| Generation | F1 First-filial hybrid |
|---|---|
| Stability | hybrid vigor |
| Lean style | sativa-dominant |
| Lean | 30% indica · 70% sativa |
| Structure | Tall, open architecture with longer internode spacing — sativa habit from the foundational lineage |
| Leaf | Narrow-leaf morphology likely; slender fan leaves with pointed fingertips |
| Flower density | Airier flower formation — elongated colas with calyx-stacked structure |
| Trichome | Heavy trichome production — foundational lineage carries frost-monster heritage |
| Cannabinoid | Heavy THC character — fuel/kush/OG lineage carries traditional potency markers |
| Terpenes | caryophyllenemyrcenelimonene |
| Traits | sourdieselfuelskunktanniczestymuskpotent |
| 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 |

The record · 3 sections
Haarlem emerges as a balanced hybrid that channels the electric energy of its legendary parents into a singular, potent experience.
This cross unites the sharp, zesty diesel punch of East Coast Sour Diesel with the heavy, sedative resin production of Anesthesia to create a truly unique profile.
The resulting flavor profile hits the palate with aggressive notes of sour fuel and pungent skunk, driven by a rich blend of caryophyllene, myrcene, and limonene.
Dense buds form tight, rock-like structures that are heavily glazed in thick resin, promising substantial yields for the cultivator.
