Big Perm strain guide
Big Perm is a gassy hybrid from the Permanent Marker family, but it isn't one single strain. Several breeders have released different crosses under the name, so what you get depends on who grew it. People describe fuel, berry and pepper, with an upbeat start and a heavy finish.
Where does Big Perm come from?
Most versions of Big Perm trace back to Permanent Marker, which is where the "Perm" comes from. Beyond that, the sources don't agree, because different breeders made different crosses.
One strain database lists LA Family Farms' version as a Permanent Marker backcross, Fire Bros.' as Pure Kush and Permanent Marker, and Floraganix's as Permanent Chimera and Scarface. Another database also mentions a Permanent Marker and Lemon Cherry Sherbert version. With no single agreed lineage, the best way to know yours is to check the producer.
What does Big Perm smell and taste like?
Gas and fuel lead in most descriptions, with diesel, grape peel, cracked pepper and creamy citrus behind them. One strain database's flavour tags lean sweeter: berry, sweet and butter. That mix makes sense for a family built around Permanent Marker's funky, sweet profile.
One strain database lists limonene and caryophyllene as dominant, but only for the Fire Bros. version, so other cuts may differ.
Big Perm effects: what people report
Reviews describe a mood-lifting, energetic and creative start, then heavy body relaxation as time goes on. Some reviewers say it gets strongly sedating after a couple of hours. One strain database notes its effects data is still limited, with only a couple of reviews.
These are experiences people report, not promises. How it feels depends on which version you have, how much you have and your own tolerance.
How strong is Big Perm?
Published figures put Big Perm at about 24% to 27% THC, with little CBD. Since several versions share the name, your batch could fall outside that range.
Start small and give it time, especially since reviewers say the heavier side shows up later. Your label's THC and CBD numbers are what count, and our guide to reading cannabis labels can help.
Buying Big Perm in Canada
With several crosses sold as Big Perm, the producer's name on the label is the best clue to which one you're getting. Expect smell and feel to vary between brands.
Check the THC and CBD numbers and the packaging date, since fresher flower keeps more of that gassy smell.
Big Perm vs Permanent Marker
Permanent Marker is the strain nearly every Big Perm builds on. Permanent Marker is known for a loud, sweet, soapy and gassy smell with a balanced feel. Big Perm versions tend to push the fuel and pepper harder, and reviews describe a heavier, more sedating finish. If you want the original funk, start with Permanent Marker. If you like it gassier and heavier, try Big Perm.
