Lineage Pure Haze strain

Pure Haze is a mostly sativa hybrid, 80% Sativa / 20% Indica, from crossing Purple Thai with Haze. It carries an earthy, spicy, sweet flavor over a strong, mostly sativa body high.

With a THC of 14% to 22%, it is a great choice for anyone after a happy experience with a good dose of energy.

Origin

Pure Haze hails from a lineage of legendary genetics, drawing on the rich history of Haze varieties and their complex, diverse backgrounds. These genetics have been carefully cultivated and stabilized over decades, a prime example of excellence in cannabis breeding.

As with many Haze strains, Pure Haze was bred from a combination of sativa landraces, including those from Thailand, Colombia, Mexico and South India. That heritage gives it its unique qualities and enduring popularity among sativa enthusiasts.

Pure Haze Strain Sativa or Indica?

Pure Haze is a strongly sativa-dominant strain, 80% Sativa / 20% Indica, known for its uplifting, energizing effects. As a classic Haze, it delivers a potent cerebral high that stimulates creativity and brings a real boost of energy, ideal for daytime use.

This feminized strain embodies the classic Haze experience: a clear-headed, euphoric high. The predominance of sativa genetics gives it a long-lasting, invigorating character, a favorite for anyone after a productive, uplifting effect.

Pure Haze Strain Effects

The effects of Pure Haze are predominantly cerebral, an energizing, euphoric and uplifting experience true to its pure Haze heritage. People often report a surge of euphoria and heightened creativity, making it an ideal choice for social situations or creative work. Many also turn to it for support with anxiety, low mood and sleep.

Alongside the mental lift, it offers just a mild body relaxation that keeps the intense cerebral stimulation balanced and comfortable. That makes Pure Haze versatile for recreational and medicinal use alike. Effects vary from person to person.

Germinating Pure Haze seeds

It is important to germinate your weed seeds carefully if you want to have a healthy harvest from day one. Although there are several methods to germinate our Feminized cannabis seeds, at Blimburn Seeds, we recommend our customers to follow our easy and simple technique. Before removing ourĀ Pure HazeĀ seeds from their packaging, remember that cannabis seeds are alive and delicate. Our hands are full of bacteria that can easily infect seeds and ruin our germination.

Set Up Your Germination Station:Ā Begin by moistening two paper towels with room temperature water. Lay one paper towel on a plate and spread the seeds on it, spacing them about 2 cm apart. Place the second paper towel on top of the seeds, and make sure to remove any excess water from the plate. Cover the setup with another opaque plate and store it in a warm, dark location.

Monitoring: Make sure paper towels are still moist by checking every 4-6 hours and spraying room temperature water. Typically, germination should occur within 24 to 120 hours. Once the seeds have sprouted tap roots, plant them with the roots facing down and cover with about 2 cm of soil. Remember to water the soil regularly by spraying to keep it moist. It may take up to two weeks for the plants to start growing.

Ideal Conditions: Maintain a consistent temperature of 69.8 ĀŗF – 78.8 ĀŗF (21 ĀŗC – 26 ĀŗC) in the germination area. Use purified room temperature bottled water with a pH level between 5.5 and 6.5. Keep the seeds away from light, allowing exposure for less than 1 minute before and during germination. Avoid touching the seeds or applying pressure to them.

Record Keeping: To qualify for the three month germination guarantee, it is necessary to follow all the steps outlined in our germination guidelines. Please do not useĀ alternative germination methods, such as using a water bottle or planting directly into soil. Document the germination process through photography or video, as it will be requested when assessing claims for replacement products.

Pure Haze Seeds Flowering Time

Pure Haze has a longer flowering time than indica-dominant varieties, reflecting its sativa heritage, typically 10 to 12 weeks depending on conditions and phenotype.

Despite the extended flowering, it rewards growers with high yields of resinous, aromatic buds. The patience is well worth it: the end product is a potent, flavorful sativa that delivers an exceptional experience.

How to grow Pure Haze Seeds?

Pure Haze seeds can be grown indoors or outdoors under optimal conditions. The plants are robust, hardy and moderately easy to grow, a tall, vigorous Haze that benefits from some training, though it is always worth guarding against pests. A few methods help retain and enhance the terpenes and flavors of your buds:

  • Use a quality substrate. Perlite, peat or coco coir are ideal for moisture retention.
  • In our customers’ experience with Pure Haze, good technique can increase yields by up to 20%.

For indoor cultivation, we advise wide, vertical spaces and the ScrOG method to obtain a uniform canopy and build up the lower flowers. Feed quality nutrients through the seedling, vegetative and flowering stages. Outdoors, choose a spot with the most direct sunlight; indoors, set up good tents, fabric pots, LED lighting, an air extractor and a carbon filter.

Keep daytime temperatures between 68 and 80 ℉, and night temperatures 7 to 9 ℉ cooler than the day. These plants prefer low humidity: 55 to 60% in the vegetative phase, around 40% in flowering, and down to 30% by harvest.

Outdoors in the northern hemisphere, sow in April for a harvest in November, at about 21.16 oz per plant (600 g). Indoors, the cycle runs 10 to 12 weeks with yields of 1.64 to 1.97 oz/ft² (500 to 600 g/m²).

Ideal Climate for Growing

Pure Haze flourishes in a warm, sunny climate, the kind found in Mediterranean or temperate zones. The optimal range is 70 to 85 ℉ (21 to 29 ā„ƒ), which ensures vigorous growth and healthy flowering while bringing out the strain’s unique aroma and flavor. It adapts to various altitudes but thrives best at lower elevations with abundant sunlight and consistent airflow, with around 15 to 30 inches (380 to 760 mm) of annual rainfall and well-draining soil to keep the roots healthy.

In the United States, ideal states include California, Oregon, Colorado, Nevada, Arizona, North Carolina, Florida and Texas, with the perfect conditions for Pure Haze to reach its full potential. In these areas, growers can make the most of the environment to bring out the strain’s robust genetics for a bountiful harvest.

What does the strain smell like?

The buds of Pure Haze are rock-hard, soaked in resin and often carry a crystalline sheen from the sheer amount of trichomes. On the palate it blends a deep, earthy base with a peppery, spicy edge and a sweet, incense-like finish, the classic Haze character drawn from its Purple Thai and Haze parents.

Pure Haze makes for a smooth, soft smoke and a happy experience with a good dose of energy. Thanks to its heavy resin production, it is also an ideal strain for high-quality extracts and concentrates that capture its earthy, spicy-sweet profile.

If that earthy, spicy-sweet aroma speaks to you, you might also enjoy Mexican Haze, Maui Waui, Hippo High or Scrambler Haze.

Experiencing the strain

With a Medium THC of 14% to 22%, Pure Haze brings an energetic, euphoric and uplifting state with a clear, creative head. It leaves you cheerful and inspired, with a classic Haze cerebral buzz.

It is best enjoyed through the day or afternoon, when its uplifting side shines. A mostly sativa plant with a sturdy main stem that supports its satellite branches, it grows well indoors or outdoors, with a similar production and a higher yield when it gets full outdoor sunshine.

Pure Haze seeds are a mostly sativa strain with a flowering period of 10 to 12 weeks. Feeding the right nutrients at each stage helps develop resinous buds and trichomes.

Pure Haze Strain terpenes

Pure Haze carries a focused five-terpene profile that shapes both its earthy, spicy-sweet aroma and its energetic, euphoric Haze high, with four terpenes doing most of the work.

Terpinolene leads the blend, a sweet, fresh, faintly herbal note typical of classic Haze genetics. It is often linked to an uplifting, clear-headed feel rather than sedation. In Pure Haze it drives the energetic, euphoric daytime character and ties into the strain’s use for low mood.

Caryophyllene brings a warm, peppery spice that defines the strain’s Spicy flavor and adds an earthy depth. It is the one terpene that interacts with the body’s CB2 receptors and is widely tied to calming, tension-soothing properties. Here it balances the lively head and sits behind the strain’s use for anxiety and everyday stress.

Myrcene grounds the profile, a ripe, earthy-musky note with a soft sweetness that gives the smoke its body. It is widely associated with a relaxing quality. In this cultivar it provides the light physical ease that keeps the intense cerebral buzz comfortable and supports the strain’s use for restful sleep.

Linalool rounds things off with a soft, floral note carrying a faint sweetness, widely linked to a calming, stress-easing quality that quiets the mind. It tempers the energetic terpenes just enough to keep the high smooth and supports relief from anxiety.

Rounding out the profile, P-Cymene adds a dry, spicy-herbal accent that echoes the Caryophyllene and completes the strain’s earthy, spiced aroma.
