| Effect — head | Bright cerebral lift — focused, creative, conversational |
| Effect — body | Light, mobile, energizing — body remains engaged |
| Duration | Active onset with a tapering finish — sativa lift is shorter-lived |
| Time of day | Daytime / creative work — activating cerebral arc |
| Cultivation | Greenhouse or outdoor preferred · benefits from longer flower window and vertical room |
| Expected variation | high variation — every seed is a unique cross of two distinct parents; select your keeper |
| Select for | Phenos expressing dominant Joseph traits will be most expressive |
| Amplified pheno | Hunt for Afghani-leaning phenos — that heritage appears on both sides and will express most intensely |
| Amplified heritage | Afghani landrace appears on BOTH parental lines — this strain expresses Afghani heritage with amplified intensity vs single-side crosses |
| Foundational signature | Distinct foundational signature: Joseph, Sour Diesel, Chemdawg |

The record · 3 sections
Anchor your senses with Cornerstone, a foundational hybrid that unites the unrelenting potency of Headwrecker with the robust, diesel-tinged depth of Joseph OG.
Headwrecker's piercing pine and Joseph OG's rich, kushy fuel notes meld into a formidable flavor profile.
Notes of diesel and OG kush dominate, underscored by a lively zing of limonene and the earthy depth of pinene and caryophyllene.
Buds are densely packed, with a generous resin coating that reflects the strain's balanced, hard-hitting hybrid lean.
