About Old Growth Og
Old Growth Og is a robust indica-dominant hybrid bred from OG Kush x Northern Lights to combine heavy resin, unmistakable kush aromatics and compact, hardy structure. It suits intermediate growers who can manage humidity and airflow, and it rewards careful canopy management with dense, aromatic flowers that perform well for both recreational and therapeutic uses.
Old Growth Og is an indica-dominant hybrid combining heavy resin production with compact bud structure. It leans towards a classic kush profile while keeping vigour for cooler sites.
THC levels typically range from 18% to 24% across tested phenotypes. That potency produces a clear cerebral lift which settles into measured physical relaxation.
CBD runs low to moderate, commonly between 0.5% and 2% depending on the phenotype. This balance softens the edge of the high without removing psychoactivity.
Old Growth Og originates from an OG Kush cross with Northern Lights to combine aroma and resilience. The cross gives heavy kush aromatics alongside compact, hardy structure.
Seeds are supplied as feminised to simplify canopy management and reduce time spent sexing plants. Feminised genetics suit growers in Belfast who need to make the most of limited space.
Growing Old Growth Og requires intermediate skills to manage mould risk during a rainy autumn harvest season. Active canopy management and prompt airflow measures are essential in damp conditions.
Flowering usually completes in 8 to 10 weeks under stable conditions. Some phenotypes may finish a little earlier while others take the full period to bulk properly.
Yield is medium to high, typically 350–500 g/m² indoors and up to 400 g per plant outdoors in good sites. Wet weather at harvest can reduce usable yield unless buds are protected and dried quickly.
Plants remain medium in height, often between 80 and 140 cm when trained. They form stout central colas and a bushy canopy suited to sheltered plots near Belfast.
Indoors, Old Growth Og does well in controlled tents with SCROG or SOG methods to maximise bud sites in Belfast. Outdoors, it favours sheltered plots with good airflow and late-season protection from persistent rain in Belfast.
In Belfast, with its cool, maritime climate and rainy autumn harvest season, growers must prioritise mould prevention and drying space. Raised beds, protective covers and timely harvests help preserve quality through wet autumns.
Effects begin with a bright, focused uplift that eases into deep physical calm. At higher doses the variety takes on a sedative quality that helps with sleep.
The flavour profile blends earthy pine and sharp citrus top notes with a resinous herbal backbone. A peppery, slightly spicy finish lingers on the exhale.
Frequently Asked Questions
Common questions about this strain, covering growth, effects, and suitability for UK conditions.
Old Growth Og shows moderate resistance thanks to good bud structure, but dense flowers still need airflow and regular inspection to avoid grey mould in damp weather.
Use a balanced NPK diet in veg, then shift to higher phosphorus and potassium during flowering; reduce nitrogen late in flower to aid resin and terpene development.
Yes, it can finish outdoors in northern climates if planted early and given shelter, but late-season rain increases risk so plan for coverings or early harvests.
Begin prevention from the first weeks of flowering by improving ventilation, lowering humidity and removing lower growth that blocks airflow around bud sites.
SCROG and topping work well to create an even canopy and reduce internal humidity pockets; low-stress training is useful for preserving vigour in cooler conditions.
Dry slowly for 7–14 days in 50–60% relative humidity, then cure sealed jars for at least four weeks to round out flavours and reduce chlorophyll harshness.
Yes, with attention to shelter and airflow Old Growth Og can be grown successfully in Belfast, but expect to manage damp conditions during harvest.
Aphids, spider mites and fungal gnats can be problems; keep plants healthy, inspect regularly and use biological controls where possible.
Old Growth Og ranks well among cool climate cannabis strains because of its compact growth, predictable flowering time and better-than-average resistance to damp weather.
Yes, it responds well to organic feeding and compost teas, but organic matter can increase humidity so maintain airflow and avoid overwatering.
