Critical Mass
Critical Mass is your ideal choice for an abundant, high-quality harvest without complications. Enjoy dense, resinous buds with an intense flavour and relaxing effects. Perfect for novice and expert growers alike, this strain guarantees a satisfying experience, from grow to smoke.
Critical Mass is a cannabis strain that has won over growers all over the world, and with good reason. It was born from a cross between the legendary Afghani and the potent Skunk #1, an explosive combination that brings together the best of both worlds. Developed by the renowned Mr. Nice seed bank, it was perfected by master breeders Shantibaba and Nevil Schoenmakers, who created a sturdy, high-yielding plant.
Critical Mass stands out for its huge, dense buds, so heavy that they often need staking to stop the branches snapping. The colours of its flowers range from dark green to shades of purple, with orange pistils adding a spectacular touch. They are covered in a thick layer of trichomes that makes them look out of this world, a true visual spectacle.
Flavour and effects
The flavour of Critical Mass is a delicious blend of citrus, fruit and herbs, with very clear notes of lemon and lime and a fruity undertone that will wake up your taste buds with every toke. The aroma is just as intense and penetrating, filling the room with a sweet, fruity fragrance that is impossible to ignore.
The effects of Critical Mass are potent and balanced. With THC between 15% and 20%, it delivers a highly psychoactive initial rush, followed by a relaxing, calming comedown. It's ideal if you want to unwind after a long day without losing that sense of euphoria and joy. It also contains around 1% CBD, which rounds off the high and gives it a smoother, more balanced feel.
Critical Mass terpenes
Critical Mass stands out not only for its cannabinoid profile but also for its rich terpene make-up. The most prominent are myrcene, caryophyllene and limonene.
Myrcene brings herbal, earthy notes and is typical of heavy, relaxing night-time strains. Caryophyllene, with its spicy, peppery touch, adds warmth and depth to the flavour. Finally, limonene adds a refreshing citrus aroma, in keeping with its energetic, cheerful side.
These terpenes not only enrich the aroma and flavour of Critical Mass but also shape its effect, delivering a complete and satisfying experience.
Yield and flowering time
Critical Mass is known for its impressive yield both indoors and outdoors. If you grow indoors, you can expect up to 750 grams per square metre, especially if you use techniques such as SCROG (Screen of Green) to maximise production. The plant doesn't call for advanced experience, so even a novice grower can easily reach 600 grams per square metre with a good LED panel.
Outdoors, Critical Mass can become a real giant of up to 2.5 metres tall. With enough space and under optimal conditions, yields can exceed 1000 grams per plant. It's perfect if you want abundant, high-quality harvests without complications.
The flowering time of Critical Mass is relatively short, one of its big advantages. Indoors, plants will be ready to harvest 45 to 55 days after switching the photoperiod to 12/12. Outdoors, flowering begins in late July or early August, and you can harvest in the second half of September. This fast flowering makes Critical Mass an ideal choice if you want quick, efficient results.
How to grow Critical Mass
Growing Critical Mass is a rewarding and straightforward experience. This strain is perfect for novices and experts alike. Its growing difficulty is low, which makes it an ideal option if you're new to growing cannabis. It doesn't need excessive care and can cope with a bit of neglect without the quality of the harvest suffering.
For the best results, it's important to give Critical Mass a suitable climate. It prefers daytime temperatures of 20 °C to 27 °C and night-time temperatures of 15 °C to 21 °C. It thrives in low-humidity environments, especially in flower, to prevent mould given how dense the buds are. In humid climates, pruning is advisable to improve airflow and reduce the risk of disease.
Critical Mass is resistant to common pests, which makes it easier to grow both indoors and outdoors. Even so, it's always wise to keep a close eye on it to spot any sign of infestation and act quickly if needed. Its sturdy, compact structure helps it bear the weight of the buds, but adding stakes towards the end of flowering is recommended.
