13 Classic Weed Strains That Changed Cannabis

Updated October 2026

Short answer: thirteen classic weed strains that still shape modern cannabis are OG Kush, Sour Diesel, Chemdawg, Northern Lights, White Widow, AK-47, Super Silver Haze, Super Skunk, Bubba Kush, Granddaddy Purple, Purple Haze, Headband and Thai. Their histories are part documentation, part oral tradition, so this guide separates well-sourced dates from the stories nobody can conclusively prove.

Modern menus are full of descendants, reinterpretations and names that borrow from these classics. That makes the history worth knowing—but it does not make every jar with the same strain name physically identical. Grower, phenotype, harvest and cure can change density, moisture and aroma. Use the grinding notes below as starting points and adjust to the flower in front of you.

For adults 21+ where cannabis is legal. Rules vary by state, so check your local law.

What "OG" actually means

Nobody knows for sure, and anyone who tells you otherwise is guessing loudly. The two popular theories:

• "Ocean Grown." A nod to Southern California coastal grows, where OG Kush became famous in the mid-'90s.
• "Original Gangster." Borrowed from hip-hop slang for someone established and respected.

What is documented: Leafly's OG Kush history places the strain in Florida in the early 1990s, with the cut arriving in Los Angeles around 1996. From there "OG" turned into a badge of honor, and now it's on more strain names than anyone can count. Today we use "OG strains" loosely to mean the classics: the foundational plants modern breeding is built on.

Quick comparison: the classics at a glance

Use the jar, not just the name. If the material is sticky or bridges a clean screen, try a coarser option. If the sift contains more visible plant particles than you want, try finer. The strain name alone cannot determine the ideal screen.

On a 4 piece, the screen influences what reaches the kief chamber; the teeth, load and number of turns do most of the work on the flower itself. Start with the installed standard screen. If a clean screen repeatedly bridges, try coarser. If the sift contains more visible plant particles than you prefer, try finer. The Upgrade Kit lets you compare all three openings in the correct size for your grinder.

The greatest classic weed strains of all time

1. OG Kush

The West Coast's foundation stone. Florida in the early '90s, L.A. by 1996, and then everywhere. Its exact parents are still argued about; Chemdawg, Lemon Thai and Hindu Kush are the usual suspects. The aroma is fuel, skunk and spice with pine and lemon, and people often describe the high as heavy and relaxing.

How to grind it: Break dense buds into smaller pieces, load loosely and use short turns. Start with the installed screen, then adjust only if the clean mesh bridges or the sift is coarser than you prefer. Full story in our OG Kush strain guide.

2. Chemdawg

The origin story is pure folklore with a paper trail: seeds found in what was thought to be Northern California bag weed at a Grateful Dead show in Colorado, grown out by a breeder known as Chemdog from 1991. It's widely credited as an ancestor of both OG Kush and Sour Diesel. Sharp diesel and chemical smell, the kind you notice from across a parking lot.

How to grind it: Use short turns and avoid packing resinous flower against the screen. If a clean standard screen repeatedly bridges, test the coarse option. Read more in our Chemdawg 91 deep dive.

3. Sour Diesel

East Coast royalty from the early '90s. Leafly lists it as Chemdawg x Super Skunk, though the full story (and which Chem cut was involved) is disputed among old-school growers. Pungent diesel with citrus; people often describe it as fast, energizing and cerebral, the classic daytime strain.

How to grind it: Start with the installed screen and use short turns, stopping when the texture suits your intended use. See the Sour Diesel strain guide.

4. Northern Lights

Afghani x Thai, likely born in the Pacific Northwest near Seattle and made famous in Holland after 1985 through Sensi Seeds. It's a parent of Super Silver Haze and Shiva Skunk. Sweet and spicy with pine; people often describe it as deeply relaxing, an end-of-night strain.

How to grind it: Break tight buds apart before loading, leave room for the teeth to work and adjust the screen only after judging a clean standard setup. The Northern Lights strain guide has the rest.

5. White Widow

The '90s Amsterdam icon. Bred by Shantibaba while at Green House Seeds from a Brazilian sativa and a South Indian indica, and it won the Cannabis Cup in 1995, according to its Wikipedia entry. The name comes from the white blanket of resin. Woody, earthy and floral; people often report an energetic, talkative buzz.

How to grind it: Use short turns on lighter buds. Start with the installed screen; try finer only if you prefer slower collection and fewer larger particles in the sift. More in our White Widow guide.

6. AK-47

Released by Serious Seeds in 1992, blending Colombian, Mexican, Thai and Afghani genetics. Per its Wikipedia page, it had racked up sixteen awards by 2020, including wins as both a "sativa" and an "indica," which is very on-brand for a strain whose name sounds aggressive and whose effects people describe as mellow. Sour, earthy and skunky.

How to grind it: Start with the installed screen and use short turns, checking the texture before turning again. Full profile: AK-47 strain guide.

7. Super Silver Haze

Green House Seeds crossed Skunk, Northern Lights and Haze and won the High Times Cannabis Cup three years running: 1997, 1998 and 1999. Bright citrus peel, herbal middle, incense on the exhale. People often describe it as uplifting and long-lasting.

How to grind it: Airier flower can reach the desired texture quickly, so use fewer turns and check before continuing. Read the Super Silver Haze guide.

8. Super Skunk

Skunk #1 x Afghani, a longtime Sensi Seeds catalog staple. Leafly lists it in Sour Diesel's family tree. It smells exactly like the name: skunk, earth, a weird hint of black licorice. People often describe it as a full-body relaxer.

How to grind it: Break dense flower apart, load loosely and watch whether the clean screen bridges before changing mesh size. Details in the Super Skunk strain guide.

9. Bubba Kush

Around 1996, an OG Kush plant pollinated an unknown indica that came from New Orleans, at least according to the most-told version of the story. Its genetics aren't certain, but its descendants are: Kush Mints and Wedding Cake both trace back here. Sweet hash, coffee and chocolate. People often save it for the end of the night.

How to grind it: Hand-break bulky buds first, load loosely and use short turns. More in our Bubba Kush strain guide.

10. Granddaddy Purple

Popularized in California in 2003 by Ken Estes. The commonly cited cross is Purple Urkle x Big Bud, though some sources list a Mendo Purps, Skunk and Afghani background instead. Deep purple buds, grape and berry nose, and people often describe it as relaxing without being a total knockout.

How to grind it: Break dense buds apart first and use short turns, adjusting only after you see how the actual batch behaves. Full profile: Granddaddy Purple guide.

11. Purple Haze

Named for (and popularized by) Jimi Hendrix's 1967 song. The commonly listed lineage is Purple Thai x Haze, and how far back the actual plant goes is murky. Sweet berry, earth and sharp spice; people often describe it as creative and energizing.

How to grind it: Airy flower usually needs fewer turns. Start with the installed screen; use a 2 piece if you prefer to keep everything together. Read the Purple Haze guide.

12. Headband

OG Kush x Sour Diesel, two legends in one plant. The name comes from the pressure people describe feeling around the crown of the head, like wearing a headband. Lemon and diesel with a creamy smoke; it's a parent of Paris OG and Pink Starburst.

How to grind it: Break dense flower apart, load loosely and use short turns. If a clean screen bridges repeatedly, test the coarse option. The Headband strain guide has more.

13. Thai stick

Less a strain than a legend. Thai landrace buds were tied around a bamboo stick, wrapped in fan leaves and bound with hemp string, a tradition from northeast Thailand. They reached the U.S. in the 1960s and '70s with surfers and Vietnam veterans, and the supply mostly dried up in the 1980s. Modern versions are often coated with concentrate or kief.

How to grind it: Pull the stick and string first (please don't grind bamboo). Break it up by hand; concentrate-coated pieces will gum a screen, so use a PRO 2 Piece Medium with short turns. Full story: the legendary Thai stick.

Gear for grinding the classics

Some batches of OG Kush, Bubba Kush and Headband are dense and sticky. Phoenician's machined cutting teeth, trapezoidal drop-through holes and short-turn threadless connection are designed to manage the grinding path without spiral threads to cross-thread. Resin can still collect on any contact surface, so regular cleaning matters.

PRO 4 Piece Medium
The everyday grinder for every strain on this list, with a swappable screen for kief.

FAQ

What is the most famous weed strain of all time?

OG Kush is the usual answer, since so many modern strains descend from it. White Widow, Northern Lights and Sour Diesel are right there too.

What does OG stand for in weed?

Nobody knows for sure. "Ocean Grown" and "Original Gangster" are the two main theories. Today it usually just means a classic or a descendant of OG Kush.

Are classic strains weaker than modern strains?

Many newer strains are bred for higher THC, but numbers vary a lot by grower and batch. A well-grown classic still holds its own.

How should I grind dense, sticky classics like OG Kush?

Break dense buds into smaller pieces, load the grinder loosely and use short back-and-forth turns. Start with the installed screen, then adjust only if the clean screen clogs quickly or the sift is coarser than you prefer.

The classics earned their spot. Give them a grinder that does them justice.
