Harle-Tsu: A Dominant Force for Health and Well-Being
Well-regarded for its minimal psychoactive effects and high CBD content, Harle-Tsu (also called Harlequin Tsunami) is a popular choice among medical cannabis users seeking relief without the typical euphoria associated with THC-heavy strains. It was originally developed by Southern Humboldt Seed Collective and has since won first place for the best CBD flower at the Emerald Cup (2014).
With a CBD:THC ratio often exceeding 20:1, this strain ensures a mellow, clear-headed experience. In short, If you're seeking a cannabis strain with loads of CBD and almost no THC, Harle-Tsu is an option worth considering.
Genetic Background of Harle-Tsu: Two CBD Titans Collide
Harle-Tsu's genetic lineage stems from two famous CBD-rich strains: Harlequin and Sour Tsunami. As its name suggests, Harle-Tsu combines "Harle" from Harlequin and "Tsu" from Sour Tsunami, putting on full display the influence of its parent strains. This unique genetic history is a critical factor in Harle-Tsu's reputation as a go-to strain for those seeking the potential benefits of CBD without the intoxicating effects of THC.
Harlequin is a sativa-dominant hybrid celebrated for its unique CBD:THC ratio, which often reaches or exceeds 5:2. With a diverse terpene profile, Harlequin offers a range of aromas and flavours often described as earthy, sweet, and musky.
Another sativa-dominant hybrid, Tsunami is characterised by a high CBD content and low THC levels, creating a balanced cannabinoid ratio. This results in a mild and lucid experience, imparting limited psychoactive effects. Tsunami is also praised for its earthy, woody, and citrusy flavours.
Aroma and Flavour of Harle-Tsu: Subtle But Enjoyable
Harle-Tsu offers a well-balanced aroma and flavour profile that caters to those seeking subtlety in their cannabis experience. This strain presents an olfactory journey defined by nuanced notes of earthiness and woodiness, occasionally laced with subtle hints of sweetness. These aromatic qualities can be attributed to the presence of terpenes such as myrcene and pinene.
Regarding taste, Harle-Tsu faithfully mirrors its aromatic essence, delivering a gentle herbal flavour accompanied by pronounced earthy undertones, courtesy of myrcene. For the discerning palate, there may be faint traces of citrus or pine, thanks to the abundance of pinene and terpinolene.
This harmonious and understated fragrance and flavour profile makes Harle-Tsu an attractive option for individuals who prefer a more refined and less overpowering cannabis experience.
Potency and Effects of Harle-Tsu: Made for Medical Users
Harle-Tsu is celebrated for its unique cannabinoid profile, which sees CBD dominate over THC. As such, it appeals chiefly to those who prioritise the medicinal aspects of cannabis and wish to avoid the typical high associated with other strains.
With THC levels typically measuring at less than 1%, this strain imparts essentially no psychoactive effects, ensuring a clear-headed experience. Because of this, Harle-Tsu is not a common choice among recreational cannabis enthusiasts but is rather favoured by individuals seeking the therapeutic benefits of CBD.
The dominant feature of Harle-Tsu is its high CBD content, often exceeding 20%, making it a prime choice for medical cannabis users. This strain is commonly used for its potential to alleviate symptoms of physical and mental discomfort.
Given Harle-Tsu’s negligible THC content, side effects are unlikely when enjoying this strain. However, in some people, headaches, dizziness, and dry eyes can occur.
Growing Harle-Tsu: For Indoor and Outdoor Growers
Harle-Tsu is suitable for both indoor and outdoor cultivation, but it thrives in a controlled indoor environment. This is especially important if you want to maximise the plant's CBD:THC ratio, as sticking to an indoor grow-op will help you carefully manage environmental factors.
Indoor Growing Tips
Harle-Tsu tends to exhibit a tall and lanky growth pattern, and therefore, a trellis or ScrOG (screen of green) setup is recommended to support the plants and optimise light exposure. Harle-Tsu is relatively resistant to common pests and diseases, which can simplify the cultivation process. However, to ensure optimal CBD development, it's important to maintain a consistent lighting schedule and control environmental factors such as temperature and humidity. Growers should harvest this strain when the CBD content peaks (after roughly eight weeks of flowering), observing the plant's trichomes for the optimal window.
Outdoor Growing Tips
To prevent waterlogging, ensure that the chosen spot provides well-drained soil. Planting in early spring when the threat of frost has passed is advisable, and plants should be spaced well to allow for good air circulation and light penetration. Additionally, Harle-Tsu can be susceptible to adverse weather conditions, so having a plan for protection during heavy rain or strong winds can be beneficial. Outdoor harvesting is typically done in early to mid-October.
Harle-Tsu: A CBD Sensation
With its high CBD content and only trace levels of THC, Harle-Tsu caters to individuals seeking therapeutic benefits without the pronounced psychoactive effects typically associated with THC-heavy strains. Its subtle aroma and flavour profile also make it a reliable choice for those who value a milder cannabis experience. Finally, Harle-Tsu's versatility in both indoor and outdoor grow-ops offers options to growers willing to give the proper care and attention.
