About Hp13
Hp13 is a reliable hybrid that combines the resin and stability of Northern Lights with the lift of Haze. It suits growers who want consistent THC-forward results in temperate regions and performs well both indoors and outdoors with sensible canopy management.
Hp13 is a balanced hybrid with a slight sativa dominance. It delivers a blend of cerebral lift and physical calm.
THC levels for Hp13 typically sit between 18% and 22%. This gives a clear psychoactive presence without extreme intensity.
Hp13 is not bred for high CBD and usually measures low, around 0.5–1.5% CBD. The low CBD emphasises the THC-driven effects rather than pronounced cannabidiol benefits.
Hp13 descends from Northern Lights x Haze and carries traits from both parents. The lineage produces vigour, resin production and a distinct aromatic profile.
Seeds are offered as feminised to simplify cultivation and reduce male plants in the crop. Feminised seeds give reliable female-dominant crops for consistent yields.
Growing Hp13 in a temperate southern England climate requires steady attention to humidity and airflow. It is best suited to growers with some experience who can manage those variables.
Flowering time ranges from eight to ten weeks under optimal conditions. Indoor growers can expect reliable schedules while outdoor timing depends on local seasonal shifts.
Yield is medium to high when trained and fed correctly. Indoor yields of around 450–600 g/m² are achievable and outdoor plants can produce 400–800 g each in a good season.
Plants develop a medium-tall structure with spaced internodes and sturdy stems. Expect 60–120 cm indoors and up to 2.2 m in a generous outdoor setting.
Indoors Hp13 responds well to Sea of Green or Screen of Green setups in Hertfordshire. Outdoors in Hertfordshire it benefits from a sheltered position away from prevailing winds.
In Hertfordshire the temperate southern England climate favours Hp13 but growers should guard against late-season rain. Good drainage and site selection will protect buds from mould during wetter periods.
The high-THC profile gives a clear uplift that sharpens focus for many users. A mellowing body effect follows, making it suitable for daytime to early evening use.
Flavour leans earthy with bright citrus top notes and a pine finish. The smoke is clean and the terpene mix is persistent through vapourisation.
Frequently Asked Questions
Common questions about this strain, covering growth, effects, and suitability for UK conditions.
Use 18/6 for veg and switch to 12/12 for flowering; maintain stable light hours to avoid stress.
Water when the top 2-3 cm of medium is dry and avoid overwatering; increase feeding concentration slightly during peak bloom.
A balanced NPK schedule with a bloom boost in flowering works well; add silica for stem strength and mycorrhizae for root health.
Ensure good airflow, avoid dense canopies and site plants where morning sun dries dew quickly; remove low foliage and keep spacing between plants.
Flush with plain water for 7-10 days before harvest to reduce residual nutrients and improve smoke quality.
Yes, Hp13 responds well to living soil with compost teas and slow-release amendments; microbial life helps nutrient uptake and resilience.
Selective pruning and topping encourage an even canopy and better light penetration; avoid heavy defoliation late in flowering.
Dry slowly for 7-10 days in a dark, ventilated room then cure in jars for at least two weeks, checking humidity regularly.
Yes, controlled climate cannabis growing lets you manage humidity and temperature precisely, reducing mould risk and improving resin production for Hp13.
Look for spider mite webbing, thrip speckling and aphid clusters; treat early with biocontrols or low-toxicity interventions to limit spread.
