This exotic pure strain, a probable link between indicas and traditional sativas from South Asia, shows characteristics of both spectra of cannabis.

On the one hand, it grows with a robust and compact structure, developing beautiful broad leaves and an indica hash plant appearance. Its flowers mature quickly, with abundant resin production and penetrating aromas. On the other hand, it has a touch of Asian sativa, which can be felt at the beginning of the effect, in some of its woody aromas, and in the morphology of some taller, more branched plants with narrow leaves.

It is a genetic line that maintains good vigour at the population level and offers productive specimens, preferring stable temperatures, a dry environment and a large amount of nutrients to achieve its best yields. And although production suffers with lower final temperatures, the resin quality improves greatly in colder conditions.

Most plants produce high THC and low CBD chemotypes, with potent, warm, pleasant and relaxing effects. Occasionally you can also find plants rich in both THC and CBD, not so psychoactive in effect, but offering excellent properties to combat anxiety, depression as well as mental and emotional stress.

Robust, with short internodes. Indoors with a short growth period, it produces columnar plants with large central buds. Outdoors and with more growth, its develops a well-branched, ball-shaped structure.

Ace Seeds found 3 main terpene profiles in this variety, which can appear combined in each individual example to a greater or lesser extent. The first is the creamiest and most sweet & sour, reminiscent of the blend of aromas from a Chinese restaurant. The second profile is darker, organic, with incense, and hashish. The first two groups produce denser terpene profiles and are more prevalent in indica expressions. The third, also very organic, but with more woody and floral influence, is more commonly found in expressions tending towards the more sativa side.

Cheerful effects, expansive and visual at the onset. Warm, pleasant and relaxing in its development and final phase.

It mainly contains the following monoterpenes: big amounts of alpha pinene, beta myrcene, limonene and beta pinene, and lower amounts of fenchol, camphene, borneol, ocimene and phytol. Sesquiterpenes: mainly beta-caryophyllene, guaiol and humulene, and traces of bisabolol, caryophyllene oxide and nerolidol.

Adapts exceptionally well to indoor grows with artificial light. In order to obtain the best indoor results, Ace Seeds recommend warm temperatures (of around 25ºC) during the growing and the 4 first weeks of flowering. In the last month, lower down moisture and temperature to 20ªC during the rest of the flowering stage.

Outdoors, Ace Seeds recommend warm, dry climates. Excellent results throughout Southern Europe.

Genetic analyses carried out on China Yunnan show that this variety has a unique genotype, with moderate genetic variability, showing direct kinship with Ace Seeds China Yunnan hybrids: Orient Express and Kali China.

Excellent landrace indica to cross with sativa strains, since it easily produces hybrids with enormous yields, fast flowering and interesting aromas and effects.

Ace Seeds recommend moderate-high levels of fertilisers throughout the growing cycle, respecting the dry cycles of the substrate, and avoiding excessively long periods of wetness (particularly in the more indica-leaning specimens).
