M-39 by Quebec Cannabis Seeds
Northern Lights #5 × Skunk #1
M 39, a predominantly indica strain with Canadian origins, is recognized for its calming effects and a distinctive skunky-citrus aroma. Bred by Quebec Cannabis Seeds, it is a well-regarded cultivar known for dense, resinous flowers.
Appearance
M 39 produces dense, resin-coated buds characteristic of indica varieties. The flowers typically form medium-sized colas with tight calyxes and a high calyx-to-leaf ratio, making them efficient to trim. Buds are generally olive to forest green, often accented by orange to amber pistils, and may exhibit faint purple hues in cooler environments. The heavy resin production results in frosted trim, suitable for extraction.
Aroma & Flavor
The aroma of M 39 is often described as classically skunky with a bright citrus accent, particularly lemon zest. Underlying notes can include earthiness, pine, and herbal undertones, with some phenotypes exhibiting a peppery spice. Upon grinding, a skunky musk is followed by sweet citrus and hints of black pepper. The flavor profile closely mirrors the aroma, delivering a skunk-laced lemon taste with a gentle, earthy sweetness and a prominent peppery spice on the exhale.
Effects
Consistent with its indica heritage, M 39 is primarily known for its calming effects. It offers reliable relaxation, often described as a soothing body high. While not explicitly detailed in the source, the indica-dominant nature suggests potential for tranquility and unwinding.
Terpenes & Cannabinoids
M 39 typically exhibits a THC content ranging from 16% to 20%, with CBD levels below 1%. The terpene profile can vary, with NL5-leaning phenotypes often featuring myrcene, while Skunk-leaning expressions may show balances of limonene and caryophyllene. These terpenes contribute to the strain's characteristic earthy, citrus, and peppery notes.
Origins & Lineage
M 39 was developed by Quebec Cannabis Seeds and is widely recognized as a cross between Northern Lights #5 and Skunk #1. This pairing is historically significant, having helped define modern cannabis genetics. The strain's development focused on performance under artificial lighting, contributing to its reputation in Canadian indoor cultivation.
Growing
M 39 is noted for being somewhat finicky and challenging to cultivate properly, despite its commercial lineage. It requires careful climate management, particularly regarding airflow and humidity, due to its dense bud structure which can be prone to mold. The plant exhibits a compact, robust structure suited for indoor setups and sea-of-green methods, with short to medium internodal spacing.
