Cannabis use in Ancient China has a rich and diverse history. Likewise, so does hemp, which has long been grown for its wide range of uses. Experts believe that hemp seeds were being consumed for nutrition in Ancient China as far back as 6000 BC.

With such a longstanding tie to the cannabis plant, it seems fitting that modern-day breeders should return to 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 secrecy adds an air of mystery and intrigue to this already exciting and exotic strain.

Reportedly Ace Seeds bred the China Yunnan strain 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.

In terms of its potency, China Yunnan’s THC level tends to range between 15%-19%, which most should find 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 causes heightened sensory awareness, particularly to visual stimuli. However, these psychedelic-type effects are likely to be pretty mild. Still, it is essential to know that you might experience these 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 seem to fade away.

As time passes, you will start to feel drowsy and find it hard to keep your eyes open. Pretty soon afterward, you’ll likely 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.

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 keeping the temperature of your grow room at 25 degrees Celsius or 75 degrees Fahrenheit for the first four weeks of the flowering period. 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.

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 practice 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 grows during the vegetative stage, bend the new growths away from the plant’s center 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.

And it’s not just pain that this strain could help. 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 for 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. Doing so will give time for China Yunnan’s initial high to dissipate.

Also, by allowing enough time to pass before trying to go to sleep, you give China Yunnan’s indica effects time to take hold fully. When these soporific effects have you entirely in their grasp, you’ll likely drift off into a peaceful night’s sleep.

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.
