Full Spectrum Extract (FSE)
Full spectrum extract (FSE) is a minimally refined cannabis concentrate that preserves the plant's complete chemical profile — cannabinoids, terpenes, and flavonoids together, where distillate isolates a single compound. The result tastes like the strain actually grew. At VanCity Labs, FSE is extracted in-house from our own BC cannabis.
About Full Spectrum Extract
Most refinement in cannabis is subtraction: distillation strips a plant down to one compound at maximum purity. FSE goes the other way. It's extracted gently and refined minimally, so the finished concentrate keeps the strain's full chemical fingerprint — a quality FSE can carry hundreds of distinct compounds, where a distillate carries fewer than twenty. That's why FSE is the connoisseur's format: it doesn't just test like the strain, it tastes and smells like it.
FSE typically presents in two fractions. HTFSE — high-terpene full spectrum extract — is the saucy, aromatic liquid, often 13–40% terpenes. HCFSE — high-cannabinoid — is the crystalline fraction, sugar or diamond textures rich in THCa. Many jars combine both, which is exactly what our diamonds and sauce line is. Everything here is extracted in-house from our own BC flower, strain-labelled, from the same lab behind the whole concentrates wall.
How FSE Compares
Against distillate: distillate wins on the THC number (85–95%) but arrives nearly flavourless, with terpenes often added back afterward; FSE carries the strain's own terpenes at far higher levels, trading a few potency points for character. Against live resin: the terms overlap more than they differ — premium FSE is usually made from fresh-frozen flower too. "Live resin" describes the input (fresh-frozen); "full spectrum" describes the output (nothing stripped away). Many users find the fuller profile a richer experience than any isolated compound — a preference worth testing yourself rather than a settled rule. If you want the strain, whole, this is the format built for it.
How VanCity Labs Makes Its FSE
Preserving a full profile means gentle handling at every step: our FSE comes from our own BC flower, extracted cold in our in-house lab and finished without the aggressive refinement that strips character. We've run this as a vertically integrated operation for over 30 years — the same team grows, extracts, and finishes, with no middlemen and no third-party brands. Every jar is Lab Grade finished and labelled with its tested potency. Orders ship in Stealth Packaging across Canada by tracked courier — discreet by default.
How to Dab FSE
Treat FSE like the terpene product it is: low-temperature dabs on a rig or e-rig keep the profile intact — high heat torches exactly what you paid the premium for. If your jar has separated into sauce and crystals, stir gently or take a bit of both per dab for the full effect. Store airtight, cool, and dark; refrigerate what you won't finish soon. Compare the crystalline end of the spectrum at THCA diamonds, the fresh-frozen flavour route at live resin, or the solventless craft at live hash rosin.
Frequently Asked Questions
What does "full spectrum" mean?
That the extract preserves the plant's complete chemical profile — cannabinoids, terpenes, and flavonoids together — instead of isolating one compound. A quality FSE carries hundreds of compounds; a distillate carries fewer than twenty.
What's the difference between HTFSE and HCFSE?
Two fractions of the same extract. HTFSE is the high-terpene liquid — saucy, aromatic, often 13–40% terpenes. HCFSE is the high-cannabinoid crystalline fraction — sugar and diamond textures rich in THCa. Many jars combine both.
Is FSE stronger than distillate?
On the raw THC number, usually not — distillate runs 85–95%. But FSE keeps the strain's full terpene and cannabinoid profile that distillation strips away, and many users find the fuller profile a richer experience than the higher number alone.
Is FSE the same as live resin?
Close cousins. Most premium FSE is made from fresh-frozen flower, just like live resin. "Live resin" names the input (fresh-frozen plant); "full spectrum" names the output (a complete, unstripped profile). A jar can honestly be both.
Why does FSE taste more like the actual strain?
Because nothing was removed. The terpenes and minor compounds that give a strain its specific smell and taste survive the gentle extraction, so the jar carries the flower's real fingerprint instead of a reconstructed flavour.
What is diamonds and sauce?
The combined presentation of FSE's two fractions — THCa crystals (the HCFSE side) sitting in high-terpene sauce (the HTFSE side). See our THCA diamonds page for the full breakdown of that format.
How should I dab FSE?
Low temperature, always — the terpene profile is the whole point, and high heat burns it off instantly. If the jar has separated, take a little crystal and a little sauce per dab. Store airtight, cool, and dark.
How are FSE orders delivered?
All orders ship in Stealth Packaging across Canada by tracked courier — discreet, unmarked outer packaging by default. Details live on our shipping policy page; more questions on our FAQ. Cannabis is sold to adults 19 and older in BC.
