About P91

P91 is a hardy indica-dominant hybrid developed to perform reliably in cooler climates and damp late seasons. It produces dense, resinous flowers on a compact plant that responds well to training and pruning. Growers in northern temperate regions will appreciate its predictable flowering and balanced effects. With attentive mould prevention and proper drying, P91 yields a flavourful, pine-citrus smoke suited to both recreational and medicinal use.

Grow Difficulty:

P91 is an intermediate grow that benefits from proactive mould management during a rainy autumn harvest season. Good ventilation, timely defoliation and vigilant inspection are important to avoid rot.

Flowering Time:

Flowering usually completes in eight to nine weeks under steady conditions. Outdoors the finish can shift by a week or two depending on late-season temperatures.

Yield:

Yield is medium to generous when plants are trained and fed correctly. Indoor growers can expect around 350–450 g/m² while outdoor plants can reach similar per-plant weights in favourable seasons.

Height:

Plants remain relatively compact with a dominant central cola and multiple productive side branches. Final height often sits between 60 and 120 cm depending on training.

Environment:

Indoors P91 performs well under SCROG and low-stress training and fits comfortably in modest Perthshire spaces. Outdoors in Perthshire it builds dense buds but needs close attention to airflow and trimming as the season turns wet.

Climate:

Growing P91 in Perthshire requires planning for the rainy autumn harvest season and the region's cool temperatures. Careful canopy management and timely harvesting windows are essential in Perthshire to avoid mould and rot.

My P91 outdoor plants have bulging buds but the weather turned wet, what now?
A

Start by removing lower fan leaves to improve airflow, tie up branches for spacing and prepare to harvest early if a long wet spell arrives.

Common question Posted by Urbanseedbank Answered
Q
Will P91 handle a cool night drop to 8°C?
A
Verified answer
Short-term drops are tolerable, but prolonged cold can slow ripening; airflow and sound nutrient levels help plants cope.
