Black Opz is where EZ Seed Bank's two foundation lines collide — NYZ Black Scotti crossed with Zookz, stacking biscotti, sour D, Zkittlez, OG, and gelato flavor into a single heavy-yielding, therapeutic cross. Some phenos blend all five, some lean Zkittlez-dominant, some go gassy. A stoney indica effect without the paranoia.

About Black Opz
Black Opz sits at a unique intersection in the EZ Seed Bank catalog — it's the point where the biscotti/gas character of NYZ Black Scotti meets the Zkittlez candy frost of the Zookz line. The mother brings the gassy, biscotti-forward backbone (Black Scotti's documented Biscotti x Zhit lineage layered with NYZ's sour D and Zkittlez influence), while the Zookz father stamps its signature frost coating, Zkittlez candy, and OG/gelato character across the progeny. The result is a flavour spread that covers biscotti, sour D, Zkittlez, OG, and gelato — with individual phenotypes expressing that range differently. Some blend all five into one complex profile, some lean hard toward Zkittlez dominance, and others push gassier.The flowering window is one of the fastest across either line — some phenotypes can come down as early as day 50, with the full range running to 63 days. Heavy yield with 1.5–2x stretch, and some phenotypes finishing purple under the right environmental conditions. The high is described as therapeutic and stoney without triggering paranoia — a calming indica effect that the breeder specifically positions as suited to those who want heavy stone without the anxiety edge that some potent indicas carry.Seeds are sold for genetic preservation purposes only.

What is Black Opz's genetic lineage?NYZ Black Scotti crossed with Zookz (TK41 x Zkittlez Bx1). This cross brings together genetics from both the Oishii NYZ and Zookz foundation lines.
What terpene profile does this cross carry?A range spanning biscotti, sour D, Zkittlez, OG, and gelato — some phenotypes blend all five, others lean toward Zkittlez dominance or gassier expressions.
How does Black Opz compare to Kuro?Both use NYZ Black Scotti as the mother, but the fathers are different — Kuro uses Oishii NYZ (pushing it toward headband biscotti gas), while Black Opz uses Zookz (adding Zkittlez candy, OG, and gelato frost). Black Opz has a wider flavour range and heavier yield; Kuro is more compact and gas-focused.
Can some phenotypes finish early?Yes — while the full range is 50–63 days, some phenotypes can come down as early as day 50.
Does Black Opz finish purple?Some phenotypes will finish purple, especially with environmental control.
Are the genetics HLVD-tested?Yes — verified clean of Hop Latent Viroid on both parent sides by Tumi Genomics.
