SubCool Seeds Qrazy Train F2

Strain Overview

Qrazy Train F2 Regular Cannabis Seeds by SubCool are a balanced 50% Indica / 50% Sativa hybrid bred from Blood Wreck x Querkle. Qrazy Train F2 seeds combine vigorous growth, strong branching, rich terpene expression, resin production, and heavy yield potential with a fast 55–60 day flowering period.

Genetics and Lineage

Qrazy Train F2 seeds combine the strength and productivity of Blood Wreck with the fruit-forward characteristics of Querkle. Train Wreck-based genetics contribute vigorous growth, while Querkle adds Space Queen-influenced fruit and aromatic complexity. As an F2 generation, these regular seeds offer increased phenotypic variation for selection.

Growth and Structure

Qrazy Train F2 plants typically grow medium to tall with vigorous branching and strong structural support for multiple flowering sites. Plants develop quickly during flowering, with mature resin production often appearing around day 45. The cultivar performs well indoors and outdoors.

Flowers and Resin

Qrazy Train F2 seeds produce spear-shaped, dense flowers with a favorable calyx-to-leaf ratio and heavy trichome coverage. Plants may display burgundy and amber coloration late in flowering, adding visual appeal to the resin-rich flowers.

Flowering and Yield

Qrazy Train F2 seeds typically finish in 55–60 days and can deliver heavy yields under optimal conditions. Rapid flower development, strong branching, and multiple bud sites make this cultivar well suited to growers seeking productive harvests with a shorter flowering cycle.

Flavor and Aroma

Qrazy Train F2 seeds produce a complex terpene profile featuring spicy skunk, rich grape, fuel, melon, fruit, and subtle champagne-like sweetness. The combination creates a bold, layered aroma influenced by both Blood Wreck and Querkle genetics.

Seed Type and Breeding Potential

Qrazy Train F2 seeds are regular cannabis seeds, producing both male and female plants for breeding and phenotype selection. The F2 generation offers opportunities to explore variations in structure, coloration, resin production, and terpene expression while preserving the core traits of the original cross.
