Few aromas are as recognizable as UK Cheese, and OSG Cheese brings that legendary funk back with some extra muscle. As part of the Oldies Never Die series by Old School Genetics, Oldman Green crossed the UK Cheese (Exodus Cheese 87 clone) with his Old Widow (90’s).
The goal was simple: keep the pungent, rancid cheese and skunk character that made Exodus Cheese famous, while improving the plant. OSG Cheese shows more vigor and branching than the original clone, grows fast and builds a rigid, compact structure. This is a 60% Indica / 40% Sativa hybrid, and each pack holds 6 feminized seeds.
Production is solid. Growers report around 500 g/m² (1.64 oz/ft²) indoors and up to 700 g/plant (24.7 oz/plant) outdoors. Flowering takes approximately 9 weeks (about 65 days), and outdoor plants in the Northern Hemisphere finish around mid-October.
One word of warning: the smell is intense and persistent. A carbon filter is strongly recommended long before harvest.
Aroma, Flavor, and Real Old School Funk
Open the jar and there is no mistaking it. OSG Cheese delivers that sharp, funky, slightly rancid cheese note backed by deep, dank skunk: the “real skunk funk from the Old School” the breeder set out to preserve. The Old Widow side adds a resinous backbone without washing out the Cheese character.
The terpene content is high, and it shows in the smoke: savory, pungent and lingering. Fans of classic UK Cheese will feel right at home, and newcomers will understand why the cut built such a following.
Old School Genetics hasn’t published a detailed effect profile. With a 60% Indica lean and Cheese and Widow in the pedigree, expect an indica-leaning hybrid experience rather than a racy sativa buzz. With THC reported around 22%, it deserves some respect.
For hash makers, OSG Cheese is a strong candidate: plenty of terpenes, good resin coverage and a calyx-heavy structure that makes the trim and the wash easier.
