Purple Onyx
Parents
The Purple Onyx strain is a hybrid bred from a cross of Ice Cream Cake and Jealousy, grown primarily by Michigrown out of Michigan's cannabis scene in the 2020s. It's a cultivar that draws on Gelato-family genetics through its Jealousy parent, resulting in a rich, layered profile. The aroma opens with ripe berries and citrus peel, grounded by earthy spice and a subtle nuttiness. On the inhale, you'll pick up creamy vanilla and bright floral notes that carry through the exhale.
Myrcene, limonene, and caryophyllene drive the experience here, and reviewers often describe a calming, full-body relaxation that settles in without feeling heavy — though fans of the strain do say it brings a warm euphoria that pairs well with a quiet evening at home. The buds themselves are dense and coated in frosty trichomes, with deep purple hues that intensify toward the end of the grow cycle. It's a striking flower that looks as good as enthusiasts say it smokes.
Purple Onyx is a moderate-difficulty strain that stays compact at 3–4 feet indoors, making it a good fit for growers working with limited space. Outdoors, it can stretch to 5–6 feet with a bushy growth habit and thrives in warm, Mediterranean-style climates with temperatures around 68–80°F. The dense, trichome-heavy bud structure means you'll want to keep humidity at 40–50% during flowering to avoid mold. Expect a flowering window of roughly 8–9 weeks, and yield estimates based on parent strain data typically fall around 350–450 g/m² indoors or 14–18 oz/plant outdoors when conditions stay dialed in.
