Before weed was legal — local dealers sold bud dubbed chronic.

The name chronic implied that the strain was so hard-hitting that it left you gasping for breath. However, it’s unlikely that you actually smoked real Chronic — one of the most heaviest-weight strains of all time.

If you’re ready to experience one of the most classic weed strains in the cannabis industry — it’s time to learn about Chronic. Below, you’ll discover all of Chronic’s incredible traits, growth characteristics, and where to buy real Chronic seeds online.

About the Chronic Strain


In the late 90s and early 2000s, cannabis breeders began to create epic hybrids by utilizing mind-blowing sativas and body-numbing indicas.

One of the leading breeders of the time was Serious Seeds. In the early 2000s, Serious Seeds began a new project that would result in one of the most iconic seeds of a generation.

By crossing Northern Lights, Skunk, and AK-47 — Chronic seeds were born. At this moment, the weed game would change forever as cultivators quickly realized the potential of hybridization.

Serious Seeds quickly realized that Chronic was on another level. From jaw-dropping frost to rip-roaring effects, the Chronic strain proved its worth.

Since its release, many cannabis enthusiasts have taken to calling top-shelf weed chronic. Whether you’ve experienced real Chronic or not — it’s time to grab some Chronic seeds and experience what generations of cannabis enthusiasts rave about.

As a final note, you may find different names for Chronic, such as Chronic OG, Cronic, and White Chronic. Therefore, always double-check that you are buying real Chronic seeds and not a fake cultivar!

Growing Chronic Seeds

If you’re ready to grow Chronic seeds — you need to understand what makes Chronic plants happy or sad.

In other words, it’s in your best interest to have an understanding of Chronic’s needs. As you mature as a grower, you’ll understand that each marijuana strain has various needs to produce top-shelf buds.

Below, we’ve detailed all of the Chronic strain’s growth traits. Furthermore, we’ve included insightful grow tips to ensure a heavy haul at the end of the season.

From grow difficulty to flowering time and everything in between — we have you covered from A-Z!

Grow Difficulty

The Chronic strain is easy to cultivate indoors or outdoors.

If you’re a beginner that wants to grow top-shelf buds — Chronic is your golden ticket. Furthermore, professional growers will enjoy Chronic’s stress-free growth and eye-popping bag appeal.

Remember, the Chronic strain tends to produce most of its yield on the apical bud. In other words, the top-most section of the plant will generate the most flowers.

Therefore, growers are advised to use support poles or netting to bolster the apical bud from collapsing on itself.

Lastly, if you choose to train your Chronic crop, the best methods are topping and FIM. However, Serious Seeds advises not to train Chronic if you don’t have to.

Optimal Growing Conditions and Climate

Overall, the Chronic strain enjoys warmth, moderate humidity, and abundant sunshine.

If you grow Chronic seeds outdoors, you must find a sunny location that receives little to no shade. Remember, the more sunlight — the bigger the buds!

However, be wary of mid-summer rainstorms. Overall, Chronic produces ridiculously dense buds, which attract mold and mildew when moist.

If you grow Chronic seeds indoors, you must maintain a temperature range of 77-86F. Although you won’t be penalized for going above or below these values, 77-86F is ideal.

Additionally, humidity must remain between 40-70% during the flowering stage. Furthermore, introducing CO2 into the grow tent will produce buds unlike anything you’ve seen before.

Lastly, indoor growers must ensure a fully operational ventilation system. By doing so, you’ll avoid issues such as overheating and overwhelming humidity.

Flowering Time

The Chronic strain flowers in 8-10-weeks.

However, the average flowering time of Chronic is 9-weeks. Although 9-weeks is by no means short — the results make up for the longer-than-usual wait.

Indoor growers may experience a faster turnaround period — especially those using hydroponics. However, all Chronic seeds produce various phenotypes, which may or may not harbor a fast-flowering trait.

As for outdoor growers, expect to harvest Chronic’s buds by the middle of October. If your region experiences sub-zero temperatures at the beginning of October, you may want to grow Chronic indoors.


The yield potential is one of the main selling points of the Chronic strain.

Overall, indoor cultivators may produce upwards of 600g/m2. When you consider most weed strains produce 450g/m2 — Chronic is clearly a heavy-yielding variety that shouldn’t be slept on.

If you grow Chronic seeds outdoors, you may harvest up to 600-grams per plant. If you’re wondering — 600-grams of top-shelf weed is a lot.

Ultimately, Chronic yields so much bud that you’ll need to throw a trimming party to get the job done in a timely manner.


The Chronic strain grows to a moderate height.

Overall, Chronic plants may reach 100-180cm in height. Therefore, indoor growers must provide a short vegetative period. Although training methods can be employed, we do not recommend using them on Chronic.

As for outdoor growers, the Chronic plant will grow to a medium height and produce strong and bushy stems. Come harvest time; you’ll find the majority of buds at the top of each Chronic plant.

Resistance to Pests and Diseases

The Chronic strain offers medium resistance to common pests and diseases.

Although Chronic can handle minor issues with gnats or aphids, things can spiral out of control once spider mites or bud rot enter the picture. Remember, your Chronic plants can only do so much on their own.

As a cannabis cultivator, it’s your job to ensure the safety of your plants. Besides, your overall yield potential depends on it. Therefore, it’s in your best interest to implement an IPM program to guard your Chronic crop.

The best practices to ensure the health of your Chronic plants are:

  • Remove the lowest growth (lollipop)
  • Add one oscillating fan per meter squared
  • Adequately space each plant
  • Keep your garden clean
  • Always wear clean clothes into the grow room
  • Apply organic neem oil during the vegetative stage
  • Inspect crop daily

Chronic Strain Description and Properties

The Appearance of Chronic Weed

One look at Chronic, and you’ll immediately know that you’re about to get rekt.

The flowers of Chronic are unbelievably frosty. Each bud is encased in ultra-sticky resin that seems almost surreal. Overall, you won’t be able to see much greenery under so many trichomes.

Once you dig through the frost, you’ll find lime green calyxes and electric orange pistils. Furthermore, each bud is dense and retains a fair bit of moisture to guard against dry weed.

Ultimately, the Chronic strain produces flowers that are a sight to be seen — and then smoked.

Dominant Cannabinoids Found in Chronic Buds

The dominant cannabinoid found in Chronic weed is THC.

Chronic flowers can contain 18-22% THC when grown with care. However, green thumbs may find higher concentrations of THC when dialed in.

Furthermore, beginners must be aware of Chronic’s hard-hitting strength. If your THC tolerance is low — you may feel Chronic’s potency after a single hit.

Whether you’re a newbie or not, you should always consume Chronic slowly.

Once you indulge, buckle up — your taste buds are in for a treat. The flavor of Chronic is loaded with spicy musk, sweet herbs, and sour citrus.

The three primary terpenes found in Chronic weed are limonene, caryophyllene, and pinene.

The limonene and caryophyllene provide ample levels of spice and dank citrus. However, the pinene comes through with elegant tones of pine needles and fresh herbal bliss.

Effects of the Chronic Strain

Before you indulge in Chronic, remember — it’s named chronic for a reason.

As you take a massive puff from your vaporizer or blunt, the smoke from Chronic immediately tightens your chest. Soon after exhaling, your lungs expand, and the THC diffuses into your blood — catapulting your mind into outer space.

The initial effects are strictly mental and produce a surging euphoria, endless laughter, creativity, and motivation. As the mental effects settle, Chronic provides a solid body stone that encapsulates your body in a warm blanket of bliss.
