About Chupacabra Auto

The genetic expression of Chupacabra — a 58/42 hybrid — varies meaningfully across phenotypes. Most seeds from this line produce the dominant phenotype: a moderate frame that branches well and produces evenly developed colas with a mix of density and airflow. But expect variation — roughly 1 in 4 plants will lean more strongly in one parental direction, which is part of what makes pheno-hunting this strain interesting. THC testing at 16% across phenotypes, with Caryophyllene consistently dominant.

Genetic Expression in the Grow Room

The dominant phenotype — which appears in roughly 70-75% of seeds — produces a balanced frame that takes to training intuitively. The branching pattern suggests hybrid vigor — aggressive enough to fill space without becoming unmanageable. Flower structure falls between dense and airy, which provides a good balance of bag appeal and mold resistance.

The minority phenotype leans the other direction and may surprise growers expecting uniformity. Flowering completes in 8-10 weeks across phenotypes. Yield: 350-450g/m² indoor, 500-700g/plant outdoor. Height: Tall (4-5 ft). Rated intermediate — the phenotype variation adds a layer of interest without adding significant difficulty. Growing from regular seeds with autoflowering genetics.

What Users Report

Chupacabra at 16% THC produces euphoric, creative sensations that users consistently describe as versatile enough to serve different purposes depending on dose and setting. Lower doses lean more cerebral and functional. Higher doses bring the body effect forward. The Caryophyllene/Myrcene terpene pairing gives this strain a distinctive effect signature that experienced users recognize as different from other hybrids at similar THC levels.

Best suited for flexible use across the day — lighter doses for daytime function, heavier doses for evening relaxation.

Terpene Profile

Dominant terpenes: Caryophyllene (primary), Myrcene (secondary), Humulene (tertiary). This combination produces a nose that develops complexity through the cure — expect the primary caryophyllene character to emerge first, with myrcene and humulene notes adding layers over 3-4 weeks in jars.

Who Should Grow Chupacabra

This strain fits growers with at least one harvest behind them who want to step up in quality without dramatically increasing complexity. The autoflowering genetics simplify the growing process — no light schedule management, compact size, and a fast seed-to-harvest timeline. Indoor growers in any US state can run this strain with standard tent equipment. Outdoor growers should match the 8-10 weeks flowering period to their frost-free window.

Stabilization Notes — What This Means for Your Grow

Chupacabra is an autoflowering line that has been worked through five generations of Royal King Genetics autoflower stabilization. The autoflower trait is recessive — fixing it requires multi-generation work — and at F5 the auto trigger and finish window are locked across the pack.

Breeding Goal

Stabilize the recessive ruderalis trait in Chupacabra for uniform auto-trigger.

Selection Focus

Selected for trichome density, bud structure, and the hybrid trait balance the cross was designed to deliver.
