Thai Neville's Haze
A mythical clone-only sativa blending pure Thai landrace vigor with the architectural perfection of Neville's Haze
What is Thai Neville's Haze?
Thai Neville's Haze is an legendary clone-only strain that represents the pinnacle of old-school sativa breeding. Combining the electrifying, racy energy of a pure Thai landrace with the refined structure and potency of Neville’s Haze (itself a complex cross of Haze, Northern Lights #5, and Shiva Skunk), this cultivar is a time capsule of cannabis history.
Unlike modern polyhybrids bred for speed, this strain is for the patient connoisseur. It produces long, spear-like colas that exude a sharp, metallic incense aroma mixed with tropical fruit and spicy sandalwood. As a clone-only variety, authentic cuts are highly guarded, requiring rigorous HLVD testing to ensure the preservation of its vigorous sativa spirit. Starting with a verified rooted clone is essential, as its flowering time can extend well into the third month of bloom.
Terpene Profile
The aromatic profile of Thai Neville's Haze is classic Haze: sharp, piercing, and complex. It leads with a heavy dose of pinene and terpinolene, creating a "clean" but pungent scent of church incense, old wood, and citrus zest with a spicy Thai pepper finish.
Growing Thai Neville's Haze
Growing this strain is a test of skill and patience. It is known for extreme stretch (often 3x or 4x), requiring height management and early flowering. While the yield is rewarding in terms of quality, the long 12-14 week flowering period means it is rarely seen in commercial rooms but remains a crown jewel for craft growers.
Cultivation Mastery
-
TrainingHeavy LST and ScROG are mandatory to manage its massive vertical stretch
-
FeedingPrefers a lighter nutrient touch; avoid excess nitrogen in late flower
-
PatienceDo not harvest early—the complex terpenes peak in the final two weeks
-
ClimateExcellent mold resistance due to airy bud structure and landrace lineage
Because this is not a "washer" strain (trichome stalks are often long and fragile), focus on preserving the flower. Cure it slowly for 8-12 weeks to let the incense notes fully develop.
Flower Characteristics
Thai Neville's Haze produces wispy, foxtailing colas that are heavily coated in resin but lack the "rock hard" density of modern indicas. This is a deliberate trait of its landrace heritage, allowing for better airflow. The flowers are bright lime green with long, thin amber hairs.
Effects & Experience
This is a pure daytime powerhouse. The effects are almost entirely cerebral, providing an electric, vibrating energy that can be borderline psychedelic for the uninitiated. It is famous for "no ceiling"—meaning the more you consume, the higher you get, without ever feeling bogged down or tired.

Frequently Asked Questions
The name specifies the lineage: a selection of Neville's Haze (created by the legendary Neville Schoenmakers) that has been specifically crossed with or selected for its dominant Thai landrace characteristics. It emphasizes the "racy" sativa traits of the Thai side.
Generally, no. This strain is a "non-washer." Its trichomes are designed for terpene protection in tropical climates rather than mechanical separation. It is best enjoyed as cured flower or through solvent-based extraction if concentrates are desired.
Most phenotypes of this clone-only strain require 12 to 14 weeks. Some growers even push it to 16 weeks under lower light intensity to mimic a tropical autumn. Harvesting before week 12 usually results in an incomplete terpene profile and a "racey" but short-lived high.
Thai Neville's Haze is considered a "Master Level" cultivar. Between the 14-week wait time, the massive height stretch, and the sensitivity to overfeeding, it is generally recommended for experienced growers who have mastered environmental control.
