Amnesia Haze – detailed profile

Genetics and history

Amnesia Haze is a complex sativa hybrid with extraordinarily diverse genetics – combining South Asian indica, Jamaican sativa, Laotian lineage, and Afghan-Hawaiian genes. The variety emerged in the Dutch cannabis scene of the 1990s, when breeders aimed to create the most potent haze variety with maximum cerebral effect. The result more than fulfilled this goal – the effect is so intense that the name "Amnesia" is hardly an exaggeration.

The variety won the Cannabis Cup in 2004 and 2012, confirming its position among the elite of haze genetics. In Amsterdam's coffeehouses, it continues to rank among the most sought-after items, and in the Dutch environment it is considered one of the defining varieties of the entire haze lineage.

Growing tips

Amnesia Haze is designed for experienced growers. The long flowering period (10–12 weeks) places demands on patience as well as energy costs. Indoor plants regularly exceed 180 cm in height, so in smaller growing spaces, topping and aggressive LST (Low Stress Training) are not optional methods but a necessity.

Nutrient uptake is above average, especially in the late flowering phase. Gradual increases in phosphorus and potassium doses are recommended from week 6 onwards, with nutrient burn being fairly common with this variety. Optimal temperature ranges between 22–28 °C – higher values within the physiologically acceptable range support terpene production, particularly terpinolene. Amnesia Haze responds favorably to supplemental CO2 enrichment, which can further increase yield. Patience pays off – well-managed indoor plants yield up to 650 g/m².

Effect and medicinal use

The Amnesia Haze effect is markedly cerebral and in more sensitive users can border on a psychedelic experience. After the onset, which arrives quickly and noticeably, a wave of euphoria, mental energy, and heightened perception follows. Thinking accelerates, creativity increases, and sensory perceptions become more intense. This state persists unusually long – 2 to 3 hours of pure sativa stimulation without notable body sedation.

From a medicinal perspective, it finds application in depression, chronic fatigue, states associated with low motivation, or ADHD. The strong cerebral effect can support concentration in some users, while others may find it overwhelming. The combination of high THC and dominant terpinolene is not suitable for those prone to anxiety – these compounds can deepen anxiety.

Super Lemon Haze – detailed profile

Genetics and history

Super Lemon Haze (SLH) comes from Green House Seeds and was created by crossing Lemon Skunk and Super Silver Haze. The variety achieved singular success by winning the Cannabis Cup in consecutive years – 2008 and 2009. This result at the most prestigious cannabis competition confirmed it to be an extraordinary combination of taste, potency, and accessibility.

SLH inherits the characteristic lemon terpene profile from Lemon Skunk and strong sativa effect with high potency from Super Silver Haze. The result is a variety that functions as a more refined and tastier alternative to purebred haze varieties – without losing what users seek most in sativas.

Growing tips

Super Lemon Haze is one step friendlier to the grower compared to Amnesia Haze. Plants reach heights of 120–180 cm and flower faster – 9 to 10 weeks. Still, this variety cannot be called undemanding; sativa dominance brings characteristic stretching during the photoperiod switch, and height control remains an important part of care.

SCROG (Screen of Green) is an established method that evenly distributes shoots under the light and maximizes space utilization. SLH responds well to organic growing – compost tea and mycorrhizal fungi demonstrably support terpene production, particularly limonene. Harvest timing plays a key role with this variety: the ideal moment arrives with a predominance of milky trichomes with a small amount of amber. Overripe harvest suppresses the energizing component of the effect and shifts it toward heavier relaxation.

Effect and medicinal use

SLH offers an uplifting, energetic, and creative experience with a significantly more approachable character than Amnesia Haze. Users regularly describe feelings of happiness, spontaneous laughter, mental lightness, and clear thinking. The indica component (30 %) adds subtle body relaxation, which rounds out the effect and prevents an overly stimulating progression.

Medicinally, SLH is used for depression, chronic stress, fatigue, and lack of motivation. Limonene as the dominant terpene contributes to uplifting and mood-enhancing effects, and its influence is better documented by research than less common terpenes. For users sensitive to anxiety, SLH is a significantly better choice – the balanced effect with indica dampening reduces the risk of unpleasant states associated with purely sativa varieties.

Direct comparison – where each variety wins

Potency (THC): Amnesia Haze leads slightly (20–25 % compared to 19–24 % for SLH). However, the numbers alone don't tell the whole story – Amnesia is more intense and psychedelic in character, while SLH offers a more manageable effect.

Flowering time: Super Lemon Haze wins unequivocally. The difference of one to two weeks translates into energy consumption, space capacity, and overall cultivation cycle demands.

Yield: Amnesia Haze achieves higher ceiling yields (up to 650 g/m²), but SLH offers a more favorable yield-to-flowering-time ratio – a practically relevant criterion when comparing overall efficiency.

Growing ease: SLH is more accessible in every respect – smaller height, shorter flowering, greater tolerance for errors by intermediate growers.

Flavor profile: SLH wins with its distinctive, fresh lemon profile among users who appreciate clear and intense taste. Amnesia Haze is terpenically more complex but less straightforward.

Suitability for daytime use: SLH is the better choice for regular daytime consumption – it stimulates without excessive overwhelming. Amnesia Haze can disrupt performance in situations requiring attention or fine motor control due to its intensity.

Accessibility for less experienced users: SLH unequivocally. Amnesia Haze can trigger unpleasant states of excessive cerebral stimulation or anxiety in inexperienced users.

Frequently asked questions

Is Amnesia Haze suitable for beginners?

Neither from a growing nor from a user perspective is Amnesia Haze suitable for beginners. Cultivation requires experience with height management, handling long flowering, and precise nutrient dosing. The effect can be too intense for inexperienced users and under unfavorable conditions trigger anxiety states.

What is the main flavor characteristic of Super Lemon Haze?

Super Lemon Haze is characterized by dominant lemon and lime aroma with notes of sweetness and freshness. The taste upon consumption is distinctly lemony with subtle earthy accents in the finish. Its high limonene content ranks it among the most readily identifiable and popular haze varieties from a sensory profile perspective.

How long does the Amnesia Haze effect last?

The Amnesia Haze effect persists unusually long – typically 2 to 3 hours of intense cerebral stimulation, then gradually fades without notable body heaviness. When consumed as edibles, the effect can last significantly longer. Amnesia Haze ranks among the longest-acting varieties available on the market in this regard.

Can I shorten the Amnesia Haze flowering time?

Some growers deliberately harvest earlier – when milky trichomes predominate, the effect is more energetic, though less complex. An alternative is selecting an autoflower version of Amnesia Haze, which flowers much faster and independent of photoperiod. The compromise involves slightly lower yields and typically weaker potency compared to the feminized photoperiodic version.

Which variety better tolerates cooler Central European conditions?

Both varieties are heat-loving sativas with preference for stable, warm weather. Super Lemon Haze has a practical advantage due to its shorter flowering time – outdoor harvest occurs one to two weeks earlier, reducing the risk of late autumn rains, mold, and temperature drops. For outdoor growing in Central Europe, SLH is therefore the more reliable choice.
