Appearance

Black Opal lives up to its name with dark sugar leaves that can appear nearly black, especially under cooler temperatures and appropriate lighting. The calyxes display deep violet to inky plum hues, contrasted by copper or tangerine pistils. A dense coating of trichomes gives the buds a glittering, gemstone-like sheen.

The bud structure is typically dense to medium-dense, reflecting its indica influence. When trimmed properly, the flowers have a sculpted appearance with a favorable calyx-to-leaf ratio.

Aroma & Flavor

The aroma of Black Opal is often described as nuanced and layered. Consumers may detect sweet and gassy notes, with undertones of spice or floral scents. The flavor profile can echo the aroma, offering a combination of sweet berry and candy notes with hints of citrus and a subtle peppery finish.

Effects

As a hybrid, Black Opal is bred to deliver balanced effects. It can provide a sense of calm and relaxation while also fostering a clear headspace conducive to creativity. The intensity of these effects can vary based on the dosage and the individual's setting.

Terpenes & Cannabinoids

While specific lab results can vary by phenotype and cultivation, Black Opal is noted for its pronounced trichome coverage. The terpene profile often includes Limonene and Caryophyllene, contributing to its complex aroma and flavor. THC levels typically range from 15-25%, with CBD content below 1%.

Growing

Black Opal is considered attractive to both home growers and commercial operations. It generally responds well to modern cultivation techniques such as LED lighting, environmental control, and canopy training. The cultivar is noted for its resin density and resilient trichome heads, making it suitable for solventless extraction.

Origins & Lineage

Developed by GLK Genetics, Black Opal is an indica/sativa hybrid.
