About Critical Mass
Critical Mass is a photoperiod indica-dominant hybrid with a lineage of Skunk #1 and Afghani. It offers a skunky aroma with hints of honey, delivering a relaxing and creative effect that often brings feelings of focus, hunger, and sleepiness. The strain is known for its heavy yields and ease of cultivation, making it a popular choice among growers.
Critical Mass thrives both indoors and outdoors, with a flowering time of 6-8 weeks. It produces dense, compact buds and can yield up to 600 g/m² under optimal conditions. The plant has a sturdy structure and is relatively easy to grow, even for beginners. Its indica dominance ensures a strong physical relaxation, while its THC levels range from 18% to 21%, depending on the version.
- Choose the Crop King Seeds version for the highest THC (21%) and a more pronounced honey and skunk flavor, along with a slightly shorter flowering time. Zamnesia offers a slightly lower THC (18%) but a higher yield potential and a more straightforward skunk flavor profile.
Critical Mass suits growers looking for a dependable, high-yielding plant that delivers a potent indica experience. It’s ideal for those who want a relaxing, creative, and focused high without the complexity of a difficult grow.
