Brief history and origin of Critical Seeds
To correctly explain the history of Critical seeds, we must go back to the creation of Big Bud, a genotype resulting from the cross between a Skunk #1 and an Afghani. After the success of this variety, the seed bank Mr. Nice Seeds carried out an exhaustive selection from which Critical Mass emerged, the first genetics of this family so famous in the cannabis world and which already has thousands of hybrids in its family tree.
Flavors
The taste of the original Critical Mass is sweet, with earthy undertones and spicy touches, being very pleasant to the palate. In addition, fruity and citrus undertones, reminiscent of lemon, can be appreciated too. Regarding hybrids, tastes will vary according to the phenotype selected for crossing.
Aromas
It is a plant with a strong and intense smell typical of Skunk, where it comes from. It is sweet and fruity, with some hints of wood caused by its predominant terpenes: pinene and myrcene. Critical Mass' aroma is considered one of the most pleasant and recognisable in the cannabis world.
Effects
Its near-perfect balance of sativa and indica produces an intense high that gives way to prolonged tranquillity. With around 20% THC, this strain is ideal for relaxing, but also for opening up the mind. Furthermore, it also reduces anxiety and stress, making Critical the ultimate bedtime ally.
Production
Critical Mass is one of the best-yielding plants on the cannabis scene. In fact, it is notorious for splitting its branches, as they do not have enough strength to support the huge and heavy buds they produce. Therefore, using stakes is recommended to help the plant stand upright and focus its energy to flower production. Indoors it can reach 550 grams per square metre, whereas outdoors, it is close to a kilogram per plant.
Flowering and harvest times
When it comes to flowering times, Critical Mass is one of the fastest strains known. Outdoors, harvest time is expected in early September, while indoors, the buds will be ready for harvesting after about 7-8 weeks on 12/12.

Being one of the strains with the best taste, highest yield and fastest flowering time, it is not surprising that thousands of genetics have been made from Critical Mass. At GB The Green Brand we have the best Critical seeds and their hybrids so that you can enjoy the relaxing effects of the original or the different sensations caused by its variants.
