Appearance of the plants

Black Oishii plants grow tall, strong, and full of character. The structure is open and elegant, with long branches that stretch nicely under the right light. As flowering progresses, the buds stack beautifully, forming dense clusters coated in a thick layer of sticky resin. The colors shift into deep shades of purple mixed with dark green leaves, and the trichomes make everything sparkle. When you look at this plant under bright light, it almost glows. It’s the kind of plant that makes growers pause and smile halfway through trimming.

The taste & smell

This strain has one of the most unique flavor profiles from Archive’s lineup. You get a heavy whiff of fuel right away, that unmistakable petrol station scent that true OG fans love. Behind that, there’s a mix of fruity candy sweetness, earthy sherbet, and a touch of floral spice that gives it depth. When smoked or vaped, the flavor starts gassy, then turns slightly sweet with a smooth finish that hangs in the air. It’s strong, tasty, and full-bodied without being overbearing, making it a go-to for people who enjoy complex flavors in their cannabis.

Effects

Black Oishii hits hard and clean. The high begins behind the eyes with a quick wave of euphoria that feels cheerful and clear. Soon after, the body buzz takes over, smoothing out tension and leaving you relaxed but not lazy. It’s the kind of high that lets you think straight while still giving you that comfortable, grounded feeling. The potency here is serious, thanks to the Moonbow influence, so even experienced users will appreciate the power this strain packs. It’s enjoyable day or night, depending on how much you consume.

Growing characteristics/yield

These cannabis seeds perform beautifully in both indoor and outdoor setups. Black Oishii tends to stretch during early flower, so training techniques like LST or SCROG work wonders to shape its tall structure. The flowering time runs between 63 and 70 days, rewarding growers with heavy, resin-rich yields. Indoors, you can expect compact colas that fill trellis nets with ease, while outdoors the plants grow tall and strong under full sun. This strain responds well to good light intensity and careful feeding, giving generous yields of thick, dark buds covered in oily trichomes that scream quality.
