Summary / Suitability
C5 Haze Bx is a preservation and reconstruction of one of the earliest Dutch haze hybrids. It expresses the long-flowering, high-vigor characteristics typical of 1980s sativa breeding. The plants develop narrow leaves, long internodes, and extensive vertical stretch during flowering. Best suited for warm climates, greenhouses, or controlled indoor environments with strong light intensity and stable photoperiods. This cultivar is primarily for breeders and haze specialists who want to work with a near-pure haze expression rather than a production hybrid.

Genetic Background
The C5 Haze Bx lineage descends from Nevil’s Northern Lights #5 × Haze C, a foundational hybrid from the late 1980s. Lost Phenos C5 Bx combines Reefermans Amsterdam C5 clone with male selections from Santero’s Meridian Haze (C5 Bx2), derived from a line made using early Sensi Seeds Jack Herer males with the original C5. This genetic reconstruction keeps the C5 profile nearly intact, maintaining the long flowering time, narrow leaf morphology, and citrus-incense terpene profile characteristic of the original Dutch haze cultivars.

Plant Characteristics
Plants are vigorous and tall with narrow leaflets and open branching. Stretch is substantial, with plants tripling in height during the first month of flowering. Buds form in long, loosely stacked colas with visible calyx separation. Resin develops early but continues to build until full maturity, producing a thin but sticky coating across the entire inflorescence.
Optimal growth requires consistent light, low nitrogen feeding, and balanced soil pH. Living soil enhances aromatic output and resin quality. Flowering takes 12-18 weeks depending on phenotype, with most plants completing between 14-16 weeks.

Flower & Aroma Profile
The aroma profile combines lemon-lime, metallic haze, and cedar tones. In late flower and curing, this shifts to frankincense and dry wood. The cured flower has a sharp, effervescent haze scent and a lingering resin finish. Smoke is light but expansive, carrying the familiar sweet-citrus haze flavor associated with Nevil’s early work.

Growing Tips (Indoor & Outdoor)
Indoor: Needs vertical clearance and intense lighting. Suitable for SCROG or light training to manage stretch. Maintain moderate feeding and stable environmental parameters—light leaks or stress can cause delay in flowering.
Outdoor / Greenhouse: Performs best in full-sun environments with deep soil and steady airflow. Requires long, uninterrupted flowering periods to reach full maturity. In living soil systems, it develops more aromatic complexity and resin depth.

Effects & Potency
C5 Haze Bx produces an active, cerebral effect with long duration. The onset is fast and clear, building into a focused, euphoric high. It lacks strong physical sedation and is typically functional when used in moderation. Potency is medium-high, with clean, uplifting energy and gradual comedown.

Cultural Context
The C5 Haze lineage represents a major transition point in global cannabis breeding—from early landrace-based hybrids to refined Dutch haze cultivars. Its influence can be seen across multiple classic lines including Jack Herer, Super Silver Haze, and Amnesia. This backcross retains the long-flowering, narrow-leafed sativa structure and high-energy profile of the original 1980s haze cultivars, serving as a genetic reference point for breeders and collectors interested in preserving early European haze genetics.
