Ace Seeds Nepal Jam Breeders Pack Standard – Semi Regolari.
FAST FLOWERING NEPALESE HYBRID, WITH A WARM AND HAPPY EFFECT, AND GOOD RESISTANCE AGAINST COLD AND RAIN. NOW AVAILABLE IN ALL ITS GENETIC DIVERSITY FOR BREEDING.
The Nepalese is a strong and compact highland sativa with short flowering and excellent resistance against mold and cold. Its dense and resinous flowers produce first class hash.
The Nepalese was crossed with a touch of Jamaican’85 to add vigor, yield, bluish colors and the classic positive Jamaican effect to the final hybrid, whilst maintaining the original compact nepalese behavior.
Excellent sativa for rainy and cold climates, and for indoor growing.
At ACE Seeds, we have done an intense stabilization work with Nepal Jam since 2014.
The turning point in this plant improvement project happened when we found an elite Nepalese dominant Nepal Jam F6 parental plant, highly worked and refined, of very fast flowering, which stood out above the rest of his sisters for having more fragrant terpenes, higher resin production, for its beautiful purple pigmentation and for its refined, warm and pleasant effect that made it stand out over the rest of its generation.
This Nepal F6 elite mother has been the main parental plant we have used to breed the best current Nepal Jam versions (both regular and feminized), as well as the best feminized Nepal Jam hybrids we have created to date and which have been released as a new limited editions since 2019.
The only downside of this elite F6 parental is its low production and lesser vigor, which is why we focused on finding more vigorous and higher yielding F6 males (from the same Nepalese dominant phenotype) with which to pollinate her and thus produce the following F7 and F8 generations. These new generations keep in a more stable way the best traits of elite F6 mother, and at the same time they improve her vigor and yield in a remarkable way, despite the strong endogamy in the breeding process.
Description of the different Nepal Jam standard lines included in this Breeders Pack:
– Elite F6 bx1: Backcross of the Nepal Jam F6 elite mother with her most vigorous, productive and aromatic sons. It is the most faithful line to the juicy terpenes, gleaming resins and the most desired effects of the Nepal Jam F6 elite mother, but with a moderate vigor and yield due to the inbreeding produced by this type of backcrossed breeding. It is therefore a very suitable line to find very stabilized parental plants with the best qualities of the elite F6 mother already fixed, with which to make more predictable outcrosses with other strains.
– F7 phenos with greater Jamaican influence: Although the recent breeding improvement that has been done over Nepal Jam is based mainly on the refinement of the Nepalese phenotype, in this Breeders Pack we also wanted to include lines with greater Jamaican influence to offer a broader range of possibilities within the genotype of this strain. The phenotypes with stronger Jamaican influence are characterized by being taller, more branched, less columnar and of thinner stems. They also have a slightly longer flowering time. The terpene profiles of these Jamaican expressions are woodier and less intense than the Nepalese phenos. They also produce less resin although their effects are more cerebral and energetic, with a personality closer to the Central American landrace sativas.
– F8 Nepalese phenos: Latest generation refined Nepalese expressions with the best qualities of the F6 elite mother (beautiful purple pigmentation, high resin production, sweet and organic penetrating terpenes, and the best warm, meditative and expansive effects), but significantly improving her vigor and yield. This is be the most suitable line to continue with the inbreeding of this strain beyond F8 generation, as well as to produce the most vigorous, productive and round Nepal Jam hybrids, in terms of quality of terpenes, resins and effects.

Terpene profile It contains the following monoterpenes: mainly beta myrcene in very high amounts, followed by traces of beta pinene, camphene, alpha pinene and linalool. Sesquiterpenes: mainly nerolidol, followed by smaller amounts of beta-caryophyllene and traces of guaiol.
Growing Tips Nepal Jam has acquired a surprising resistance against cold, rain and fungus. It produces excellent results, flowering even on foggy or icy days (in conditions where other varieties would easily die or rot).
It has been grown in a great variety of climates: warm or cold, dry or wet, including northern countries from Central and Eastern Europe.
Genetic analyses performed at Phylos laboratories show that Nepal Jam has a unique genotype and low genetic variability. Due to its stability, adaptability and resistance, we highly recommend Nepal Jam for breeding projects, and to develop fast flowering hybrids of warm and expansive effects.
We recommend moderate levels of nutrients for the whole cycle.
