Purple Kush by Kannabia
3 other breeders' versions of Purple Kush — compare flowering times side by side →
The original Purple Kush was a legendary Oakland clone-only cut from the 90s, built on raw Hindu Kush and Purple Afghani landrace genetics. But Kannabia decided to take that iconic, heavy-hitting foundation and twist it up by crossing it with the notorious Black Domina. This wasn't just a simple pollen chuck. They wanted to beef up the yield, speed up the flowering time, and make the plant practically bulletproof for indoor growers, while keeping that devastating indica punch intact.
In the garden, this plant is an absolute tank. It grows exactly how you'd expect a heavy Afghan descendant to grow—short, squat, and bushy with thick stems that can handle some serious abuse. You don't have to worry too much about stretching here. Instead, you'll spend your time thinning out the canopy to get airflow through those dense, rock-hard colas. Drop your nighttime temperatures in the final weeks, and the anthocyanins explode, turning the entire plant into a beautiful display of deep purples and dark magentas.
This isn't the kind of weed you smoke before going out. The Kannabia version of Purple Kush is a straight-up day-ender. It carries a classic old-school aroma—earthy, sweet, and slightly musky with a hint of dark fruit. Once you take a hit, you can feel the Black Domina influence immediately. It wraps around your body like a heavy lead blanket, melting away muscle tension and essentially forcing you to go to sleep. It’s a staple for growers who need reliable, high-grade nighttime medicine that won't give them a headache in the grow room.

Growing Purple Kush: what to expect
As an indica-leaning plant, expect a modest stretch after the flip (roughly 50–100%) and dense bud structure — which makes late-flower humidity discipline the main risk: keep RH in the 40s once buds fatten to stay ahead of mold. Growers familiar with Purple Kush or Black Domina will recognize much of its behavior. Whatever the listing says, the cut in YOUR tent is the ground truth: log feedings, readings, and photos, and let the trends — not the label — drive decisions.
