Chronic Strain Info

Make your mark in modern marijuana history by cultivating the classic gene, Chronic. This is a legendary strain that’s been on the market since 1994, and for good reason; to this day, the genetic produces high-quality yields with premium effects that are well-balanced with almost equal Sativa and Indica traits.


When we say legend, we mean legend. Chronic is a triple-cross of three classic lineages: Northern Lights, Skunk, and AK-47. Serious Seeds takes their genetic game seriously, and re-vamped the phenotype in the 2000s with the addition of AK-47 to increase the sticky-icky nature of Chronic’s resin abundance.

Flowering Time

Even though the flowering time of Chronic may take 9-10 weeks to reach full maturity, rest assured that its end yields are well worth the wait!


With Chronic, you won’t lose out on quantity for quality, as its yields are just as impressive as its lineage and effects. The strain grows optimally either indoors or outdoors, adding to its versatility for growers. In any environment, you can expect to harvest pulls of 350-600g/m2 (1,14-1,9oz/ft2).


Chronic is a strain that can be enjoyed day or night due to its full-bodied and well-balanced effects. Recreational and medical users alike can benefit from its cerebral euphoric effects, with a side of soothing physical relaxation. The strain will have your mind feeling clear and focused as your spirit is happy and elated to take on any task. The strain’s effects are best for treating chronic pain, ADD, and appetite loss, so get ready for a case of the munchies, too!

THC Levels

Chronic is a mildly potent strain that can reach THC levels of 20%.

Smell And Taste

With a name like Chronic, you’d better believe the strain produces classic and pungent scents. Its sweet and skunky terpene profile has underlying notes of earthiness and pine – be sure to cure your yields properly so you don’t lose out on its versatile aromatics, which are slightly fruity and spicy in taste while puff, puff, passing.

Grow Tips

Chronic is a strain that’s fairly easy to cultivate for advanced growers, and of only medium difficulty for those just starting out. The plant maintains a moderate height for indoor or outdoor grows, which is easy to manage for shape plus highly discreet for neighbor purposes. You’ll also be thrilled with Chronic’s glow thanks to its ample coating of trichomes glistening from its dense, olive-green buds. Other tips for cultivating Chronic include:

  • Avoid topping for potential high stress to the plant.
  • The strain benefits from a semi-humid climate, with ideal temperatures of 72-80℉ (22-26℃).
  • With an ideal leaf to flower ratio that maximizes light exposure, pruning is unnecessary and trimming is simple.
