Q
How did your Chem 91 handle last autumn?
A
I pulled mine a week early and used a pop-up polytunnel; losses to mould were minimal and the terpene profile stayed bright.

About Chem 91
Chem 91 is a sativa-leaning hybrid that blends Chemdawg’s pungent diesel aroma with OG Kush’s resinous structure. It reliably reaches 22–26 per cent THC and offers an uplifting, focused high that eases into a gentle body calm. Growers should expect an eight to ten week flowering window and medium to high yields when plants receive managed feeding and canopy care. In cooler, wetter UK conditions the primary concern is humidity and mould, so sheltering late-season plants or harvesting slightly early often preserves quality. Medicinal users cite benefits for chronic pain, fatigue and low mood, while breeders appreciate the stable resin production and resinous terpene profile.
Grow Difficulty:
Under a rainy autumn harvest season the strain shows moderate resilience but requires vigilant mould prevention. Growers in Leeds should watch humidity closely and maintain strong airflow.
Flowering Time:
Flowering completes in roughly eight to ten weeks depending on phenotype. Some plants finish at the shorter end while others take the full ten weeks to mature fully.
Yield:
Yields are medium to high when plants receive good nutrients and canopy management. Outdoor crops that avoid prolonged wet conditions produce the largest colas.
Height:
Plants reach a medium to tall stature with an open, airy structure. Long side branches respond well to low-stress training and topping.
Environment:
Indoors Chem 91 performs well under SOG or SCROG systems and produces dense, resinous buds. Outdoors around Leeds the strain benefits from a sheltered site and frequent checks for damp spots.
Climate:
Growing Chem 91 in Leeds during a rainy autumn harvest season increases the risk of bud rot and demands proactive canopy control. Bringing plants under cover or harvesting a little earlier helps preserve trichomes and terpene profiles in wet conditions.
