Critical XXL Strain Info

Critical XXL represents a new touch on the famous Critical genetics. Meticulously bred in Spain by Herbies Seeds, this 35% Sativa/65% Indica hybrid delivers a supreme high and offers exceptional yields that will make countless growers very, very satisfied.

Genetics

This strain’s lineage includes the all-time classic Skunk #1 as well as Afghani and Critical Mass genes, which are responsible for its potency and massive yields. Skunk #1 is known for its heavy, stoney-headed high coupled with deep body relaxation. Make no mistake: these legendary traits manifest themselves in Critical XXL, too.

Flowering Time

You can plant your Critical XXL seeds outside and inside, but we recommend growing indoors. In this case, you can expect a flowering time of 50 to 55 days.

Yields

If you’re growing indoors, you can expect higher than average yields of 500-600 grams per square meter (1.6-2 oz/ft²) and 1300-1600 grams (46-56 oz) per plant outdoors.

Effects

Critical XXL is very powerful and is best suited for nighttime smoking, although you can use it for quiet relaxation earlier in the day. Due to its high THC content and practically no CBD, this strain delivers a deep and peaceful body high with mostly Indica effects.

THC Levels

The potency of Critical XXL’s high is a stand-out feature due to the exceptionally high THC levels ranging from 24 to 27%.

Smell and Taste

Critical XXL sports a strong spicy smell with lemon notes, so you’ll be sure to have some delicious smoke sessions! This strain’s terpene profile is dominated by myrcene – one of the most common terpenes found in cannabis – that gives weed an earthy scent and taste.

Grow Tips

This strain thrives in any environment, but you might want to give her ample space since she’ll reach a medium height. Indoor-grown plants can reach from 100 to 120 cm (3’2-3’9), while outdoors, they can grow to 120-150 cm (3’9-4’9) in height. Critical XXL will impress cannabis enthusiasts because with this girl, you’ll get solid frost-covered buds in a very short time.

  • Critical XXL enjoys an 18/6 light schedule while in veg. When she’s ready to flower, switch her to a 12/12 schedule.
  • Start your seeds in at least 10-liter pots to give the roots enough space for growth.
  • The plants could do with topping and SoG to maximize their already generous yields.

      the seeds popped very fast. Moved ‘em to soil, and they shot up without issues. Plants stayed manageable and stacked weight quick. High is potent, leans sleepy.

      First time grower here and this strain made me look like a pro 😂 They said go for autos, but I thought I’d give this beauty a try! Followed the tips from Herbies—18/6 light schedule in veg, flipped to 12/12, and boom! Plants stayed compact (around 3.5ft) but stacked dense, frosty buds like crazy. Did light LST—yields were stupid good. Only hiccup? The smell during flowering was LOUD (citrusy-spicy, but my carbon filter saved me)
      This sh*t hits HARD. Happy vibes at first, then total couch-lock. Tastes like lemons and earth, burns smooth. One joint and you’re done for the night.
      10/10 would grow again, smoke that’s worth the hype. Herbies nailed it with this one 🙌

      Solid strain, reliable. Grew like a dream - sturdy, didn’t fuss over minor temp swings, and pumped out dense, sticky buds. Smoke is heavy indica vibes, perfect for evenings. Not the fanciest terps, but it gets the job done.

      Honestly, I grabbed these seeds on a whim figured they’d be just another "XXL" hype strain, plus never tried growing Herbies own weeds before (though been buying from them for a while now). Now I wish I tried them sooner.
      The plants took off like rockets in veg, stacking nodes tight without much fuss. Kept ‘em under LED with a light feed schedule, and they barely blinked at my occasional neglect. Flowering was where they really shined - dense, greasy colas that reeked of citrus and diesel. Amazing yield!
      The smoke caught me off guard too. Expected a generic heavy indica knock-out, but it’s got a clear-headed lift before the deep body melt kicks in. Smooth burn, heavy expansion, and the terps carry through in the taste—rare for high-yielders.
      Think I’ll be running these again. If you want a no-BS strain that overdelivers, Critical XXL’s your ticket.

      one of 5 didn't sprout. I texted Herbie, they offered me a a nice replacement.
      the rest is now on progress, so far looks good
