About Supreme Diesel
Supreme Diesel is a sativa-dominant hybrid bred from NYC Diesel x OG Kush that delivers a sharp diesel flavour with citrus overtones and a clear, creative high. It prefers good airflow and careful humidity management, making it suitable for growers who can commit to ventilation and mildew prevention.
Supreme Diesel is a sativa-dominant hybrid with a lively, cerebral character. It pairs diesel pungency with bright, uplifting highs.
THC typically ranges from 18–24% in well-cared-for plants. With careful feeding and light, specimens in Cumbria can reach the higher end of that range.
CBD is minimal, generally below 1%. This strain is not optimised for CBD-focused therapy.
The genetic backbone is NYC Diesel x OG Kush. This cross brings diesel terpenes together with a resinous, stable growth habit from the OG lineage.
Seeds are commonly offered in feminised form for reliable female crops. Some breeders also provide regular and autoflower variants for specific grower needs.
Growing Supreme Diesel in humid greenhouse conditions raises the bar on ventilation and mould prevention. The overall difficulty is intermediate and rewards attention to airflow and leaf hygiene.
Flowering generally takes 8–10 weeks under stable conditions. Outdoor crops in favourable seasons often finish late September to October.
Yields are medium to high when plants receive strong light and regular nutrients. In Cumbria outdoor yields can be slightly reduced without careful moisture management.
Plants form a medium-tall structure with a dominant central cola and vigorous side branches. They respond well to topping and light training to spread the canopy.
Indoors this cultivar performs well under controlled environments, and growers in Cumbria can use SCROG or SOG to optimise canopy. Outdoors in Cumbria it prefers a sheltered sunny site with good airflow to reduce rot risk.
In Cumbria, humid greenhouse conditions can accelerate vegetative growth but increase the risk of bud rot. Managing humidity with ventilation and dehumidifiers is essential when cultivating Supreme Diesel in Cumbria's humid greenhouse conditions.
Effects start with a clear, cerebral uplift that encourages creativity and sociability. The body effect is gentle, producing relaxation without heavy sedation.
The flavour profile is dominated by diesel notes layered with citrus top notes and an earthy base. The finish is herbal with a faint pine undertone.
Frequently Asked Questions
Common questions about this strain, covering growth, effects, and suitability for UK conditions.
It is best for growers with some experience; attention to humidity and airflow is needed to avoid mould.
Moderate to strong nutrients during veg, tapering off in late flower, with attention to potassium and phosphorus in bloom.
In the UK expect a late September to October harvest in mild seasons, checking trichomes for desired amber levels.
Use extraction fans, dehumidifiers, open vents during warm days and remove lower foliage to improve airflow.
It shows a moderate to strong stretch in early flower; plan height and consider pre-flower training.
Yes, it can be grown outdoors but choose a sunny, sheltered spot and be vigilant about rain and humidity to reduce rot.
Aphids, spider mites and fungal gnats can appear; regular checks and biological controls help limit infestations.
Yes, it responds positively to low-stress training and topping, which improve bud sites and light penetration.
Dry slowly at 18–21°C with 45–55% humidity, then cure for 2–6 weeks in jars, burping daily initially.
Potency varies with nutrition, light and climate; well-managed plants will hit the 18–24% THC window consistently.
