Haze is among the most popular Sativa strains today. It has dominated the market for years because of its fast-acting high, delicious flavors, and mood-enhancing high. Not to mention, it has significant therapeutic effects that provide comfort to patients suffering from a myriad of maladies.

It is a long-flowerer though. And, for this reason, many seek to shorten its maturation period. It was to this end that the long-running British Colombia Seed Company decided to cross Haze with the Indica-leaning Blueberry. In doing so, it enhanced the Sativa’s flavors and improved its overall growth profile.

Blaze is a potent strain with THC levels that range between 18% to 20%. When used beyond limitation, it can deliver a head-slamming high that overwhelms users. In moderation, however, it can be quite pleasant.

Its onset begins with a rush of euphoria that clears the mind. It uplifts the mood, so users stay upbeat throughout the day. As the cerebral buzz persists, a surge of energy trickles down from the temples and down to the rest of the body. It kneads the muscles to release tension or tightness and undoes any knots without locking one to the couch.

For most enthusiasts, the freedom from physical and mental inhibition is a deeply relaxing and invigorating experience. However, it can also be quite arousing. For this reason, one may use it for an exciting afternoon or night with a loved one.


Blaze has a pungent scent with a fruity profile. Its saccharine overtones lined with trails of sweet lemons, delicious blueberries, and ripe grapes that intensify after breaking apart the buds. Upon combustion, it later turns into a spicy undertone.


Drawing in Blaze’s smoke, users immediately taste its overtones of fruit. It is a blend of blueberries, grapes, and lemon that leave an enticingly sweet but tangy flavor. On the exhale, a spicy aftertaste lingers in the mouth for hours on end.

Adverse reactions

Dry eyes and a cottonmouth are two inevitable reactions to using marijuana especially as the cannabinoids begin to interfere with the body’s natural ability to produce and retain moisture. At times, it is accompanied by a headache. Although mild and temporary, users may manage the dry spell by downing a few glasses of water throughout the day and avoiding any caffeinated or alcoholic drinks.


Its uplifting onset, for example, is a source of comfort to users dealing with chronic stress. It enhances the mood and stabilizes turbulent emotions. Because of this, it is also a source of comfort for patients with mental health issues like anxiety, depression, and PTSD.

THC, when concentrated at high levels, turns into a natural painkiller that relieves aches beginning from the temples. Ironically, it also dulls headaches as much as it causes the condition. At the same time, it appeases inflammation by reducing redness and relieving swelling. In doing so, it prevents the muscles from uncontrollably contracting and causing pain.

The temporary liberation from mental and physical health issues, as well as continuous relaxation, eventually leaves users feeling drowsy. With its sedating properties, the Sativa-dominant bud improves not only the quantity of sleep but also its quality, so one wakes up the next day feeling thoroughly invigorated.


Blaze grows very much like a Sativa. It is lanky with branches and stalks that are thinner compared to its Indica counterpart. Even so, it is significantly sturdier due to the addition of Blueberry. Because of this, growers in the northern hemisphere who are cultivating it in gardens or farms can expect it to flower earlier.

It is much better suited indoors where one can mimic a Mediterranean climate by adjusting growing factors like temperature, lighting, and humidity. However, it will need to be topped early as its height can get out of hand. Keeping its vegetative phase short will help manage its growth spurt while improving light and air circulation in the lower nodes. Removing dying fan leaves as well as branches will also help distribute nutrients better to healthier budding sites.

With that said, the Screen of Green method works best for Blaze. It keeps its height short while evenly distributing light. Pairing it with a medium like hydroponics will hasten its maturation period while improving its yields. Soil is also a good choice as it enhances the overall flavor of buds.

At the moment, Blaze is only available in regular form. As such, growers will have to apply pre-germination techniques like soaking to reduce the chances of growing more than 50% males in a batch. Low-Stress Training techniques also keep the females from turning into hermaphrodites during the flowering phase.

Flowering Time


Blaze has an indoor flowering period of 8 to 10 weeks. Although long, the wait is well worth it as it rewards growers with at least 12 to 16 ounces of buds per square meter.


In the northern hemisphere, Blaze flowers between the second to the last week of October. Although, depending on the weather, it can extend by a week or two more. Once ready for harvest, it yields at least 16 ounces of buds per plant.
