Anti-Armor is the deepest expression of EZ Seed Bank's in-house breeding work — a true backcross reversal that took three generations to build. TK41 was crossed into Zookz, and now Zookz has been reversed back onto TK41 to lock in vigorous growth traits while layering in more Zkittlez candy and frost. Old school kush, Gelato 41, OG, with Zkittlez on the back end.

The Backcross
Anti-Armor is where EZ Seed Bank's breeding methodology is most visible — this isn't a single cross, it's a three-generation backcross reversal designed to achieve something specific. The project started with TK41, the breeder's own creation from reversing Gelato 41 onto Triangle Kush and hunting for an absolute monster of a vigorous plant that threw potent, kushy-dominant buds on a sturdy Gelato 41 body. That TK41 selection was then crossed with a Zkittlez Bx1 male to create Zookz. Now, Zookz has been reversed and pollinated back onto the original TK41 — completing the backcross loop. The intent is precise: lock in TK41's vigorous growth traits while imparting more Zkittlez candy character and frost from the Zookz side.The flavor profile reflects every step of that journey — old school kush and OG from Triangle Kush's Florida OG heritage, Gelato 41 character from TK41's foundation, and Zkittlez candy and frost on the back end courtesy of the Zookz pass. Heavy yielding with approximately 2x stretch, finishing in 63–70 days. The effects are described as strong with a heavy stone — genuinely potent.Seeds are sold for genetic preservation purposes only.

What is Anti-Armor's genetic lineage?TK41 backcrossed through Zookz (TK41 R-Bx1). Three generations: Gelato 41 reversed onto Triangle Kush created TK41, TK41 crossed with Zkittlez Bx1 created Zookz, Zookz reversed back onto TK41 created Anti-Armor.
What does TK41 R-Bx1 mean?R = reversal, Bx1 = first backcross. TK41 has been backcrossed once via reversal through Zookz, which itself carries TK41 genetics — creating a concentrated expression of the TK41 line with added Zkittlez candy and frost.
What terpene profile does this cross carry?Old school kush, Gelato 41, OG kush, with Zkittlez candy on the back end — reflecting every generation of the backcross.
Why was the backcross done?To lock in TK41's vigorous growth traits while adding more Zkittlez candy character and frost from the Zookz side — concentrating the best traits from both directions.
How does Anti-Armor differ from other Zookz line strains?It's the only true backcross in the lineup — TK41 appears on both sides of the cross (as both parent and grandparent through Zookz), making it the most TK41-concentrated expression in the catalog. Flavor leans kush/OG/gelato rather than the broader ranges found in Black Opz or T.M.T.Y.B.
Are the genetics HLVD-tested?Yes — verified clean of Hop Latent Viroid on both parent sides by Tumi Genomics.
