N13 Kush Feminized

N13 Kush Feminized

N13 Kush Feminized is a compact and hardy indica that produces significant harvests. Hailing from an impressive heritage of Mr Nice G13 x Hash Plant x Nicole Kush, this 90% indica combines the best attributes of all of its parents.

Flowering Stage: 63 days

Total time, seed to harvest: 84 days

Final yield: 107 grams

THC content: 19.98%

This powerful, compact plant is favoured by amateur and commercial growers alike for its high-yielding harvests and impressively potent buds. N13 Kush Feminized is also known for its short flowering period of around 55-65 days. However, despite their rapid growth, these plants still offer prodigious harvests.

N13 Kush’s indica traits keep the plant compact and bushy, and its relatively small size makes them an excellent choice for outdoor and indoor growers. It is a hardy and resilient strain that can flourish in Mediterranean climates.

N13 Kush develops a large central cola covered in resin glands with plenty of leafy side shoots. Large, dense buds typically form around the nodes and main stem rather than lateral branches.

Our N13 Kush Feminized was grown indoors in a 220 x 180 centimetre cultivation room and elevated on a table for easy access. The room was illuminated with a single 600-watt Phillips GreenPower high-pressure sodium light. Plants were hand-watered daily throughout the growing cycle, and fans were used to ensure constant airflow. 

So, let’s take a closer look at each step as we raised our N13 Kush from seedling to harvest.

Germination & seedling

Our N13 Kush Feminized seed was sprouted in a propagation cube. Once roots had protruded through the sides, our 4 cm seedling was transplanted in a 3-litre pot of BAC Lavasoil mix. Our seedling was then placed 80 cm below the grow light

Our plant’s cotyledons had already emerged at this early stage and were looking relatively healthy. Two bright green, rounded leaves were already moving aside for the plant’s first true leaves.

We refrained from watering our N13 Kush until the third day to allow the roots to establish in their new medium. We pH-adjusted the water to 6.2 and added a root stimulant, bringing its electrical conductivity (EC) to 0.8. 

During week one, we also introduced the predatory mite, hypoaspis miles, into our grow room. These minuscule predators feast on any fungus gnat and thrip pupae that may be living in the medium. This process was repeated once more during week three.


Our N13 Kush received 18 hours of light and 6 hours of darkness throughout vegetation. The temperature fluctuated between 26°C during the day and 22°at night. The relative humidity (RH) was held at 65%. 

By the end of the second week, our N13 Kush had more than doubled in size and reached had nine centimetres. Following the production of cotyledons, she began producing broad fingered leaves. At the end of week two, she had developed multiple nodes with short internodal spacing, a clear indication of her indica characteristics.

BioGrow nutrients were supplemented into our nutrient solution during week three, bringing the EC to 1.4. Our N13 Kush had developed many sets of broad, lime green fan leaves. Her internodal spacing remained compact, and axillary shoots developed from each node. Our plant reached a height of 19 cm by the end of the week.


At the beginning of week four, knowing that she would stretch significantly during the first weeks of flowering, we changed our light’s photoperiod to 12 hours on, 12 hours off to initiate flowering. We stopped supplementing rooting hormone and BioGrow, and added BioFlower, bringing the solution’s EC to 1.6. Our N13 Kush Feminized seemed to enjoy her new diet and began stretching immediately.

Throughout flowering, the relative humidity of our grow room was lowered to 45%, and a sulphur burner was used during the evenings to decrease powdery mildew development.

We also hung sachets of Amblyseius Cucumeris and Amblyseius Californicus to consume any thrips larvae and two-spotted spider mites in our medium.

By the end of the week, our N13 Kush stretched to 32 centimetres and consumed 400 ml of water per day. The apical meristem had thickened substantially and looked capable of holding the high yielding harvest we expected. Many small shoots protruded from the nodes, and axillary shoots developed small shoots of their own.

Week five saw the apical bud develop an array of pistils, and N13 Kush’s short internodal spacing made for dense foliage near the top. Calyxes had also begun to form amidst the bouquets of white pistils while the thick, rich green fan leaves continued to soak up light from our 600W HPS. By the week’s end, our plant had grown to 60 centimetres.

We began week six with a one-day flush of the root zone with pH adjusted tap water, which was repeated at the start of the eighth week. The week also saw the continued development of many preflowers all over the plant. The small mounds of calyxes that had developed began pushing out many more white pistils at the tops of all shoots.

The plant’s internodal spacing was relatively short, though the sativa genetics played a role in its appearance. It doesn’t appear as bushy as most indica plants, though the rich green fan leaves possess the typical wide blades of an indica. By the end of the week, our N13 Kush had grown 12 centimetres.

The apical stem had swollen significantly throughout week seven, and the apical bud was growing into a large cola. As the plant continued to focus on bud development, the leaves’ petioles began to develop rich purple streaks, an indication of the plant’s Kush genetics. Our N13 Kush had grown a remarkable 19 centimetres to an astounding 91 centimetres, and was consuming 1000 ml of water daily.

Week eight brought the end of the stretch, and our N13 Kush had reached 95 centimetres by the week’s end. The main cola had swollen significantly and required support to keep the plant from falling over. Golfball-sized buds were developing at lower nodes and on the tips of side shoots.

Throughout week nine, a noticeable layer of resin glands developed on the surface of the swollen calyxes, and an abundance of white pistils protruded from the bud sites. Fan leaves had begun to fade to light hues of lime green and yellow, and she was still consuming 1000 ml of water daily.

The pistils on some upper buds had begun to turn orange and red, and our plant was maturing. A sign that our plant was reaching the end of her flowering period.

Throughout week ten, our N13 Kush continued to impress us with her rapid development.

The aroma became increasingly apparent and began to emit a pungent earthy, piney aroma that grew more intense with each passing day. By the end of the tenth week, our N13 Kush looked fully developed, but it was evident by the clear trichomes that the buds were continuing to mature.

During week eleven, we stopped supplementing nutrients and began our final flush with pH-balanced water. Flushing the root zone eliminated any nutrients that may have been present in the soil. A large majority of the lower growth had filled out, and buds along the main stem had grown to reach the main cola. Lower buds had grown firmer and appeared thick and chunky. 

As week twelve approached, our N13 Kush Feminized’s large, broad fan leaves had started to lose pigmentation and began to turn a deep yellow. The stems of the fan leaves, by contrast, had turned a deep shade of purple. This was a natural indication that our plant had come to the end of her flowering period, and it was time for harvest.

At this stage, the main cola was magnificent. Its swollen calyxes were fully covered in pistils and trichomes. Thick, resinous buds from the lower nodes had grown together to form a massive cluster of dense buds. In addition, small sugar leaves around the apical cola had now begun to fade to a lighter green. 

It was now apparent that most of the white pistils had turned into a vibrant mix of orange and red. Though we don’t gauge a plant’s maturity on pistil colour, it still served as a good indicator. Top buds on the lower branches had developed into decent-sized colas. Smaller yet still sizable buds clustered around each node, filling the remaining internodal gaps. All buds were thick, heavy and covered in a frosty layer of trichomes.  

In addition, our N13 Kush’s aroma had become increasingly alluring. As the plant reached the end of the flowering stage, the earthy, piney aroma became even more prominent, and subtle berry notes developed in the bouquet. 

After a whole week of flushing, and a close examination of our stunning plant, we observed that approximately 60-70% of the trichomes had turned to a deep amber hue, indicating our plant was finally ready to be harvested. Dominated by the apical bud, the entire plant was covered with dense buds coated in trichomes, and at the start of week thirteen, we harvested our N13 Kush.


Our N13 Kush was cut down whole with pruning shears at the stem. Any remaining fan leaves were removed, branches were separated and hung upside in our dark drying room.

The drying room temperature was maintained between 18-20°C, and fans ensured constant airflow. After two weeks in the drying room, our plant’s stems could be snapped without bending, letting us know that our harvest was relatively dry. 

We removed the remaining sugar leaf from our buds and lightly trimmed them by hand.

The buds had a dense structure and were coated in crystals. After trimming, our scissors and gloves were caked in sticky resin.

Our manicured buds were then placed into glass mason jars for curing. These jars were opened multiple times a day, usually for around 30 minutes at a time. This allowed for gas exchange and the introduction of fresh oxygen.

We transferred the jars to a drying room for long term storage. This sealed space features a ventilation system that allows moisture to pass, maintaining an internal RH of 62%. These conditions enabled our buds to retain their spectacular terpene profile.

After a few months in the jars, our buds were finally ready to be enjoyed. As expected, the aroma had developed significantly, and presented an intoxicating bouquet rich with berry and pine. Laboratory results revealed our N13 Kush Feminized to have an outstanding THC level of 19.98%. 

Terpene profile

The most dominant terpene in our N13 Kush is myrcene and can be accounted for in its pungent, earthy aroma. The presence of caryophyllene, pinene and limonene are also likely to account for the piney, berry undertones present in this exquisite indica strain. N13 Kush delivers an immediate hit of earthy, piney notes when consumed. Upon exhaling, sweet berry hints are evident, offering an almost candy-like flavour. 

N13 Kush’s indica lineage is immediately evident upon smoking. A fast-acting rush of relaxation soothes the consumer, leaving them with a mellow, body-heavy high. The 10% sativa genetics can be detected in the lack of overwhelming sedative effects, and users are treated to an uplifting, creative experience that develops into a mellow, relaxing stone.

N13 Kush provides excellent effects for those who are turned off by the couch locking impact of pure indicas yet still seek the medicinal and relaxing benefits of a heavy indica strain. The touch of sativa in the genetics helps prevent this strain from proving overwhelming. Ultimately, this cultivar’s vibrant assortment of terpenes certainly makes for a highly satisfying and flavourful cannabis experience.

The outcome

Though this compact indica-dominant plant remained under one meter, she managed to produce a tremendous yield of 107 grams of dense dried cannabis flower.

N13 Kush is beloved by growers for its potential to produce larger-than-expected harvests, made all the more remarkable by the plant’s relatively small and compact statue. It is an excellent strain for inexperienced growers or those limited by space. Its compact growth pattern and substantial yields make it a natural choice, particularly for indica lovers.

Grown from seed to harvest in a total of thirteen weeks, N13 Kush Feminized certainly rewarded our efforts, offering a substantial and high-quality yield.

  1. Io sto coltivando in esterno in vaso.
    Ho germinato il seme il 19/4/24 e l’ho interrato il 22/4, per veder spuntare la piantina il 25/4.
    Ho annaffiato con acqua demineralizzata (inizialmente 5 ml, aumentando gradualmente).
    L’ho travasata in un vaso da 40cm il 23/5/24.
    Ad oggi la pianta sta benissimo. È alta 47/48 cm.
    Sono praticamente quasi due mesi e non vedo problemi, ma sembra ancora in fase vegetativa.
    Spero bene
