About 91 Octane

91 Octane is a sativa-leaning hybrid bred from NYC Diesel x OG Kush. I grow it in my greenhouse in Devon and find it gives solid yields and a strong diesel flavour. Plants stay medium height and suit most UK grow rooms when you train them. Flowering finishes in eight to nine weeks indoors and produces dense, resinous buds that respond well to a careful cure.

Grow Difficulty:

This strain suits growers with some experience due to moderate vigour and a need for regular trimming. In the UK's humid summers you will want good ventilation in a greenhouse to reduce mould risk.

Flowering Time:

Indoor flowering usually finishes in eight to nine weeks. Outdoors in the UK that places harvest around late September into October in milder spots like Devon or Kent.

Yield:

Yields are generous for a hybrid, reaching up to 500 grams per square metre indoors and strong outdoor weights in sheltered sites. Greenhouse growers in Bristol or Manchester often hit the upper end when they train and feed well.

Height:

Plants remain a medium height and suit most home grow rooms, typically between 0.8 and 1.5 metres. If you grow indoors you will find they respond well to topping and SCROG to control stretch.

Environment:

91 Octane performs well both indoors and outdoors. In damp British weather a greenhouse or covered site helps you protect buds from rain and humidity.

Climate:

91 Octane prefers a mild maritime climate and suits sheltered UK sites from Cornwall up to Kent. In Scotland and the Highlands you will most likely need a greenhouse to control humidity and finish buds.

Common question Posted by Urbanseedbank Answered
Q
My buds risk mould in late autumn, what do you suggest?
A
Verified answer
Move plants into a greenhouse or indoor space with dehumidification and increase airflow around colas. Remove lower growth that traps moisture and target a dry finish.
Common question Posted by Urbanseedbank Answered
Q
How do I get the most diesel aroma to come through?
A
Verified answer
Avoid over-flushing too early and cure slowly to preserve terpenes. A final low-temperature dry helps keep the sharp diesel top notes intact.
Common question Posted by Urbanseedbank Answered
Q
Which nutrients give the best resin production?
A
Verified answer
Higher potassium and phosphorus in flowering boosts bud density and resin. Use bloom-specific feeds and add a resin booster in the final weeks.
Common question Posted by Urbanseedbank Answered
Q
Can I run 91 Octane in a small tent with 60 cm height?
A
Verified answer
Yes if you keep plants short with topping and LST early. SCROG with a low canopy works well in compact spaces.
