JAHRassic (JAHmagic x Black Amber) - Compound Genetics

JAHRassic (JAHmagic x Black Amber) Feminized Seeds by Compound Genetics

JAHRassic is far from the typical gas-only American strain. With this cross, Compound Genetics explores a much more layered and modern terpene profile.

On one side is JAHmagic, the Jahnetics creation bred from Blueberry Yum Yum x Purple Haze, known for its sweet cotton candy aroma, ripe fruit notes, and subtle chemical-earth undertones. On the other side sits Black Amber, Fullmoon Genetics’ dark and resinous GMO x OZ Kush Bx2 hybrid, famous for its fuel-heavy funk, earthy depth, and stunning dark coloration.

Together, they create a terpene profile that feels truly exotic: sweet, fruity, creamy, and cereal-like up front, followed by layers of gas, spice, funk, and earth underneath. Extremely loud and incredibly complex.

Exotic visuals with serious USA bag appeal

Visually, JAHRassic delivers everything expected from elite American cannabis genetics.

The plants produce dense, trichome-heavy flowers with phenotypes expressing dark green, purple, and nearly black coloration inherited from the Black Amber side. Swollen calyxes and thick resin coverage give the buds a frosted premium appearance even before curing.

A strain clearly built for standout bag appeal and top-tier extraction potential.

Balanced effects with uplifting energy and body depth

JAHRassic feminized seeds produce plants with a very balanced hybrid effect profile. The JAHmagic influence brings uplifting, euphoric, and creative energy, while Black Amber adds a heavier physical relaxation and long-lasting body effect.

The result is a potent but versatile experience — strong enough for experienced users while still allowing appreciation of the complex terpene profile.

Growing characteristics

JAHRassic shows vigorous hybrid growth with moderate-to-high stretch inherited from the sativa side of JAHmagic. It responds very well to topping, SCROG, and canopy management techniques, producing medium-high yields of highly resinous flowers.

Flowering finishes in approximately 8–9 weeks, with especially impressive indoor results where terpene expression, coloration, and trichome production reach their full potential.

An ideal choice for growers searching for something truly different within the modern USA exotic scene.
