Critical Mass strain guide
Critical Mass is an old-school, indica-leaning cross of Afghani and Skunk #1 from Mr. Nice Seed Bank. It's known for an earthy, skunky smell and buds so heavy they can snap their own branches. People mostly describe it as relaxed and sleepy.
Where does Critical Mass come from?
Critical Mass comes from Mr. Nice Seed Bank in the Netherlands, the seed company Shantibaba (Scott Blakey) ran with Nevil Schoenmakers, named after the smuggler Howard Marks. Its cross is Afghani with Skunk #1, two of the most important building blocks in modern cannabis.
Some seed sellers describe it as a reworked version of the older Big Bud line, which fits its reputation for huge yields. The name is usually explained by that weight: the buds can get so dense that branches break under them. Growers also note it is prone to mould for the same reason.
What does Critical Mass smell and taste like?
Expect an earthy, skunky jar with wood and a little spice. Many people also pick up citrus or lemon peel on top, and some describe a sweet, honey-like or hashy note.
The published terpene profile lists myrcene first, then caryophyllene and limonene. Myrcene brings the earthy, musky base, caryophyllene a peppery bite and limonene the citrus. The taste is usually skunky and sweet with an earthy finish.
Critical Mass effects: what people report
Reports lean strongly toward relaxed and sleepy, with a tingly, heavy body feel. At smaller amounts some people describe a happy, mellow lift first. At larger amounts couch-lock and hunger come up often.
These are experiences people report, not promises. How it feels depends on the product, how much you have and your own tolerance. Dry mouth and dry eyes are the most common complaints, and some people mention feeling anxious or dizzy.
How strong is Critical Mass?
Strain listings put Critical Mass at about 18% to 22% THC, moderate by today's standards. CBD is less clear: most listings give little, while one puts it near 5%. Some products sold under the name test far higher in THC or CBD, which usually reflects a concentrate or a different cut.
Start small and give it time before having more. The numbers on your own label are the ones that count, and our guide to reading cannabis labels explains how to read them.
Buying Critical Mass in Canada
Critical Mass is sometimes sold simply as Critical, and several related strains use the word in their names, such as Critical Kush. Check the label so you know which one you're getting.
You might find it as dried flower, pre-rolls or hash. Look at the THC and CBD numbers, which can vary a lot for this strain, and the packaging date.
Critical Mass vs Afghani
Afghani is one of Critical Mass's parents, a landrace indica from the mountains of Afghanistan. Both are earthy and heavy, but Afghani is the purer, hashier one, with woody, piney notes, while Critical Mass adds the pungent skunk and citrus of its Skunk #1 side. Critical Mass also tends to list a little higher in THC. If you want the classic, earthy original, try Afghani. If you like a skunkier jar, go with Critical Mass.
