Cannabidiol, better known as CBD, has been making tremendous waves in the medical community. The hemp industry could be worth roughly the same as the legal marijuana industry in a few years. The hemp cause has been greatly aided by the Hemp Farming Act of 2018, which was made law as part of the Farm Bill of the same year.

However, you don’t have to seek out hemp if you want a CBD hit. Strains such as Harle-Tsu have been specifically bred with a high CBD content in mind. Keep reading to find out more about this increasingly popular marijuana strain.

What is Harle-Tsu?

Harle-Tsu is a slightly indica-dominant (60:40) hybrid that was developed by the Southern Humboldt Seed Collective. It is a cross of Sour Tsunami and Harlequin.

The result is a form of marijuana that is exceptionally high in CBD. You may even receive a Harle-Tsu sample, which contains 38.78% CBD, although most samples will range between 20-24% CBD. One of the features of Harle-Tsu is the minimal THC content, which clocks in at below 1%. With a 20:1 ratio of CBD to THC, there is no chance of getting high from this strain.

First and foremost, you will NOT feel a psychoactive high when using Harle-Tsu.

However, perhaps you can swap your evening glass of wine for this strain? It may provide you with a sense of complete relaxation all over your body. The good news is that Harle-Tsu is not known to cause couch-lock.

Users also report feeling extremely happy when they use this strain. If you are feeling a little down in the dumps, a few hits of Harle-Tsu might boost your mood. One of the great things about Harle-Tsu is that it seems to read the needs of your body and mind. If you are tired, Harle-Tsu can relax you to the point where you drift into a deep and satisfying sleep.

However, if you are feeling a bit flat or need a pick me up, Harle-Tsu may provide ample rejuvenation. Best of all, the exceedingly low THC content means you shouldn’t get caught out by a drug test either.


Even a single whiff of Harle-Tsu will probably help you relax for a moment! The spicy odors offer a scent of pine, pepper, and earth. These aromas fill your senses to the point that you’ll feel like you’re taking a walk in a forest.


After you smell Harle-Tsu, you may expect it to have the same spicy and earthy taste. However, it is surprisingly sweet. There are also hints of citrus and pepper that sit nicely on your palette.


A Harle-Tsu plant has a pale green appearance, with fewer hairs and crystals than you would see on a high-THC strain. Harle-Tsu’s buds are fluffy and elongated and are almost grape-shaped in structure.

Harle-Tsu Grow Information

Sadly, growing information is hard to come by for Harle-Tsu. What is known is that if you are growing it indoors, you need to keep humidity levels in check.


If the foliage becomes too dense, make sure you trim it before mold and fungi start to form. Harle-Tsu is a strain that handles heat reasonably well. However, it is advisable to try to keep the maximum temperature to 80 degrees Fahrenheit or thereabouts.

When grown indoors, Harle-Tsu should take 8-9 weeks to flower, and it provides a relatively high yield. If you decide to grow it outdoors, make sure it isn’t exposed to humidity levels of above 50% during the flowering stage.

THC Content – Highest Test

As already mentioned, Southern Humboldt Seed Collective have specifically bred this strain to have a very low THC content. While the highest recorded THC content for this strain isn’t specified, it typically will contain less than 1% THC.

CBD Content – Highest Test

The Harle-Tsu strain has one of the highest average CBD contents out there. Most Harle-Tsu strains will have a CBD content in the 20-24% range. However, this strain’s CBD content can be considerably higher than this range. The highest known CBD content recorded in a Harle-Tsu sample is believed to have been an incredible 38.78%.

Medical Benefits of Harle-Tsu

Harle-Tsu has become one of the most highly sought-after medical marijuana strains. It is exceedingly rich in terpenes, and each terpene is believed to have its own specific medical benefit. Here is a quick list of these terpenes and what they can potentially treat:

  • Myrcene: Depression, insomnia, and muscle tension
  • Pinene: Fatigue
  • Humulene: Pain and inflammation
  • Terpinolene: Stress and insomnia
  • Ocimene: Has antibacterial and antiviral properties
  • B-Caryophyllene: Inflammation and gastrointestinal issues

It is the combination of numerous terpenes and CBD that provides Harle-Tsu with its purported medicinal qualities. Even though Harle-Tsu has minimal THC, it is still classified as a Schedule I substance, like every other marijuana strain.

This is an unfortunate situation, because Harle-Tsu, and other low-THC, high-CBD strains, may have enormous medical potential. Well, that is what the hundreds of studies that outline CBD’s benefits appear to indicate anyway.

As far as adults are concerned, Harle-Tsu is best used for stress or strained muscles. As you probably know, to your cost, whenever there is pain, inflammation is usually not far behind. Fortunately, Harle-Tsu may potentially help with inflammation and thereby facilitate a smoother and less painful recovery.

Possible Negative Side Effects of Harle-Tsu

As Harle-Tsu has a very low THC content, it is unlikely to exacerbate anxiety or heighten feelings of paranoia. In rare cases, you may experience dizziness and headaches.

Harle-Tsu is a smooth smoke. There is no real fear of having a coughing fit; however, it can result in dry mouth. You can easily avoid this by carrying a bottle of water with you and drinking before and after using Harle-Tsu.

Final Thoughts on Harle-Tsu Marijuana Strain

Harle-Tsu is one of the most relaxing smokes that you are likely to find. Sadly, even though its THC content is scarcely higher than that of industrial hemp, it remains federally illegal. It is also prohibited in the 17 states that have yet to legalize medicinal marijuana.

If you live in a state where medical marijuana is legal, you may be interested in trying Harle-Tsu. One of its benefits is that it potentially could help you to feel relaxed and upbeat without getting you high. Its significant CBD and terpene content may also provide you with other medical benefits matched by few other marijuana strains.
