Critical strain guide
Critical is an indica-leaning hybrid of Afghani and Skunk #1, best known through Royal Queen Seeds. It's a sturdy, old-school strain with an earthy, woody smell and a calm, relaxed feel, and it's a close relative of Critical Mass.
Where does Critical come from?
Critical is a cross of Afghani and Skunk #1. The version most people know comes from Royal Queen Seeds, though several seed companies sell a strain under the same name, so not every Critical is the same plant.
That Afghani and Skunk #1 pairing is the same one behind Critical Mass, and the two names are often mixed up. Sources usually describe Critical as roughly 60% indica, and it's popular with growers for its quick flowering and heavy yields.
What does Critical smell and taste like?
Critical smells earthy and sweet, with woody, nutty notes and a darker, tarry edge some people notice. A few describe a fruity, lemon and apple aftertaste on the exhale.
Pinene tends to lead its published terpene results, followed by myrcene and terpinolene. Pinene brings the woody, foresty side and myrcene the earthier, softer base.
Critical effects: what people report
People most often describe Critical as relaxing and sleepy, a settled body feel that suits slower evenings. Others mention a happier, more talkative lift at first, so reports vary with the batch and the amount.
These are experiences people report, not promises. Dry mouth, dry eyes and dizziness are the most common complaints.
How strong is Critical?
Critical sits in the middle for potency. Listings commonly put it around 18% to 19% THC, with very little CBD, which is moderate next to many newer strains.
Even so, start small and give it time before having more. The numbers on your label matter more than the name, and our indica vs sativa guide explains why type labels only tell part of the story.
Buying Critical in Canada
Because Critical, Critical Mass and Critical Kush are all sold under similar names, read the label closely to see which one you have.
Check the THC and CBD numbers and the packaging date, since fresher flower keeps more of its earthy, sweet smell.
Critical vs Critical Mass
Critical Mass comes from the same Afghani and Skunk #1 pairing, and many people treat Critical as a newer seed-company take on it. In practice they're very close: both smell earthy and sweet, both lean relaxing, and both are grown for their big yields. Critical Mass is the older, better-known name, while Critical is the version you'll see most often from Royal Queen Seeds. If you can find either, the label's numbers will tell you more than the name.
