Black Cherries by Old School Genetics

Black Cherries takes a bright, candy-shop fruit profile and drags it straight through a kosher deli of earthy kush and fuel. Bred by Oldman Green at Old School Genetics, it pairs Tropicana Cherry (Tropicana Cookies x Cherry Cookies F3 from Relentless Genetics) with the Kosher Kush cut that OSG has kept since its original DNA Genetics selection. The result is a 60% Indica / 40% Sativa hybrid that smells like a split-open sour cherry dusted with orange peel and a whiff of diesel.

This strain belongs to the Kosher Kush Hybrids LTD series, a limited run of six feminized crosses in which every release uses Oldman Green’s reversed Kosher Kush as one parent. Within that family, Black Cherries is the fruit-forward expression: the Tropicana Cherry side brings citrus and cherry, while the Kosher Kush side supplies structure, density and that unmistakable earthy-gas backbone.

Indoors the plants stay at a manageable medium height with a slender frame and only moderate stretch, which makes them a natural fit for Sea of Green setups and crowded tents. Expect flowering to finish in 8.5-10 weeks (60-70 days), with Old School Genetics estimating yields of up to around 700 g/m² (2.29 oz/ft²) in a dialed room.

As the weeks pass, many phenotypes start blushing purple across the calyxes and sugar leaves. It is common but not guaranteed, and when it shows up the contrast with the frosty white trichomes is striking.

Flavor, Effects, and a Resin Coat Built for Rosin

Break a cured bud and the first thing that jumps out is tart sour cherry and fresh orange, followed by sharp lemon rind and a tropical fruit sweetness inherited from the Tropicana side. Underneath, the Kosher Kush keeps everything grounded with earthy kush and a gassy, diesel edge that lingers on the exhale. Think cherry soda poured over crushed ice in a gas station parking lot: sweet, sour and a little bit dirty.

The expected terpene mix centers on limonene, caryophyllene, myrcene and linalool, which matches the citrus-forward nose and the peppery, earthy undertone.

The flowers grow elongated and heavy, wrapped in a thick blanket of dense, milky trichomes. Old School Genetics points to very high resin output, and the heads come off cleanly, so growers who press rosin or run ice water hash have a lot to work with here.

The high is reported as balanced and functional. It opens with an uplifted, creative mood and good mental clarity, then settles into a relaxed body feel that eases tension without pinning you to the couch.

Growing Black Cherries Feminized Seeds

Each pack contains 6 feminized seeds, so every plant you germinate should be a flowering female. The plants grow with good vigor and respond well to a short veg followed by a dense SOG canopy, while topping and light LST help even out the colas if you prefer to grow fewer, bigger plants.

Mold resistance is described as moderate, so keep humidity in check and the airflow strong during late flower, when those long, resin-heavy buds are at their densest. Outdoors, this strain does well in warm, dry, Mediterranean-type climates, where it typically finishes in early October.
