour of the finished product.
- Harvest around day 60 when trichomes show a mix of milky white and 10–15% amber — this gives you the full-body indica effect Blue Cheese is known for.
One thing to watch: Blue Cheese can be a hungry feeder during mid-flower. If you see the lower fan leaves yellowing faster than expected around week 4–5, bump up your nitrogen slightly. It's not a fussy plant overall, but it does eat more than something like a standard Skunk.
Blue Cheese for BHO and Concentrate Production
Expert Seeds specifically flags Blue Cheese as a great strain for BHO (butane hash oil) production, and the numbers back that up. With 20% THC packed into large, dense flower clusters that are — in Expert Seeds' own words — "abound in resin and filled to the brim with cannabinoids," you're looking at excellent starting material for extracts. The combination of high resin output and a complex terpene profile means your concentrates retain that distinctive cheese-and-berry flavour rather than tasting like generic dab.
If you're growing specifically for extraction, consider running the plants slightly past peak maturity — an extra 3–5 days lets the trichome heads swell further. You'll sacrifice a bit of THC potency in exchange for a larger overall yield of resin glands. According to WebMD's cannabis strain database, Blue Cheese also contains approximately 2% CBG (cannabigerol) — a secondary cannabinoid that contributes to a broader entourage effect in full-spectrum extracts.
Blue Cheese Effects: What to Expect
This is a late-evening strain, full stop. The 90% indica genetics deliver a deeply relaxing body effect that starts in the shoulders and works its way down. You'll feel the tension in your muscles unwind within the first 10–15 minutes. The Blueberry side adds a gentle mental warmth — not stimulating, just comfortable. Don't plan on doing anything productive afterwards.
According to a study published in the Journal of Cannabis Research examining patient perceptions, indica-dominant strains are consistently associated with more sedative and physically relaxing effects compared to sativa-dominant varieties (Pearce et al., 2014, PMC6275121). That aligns with what we'd expect from a 90/10 indica split at 20% THC.
The honest limitation: if you're looking for something creative or social, Blue Cheese isn't it. This strain pins you to the sofa. That's either exactly what you want or exactly what you don't — there's no middle ground. For daytime use, you'd be better off with something like a Haze or Sativa-leaning hybrid.
Complete your grow setup with a carbon filter — Blue Cheese's pungent aroma demands proper odour control. If you're after a contrasting daytime strain to complement Blue Cheese's evening character, have a look at our Amnesia Haze seeds for something on the opposite end of the spectrum.
Why Blue Cheese Seeds Deserve a Spot in Your Garden
We've carried a lot of Cheese crosses over the years, and the Expert Seeds Blue Cheese keeps coming back for three reasons: the 60-day flowering time is genuinely fast for this level of yield, the resin production is outstanding for extract makers, and the flavour profile is one of those rare cases where the name actually matches what you taste.
The 500 g/m² indoor yield puts it in line with strains that take 9–10 weeks to finish, but you're getting there a week sooner. Outdoors, 600–900 grams per plant is serious weight — and the dense bud structure means less trimming time per gram than a stretchy sativa. For anyone running a perpetual harvest, that fast turnaround adds up to an extra cycle per year compared to a 70-day strain.
The genetics are stable, too. Expert Seeds has been working with this Cheese x Blueberry cross long enough that phenotype variation is minimal. You're not going to get one plant that smells like cheese and another that smells like lawn clippings. They're consistent — which matters if you're dialling in a grow room or producing extracts where flavour consistency is everything.
Frequently Asked Questions
What does Blue Cheese taste like?
Exactly what the name suggests — a sharp, aged cheese flavour on the inhale with a sweeter blueberry finish on the exhale. The cheese note is dominant, closer to mature Stilton than anything mild. The Blueberry genetics smooth it out and add a fruity, slightly floral aftertaste.
How long does Blue Cheese take to flower?
Expert Seeds lists 60 days of flowering time indoors. That's roughly 8.5 weeks from the light flip, which is fast for an indica yielding 500 g/m². Outdoors, harvest falls in mid to late September in the Northern Hemisphere.
Is Blue Cheese good for making concentrates?
Yes — Expert Seeds specifically recommends Blue Cheese for BHO production. The dense buds are packed with resin and contain 20% THC, making them excellent starting material. The terpene profile also carries through well into extracts, so your concentrates retain that cheese-and-berry character.
What yield can I expect from Blue Cheese seeds?
Indoors, roughly 500 g/m² under standard grow-room conditions. Outdoors, Expert Seeds quotes 600–900 grams per plant, assuming a full growing season and adequate veg time. SOG setups can push indoor yields higher by maximising canopy coverage.
Is Blue Cheese hard to grow?
Not particularly. The compact indica structure keeps things manageable, and the 60-day flowering time means less time for things to go wrong. The main thing to watch is humidity in late flower — those dense buds can develop mould if airflow and humidity aren't controlled. Keep RH below 50% in the final two weeks.
Does Blue Cheese smell a lot during flowering?
Absolutely. Cheese genetics are some of the most pungent strains around, and the Blueberry cross doesn't tone it down — it just adds another layer. A carbon filter is not optional if you're growing indoors or in any space where odour matters.
What is the THC content of Blue Cheese?
Expert Seeds lists Blue Cheese at 20% THC. According to WebMD's strain database, it also contains approximately 2% CBG. That's a solid cannabinoid profile for both smoking and extraction purposes.
