Cannabis seeds Frosted Zinn Auto x 3 Bears Auto from Barney's Farm

Frosted Zinn x 3 Bears OG Auto by Barney’s Farm — a potent autoflower with 24% THC, dense, resinous buds and a rich, spicy-fruity aroma

Frosted Zinn x 3 Bears OG Auto by Barney’s Farm is a modern autoflowering hybrid with a pronounced Indica dominance (70% Indica / 30% Sativa), developed from the resinous genetics of Frosted Zinn and the famous 3 Bears OG from Mephisto Genetics. The THC content reaches 24%, and the full cycle takes just around 70–75 days from seed to harvest. The strain combines compact size, good yield, high resin production and a balanced effect, making it ideal for those who appreciate fast-growing and potent autoflowers from modern breeding programmes.

The main feature of Frosted Zinn x 3 Bears OG Auto is its rich and multi-layered aromatic profile. It is dominated by deep earthy and peppery notes characteristic of OG genetics, complemented by sweet fruity and subtle tropical undertones. The flavour develops gradually: a spicy and earthy base gives way to a mild fruity sweetness, whilst subtle tropical accents emerge on the exhale. This combination makes the strain’s profile rich, distinctive and pleasant all at once.

The effect of Frosted Zinn x 3 Bears OG Auto begins with a noticeable mental lift. The initial sensations are accompanied by euphoria, an improved mood and a gentle creative boost. As the effects develop, the sativa component gradually gives way to a deeper physical relaxation characteristic of indica-dominant genetics. The result is a comfortable blend of positive mood and pleasant physical calm, which is particularly well suited to evening relaxation and relieving accumulated tension.

The buds are dense and heavily covered in trichomes, giving them a distinctive ‘frosted’ appearance by the end of the cycle. Under certain conditions, attractive purple hues may appear on the leaves and in certain parts of the plant, enhancing the variety’s ornamental appeal.

Indoors, Frosted Zinn x 3 Bears OG Auto typically reaches 90–120 cm and completes its full life cycle in approximately 70–75 days, from seed germination to harvest. Under optimal conditions, yields can reach 450–500 g/m². Its compact size makes this autoflowering strain a convenient option for limited space, whilst its dense structure allows for a large number of high-quality buds to be produced on a relatively small plant.

Outdoors, plants can reach a height of approximately 130–140 cm and, under favourable conditions, yield up to 280–350 g per plant. Its autoflowering life cycle means it is not dependent on changes in day length, which is one of the strain’s main advantages.

The high concentration of trichomes is another strong point of this hybrid. The dense buds are covered in a generous layer of resin, giving them a distinctive sparkling appearance. Combined with 24% THC, a complex terpene profile and a pronounced effect, this makes Frosted Zinn x 3 Bears OG Auto an interesting representative of the new generation of autoflowering genetics.
