Cannabis use in Ancient China has a rich and diverse history. Experts believe that hemp seeds were being consumed for nutrition in Ancient China as far back as 6000 BC.

In Ancient China, we can trace the cultivation of hemp to approximately 2800 BC. Hemp was mainly cultivated for its strong and durable fibers, which had many uses. According to Narconon, the first-ever recorded use of cannabis for medicinal purposes in China dates back to 2727 BC. While excavating the graves of shamans in China and Siberia, archaeologists discovered burned cannabis seeds. These ancient burial sites date back to around 500 BC.

With such a longstanding tie to the cannabis plant, it seems fitting that modern-day breeders should return to the place where cannabis was first used. Well, that’s precisely what cannabis breeders Ace Seeds have done. They traveled to the Southwestern Chinese province of Yunnan to work with the best South Asian sativa and indica landrace strains they could find. While there, they developed a new strain, which they respectfully and appropriately named after its place of origin.

Read on to learn more about the China Yunnan strain.

What Is the China Yunnan Strain?

The exact lineage of the China Yunnan strain has reportedly been deliberately kept secret by Ace Seeds. This adds an air of mystery and intrigue to this already exciting and exotic strain. What we know, and what we can infer from the strain’s name, is that it has been bred using a South Asian sativa variety, and a South Asian indica landrace. The resulting China Yunnan strain is a heavily indica-dominant hybrid with an 80:20 indica to sativa ratio.

China Yunnan’s THC level tends to range between 13%-19%, which most people should find pretty tolerable.


While China Yunnan’s effects are overwhelmingly indica in their latter stages, its initial effects are typically sativa in nature. Its high is euphoric and uplifting, without being too overpowering. Some China Yunnan consumers say that this strain also causes heightened sensory awareness, particularly to visual stimuli. However, these psychedelic-type effects are likely to be pretty mild. Still, though, it is essential to know that you might experience these types of effects before consuming this strain.

As its sativa effects begin to wear off, China Yunnan’s indica effects come more to the fore. A feeling of deep relaxation and calmness washes over you as this strain’s indica effects take hold. In this deeply relaxed state, any aches or pains that may have been bothering you tend to fade away.

As time passes, you will start to feel drowsy, and you’ll find it hard to keep your eyes open. Pretty soon afterward, you will begin to drift off into a peaceful and restful night’s sleep. The nature of China Yunnan’s effects makes this strain much more suitable for evening rather than daytime use. Its pleasant and uplifting high mellows and fades into a deep body-melt relaxation, and ultimately, sleepiness.

We ask you, is there a better way for a cannabis lover to relax and unwind after a long and busy day?


The China Yunnan strain has inherited the sweet and woody aromas of the sativa plants of South Asia. It also has a distinctive smell that has been likened to cheese, as well as some mild, fruity notes.


Taste-wise, China Yunnan’s cheesy and earthy flavors are more prominent on the inhale. You can taste this strain’s fruitier flavors on the exhale.


A mature China Yunnan plant is said to have a look similar to a hash plant. While this plant remains pretty compact, it does produce reasonably broad leaves. A China Yunnan plant has an almost columnar structure with a distinctively large main bud.

China Yunnan’s buds are dark green, and they are heavily coated in a generous layer of resinous trichomes. This plant also has beautiful purplish hues and long, thin, orange-colored pistils.

China Yunnan Strain Grow Info

While a China Yunnan plant can be grown indoors or outdoors, it is better suited to an indoor grow room. This way, you can carefully control the temperature that your plants are exposed to. Experts recommend that for the first four weeks of the flowering period, you keep the temperature of your grow room at 25 degrees Celsius or 75 degrees Fahrenheit. You should then reduce the temperature down to 20 degrees Celsius/70 degrees Fahrenheit for the remainder of the flowering period.

Experienced China Yunnan growers recommend topping this plant early in the vegetative stage. China Yunnan growers also recommend the use of Low-Stress Training (LST).

LST encourages new node growth. This should cause the plant to thicken up and become bushier. By increasing the number of new node growths, you are also increasing the potential yield that each plant will produce.

How to Perform Low-Stress Training

The three-finger technique is best for performing LST. First, place your index and middle finger on the plant’s stem about an inch from the top.

With your thumb behind the stem, gently ease the plant’s stem over your thumb using your two fingers. Continue to work your way down the stem until the plant is bent over to one side.

Try to keep the plant’s leaves out of the soil as it can be harmful to them. To keep the stems bent over, use some string or a thin cable as an anchor. Wrap around the top of the plant’s stem and tie it to the side of the air pot to keep it secure.

By using the three-finger technique, you are less likely to damage the plant’s stem. Your China Yunnan plant should respond to the LST by growing up towards the light from its bent-over position.

Over the next few days, you will start to see the newly formed node growth. As the plant continues to grow during the vegetative stage, bend the new growths away from the center of the plant and the light.

It is essential only to perform LST every second day at most. You should allow the plant to rest for at least 24 hours after performing LST so that it can recover and produce new nodes.

The flowering period for a China Yunnan plant is between eight to nine weeks when it is you grow it indoors. If you are growing this plant outdoors, then it will be ready for harvesting around late September or early October.

The indoor yield is relatively moderate at around ten to twelve ounces per square meter. Outdoor growers are looking at a return of approximately twelve ounces per plant.

THC Content – Highest Test

The highest THC level in a China Yunnan sample is around 19%. Most experienced cannabis consumers should find this THC level to be pretty manageable.

CBD Content – Highest Test

The highest CBD level recorded in a China Yunnan sample was as high as 3%.

Medical Benefits of the China Yunnan Strain

With such an impressively high CBD level, you can see why this strain is so popular with medicinal marijuana consumers. But its purported medical benefits aren’t limited solely to its CBD content.

China Yunnan’s moderate THC content also offers mood-enhancing benefits to consumers. Its pleasant, uplifting high could potentially make this strain suitable for treating mood disorders like depression and anxiety.

Many medicinal marijuana users say that China Yunnan is also very effective for pain relief. Its indica genetics instill a deep body-melt feeling, during which users say that pain just fades away. Some of the painful conditions that the China Yunnan strain may relieve include chronic arthritis, muscular pain, as well as headaches.

And it’s not just pain that this strain could be useful for. China Yunnan is also becoming increasingly popular with cannabis consumers with insomnia due to its soporific effects. However, if you intend to use China Yunnan to treat insomnia, be mindful that its initial effects are sativa in nature.

Therefore, it is advisable to consume this strain a few hours before you plan on retiring for the night. This will give time for the China Yunnan’s initial high to dissipate. Also, by allowing enough time to pass before trying to go to sleep, you are giving China Yunnan’s indica effects time to take hold fully. When these soporific effects have you entirely in their grasp, you should feel so deeply relaxed that you will drift off into a peaceful night’s sleep.

Possible Side Effects of the China Yunnan Strain

The most common side effects associated with the China Yunnan strain are cottonmouth and dry eyes. However, as already mentioned, you may also experience heightened sensory perception.

These psychedelic-type effects may be a little bit disconcerting for a novice cannabis consumer. However, more experienced cannabis lovers will probably find these effects more stimulating than overwhelming.

Final Thoughts on the China Yunnan Strain

We think that you will agree that Ace Seeds’ trip to Yunnan Province was worth it. The China Yunnan strain that they developed there is an outstanding strain that both recreational and medicinal consumers will enjoy.

While China Yunnan’s genetics are predominantly indica, its sativa effects are conspicuous in its early effects. China Yunnan’s initial high is euphoric and uplifting but not overwhelming. Some consumers of this strain say that they experienced heightened sensory perception after consuming this strain. It is essential to be aware of this before consuming this strain.
