How to Grow Amnesia Hypro
Amnesia Hypro is a soaring, citrus-forward, sativa-dominant feminized strain that crosses Amnesia with Neville Haze. It is an 80/20 sativa with a very high 25-30% THC, a zesty citrus, diesel and sweet flavor, and a happy, uplifted effect with a hungry, munchie-inducing edge. A Spannabis winner, it is a classic, energizing haze for growers who want a cerebral, potent sativa.
As a feminized strain, Amnesia Hypro produces only female, flower-bearing plants, so you can skip sexing and remove the guesswork of sorting out males. Every seed goes toward productive, bud-growing plants from the start. You grow it under long days through its vegetative stage, then switch the lights to 12/12 to trigger flowering, which gives you full control over the plant’s final size and its timing.

Growing a Feminized Strain
Amnesia Hypro is a photoperiod feminized strain, which means it flowers in response to the light cycle rather than its age. You keep it under long days, usually 18 hours of light, for as long as you want it to grow and build structure, then switch to 12 hours of light and 12 hours of darkness (12/12) to tell the plant to start flowering. Because every seed grows into a female, there are no males to find and remove, so your whole crop goes toward buds.
That control over timing matters a great deal with a haze-leaning sativa like Amnesia Hypro, which stretches hard once it flips and can nearly double in height. Flip it to 12/12 earlier than you would an indica to keep the final size in check, and use the vegetative stage to top and train it. Spreading the canopy tames its tall frame and keeps the many flowering tops level through its long 10 to 12 week bloom.
Climate and Where to Grow It
Amnesia Hypro favors a warm, tropical climate and thrives both indoors and outdoors where it gets plenty of light and a long, warm season. Outdoors in the Northern Hemisphere it finishes late, around November, because of its extended haze flowering, so it needs a mild autumn to ripen fully. Give its tall, stretchy sativa frame plenty of headroom in a tent or open space outside.
Its yield is solid at around 400-450 g/m² indoors and a generous 400-550 g per plant outdoors with room to grow. As an energetic, uplifting sativa built on true haze genetics, its very high 25-30% THC places it firmly among our high-THC seeds. A Spannabis winner, it also sits among our award-winning cannabis seeds and Spannabis-winning seeds.
That pedigree comes straight from its parents: Amnesia lends the zesty citrus and classic haze punch, while Neville Haze brings soaring, cerebral energy and a long, sativa flowering. Keep temperatures around 68-80°F (20-27°C) and good airflow through flowering, since its airy haze colas appreciate steady movement to ripen clean.
Feeding Schedule (EC Guide)
Amnesia Hypro is a vigorous, fast-growing plant, so feed it steadily but do not overdo the nitrogen, which sativas can be sensitive to. Start light while it is young, build through the vegetative stage, shift toward phosphorus and potassium once it flips into flower, then flush at the end so the zesty citrus and diesel notes come through clean. The ranges below are a starting guide; adjust to your water and medium.
| Stage | EC (mS/cm) | Notes |
|---|---|---|
| Seedling | 0.5-0.7 | Very light feed while roots establish |
| Vegetative | 1.0-1.4 | Build nitrogen gently as the plant stretches |
| Early flower | 1.3-1.6 | Shift toward bloom nutrients (P and K) |
| Full flower | 1.5-1.8 | Peak bloom feed through its long bloom |
| Flush | 0.0-0.4 | Plain water for the final 1-2 weeks |
Flowering and Harvest
Once you flip it to 12/12, Amnesia Hypro takes a long 10 to 12 weeks to finish, typical of a haze-dominant sativa, so it rewards patience. It builds long, resin-flecked, spear-shaped colas that fill out well for a haze, developing a loud citrus, diesel and sweet aroma as it ripens. That extended bloom is the price of a true haze, and the cerebral, flavorful result is worth it.
Yields are solid at around 400-450 g/m² indoors and 400-550 g per plant outdoors where it has room to stretch. Keep the tall colas supported and the canopy even so light reaches every flowering top, feed it steadily through flower, and harvest when most of the trichomes have turned cloudy for a bright, cerebral, zesty effect, or wait for a little amber for a slightly rounder finish.
Drying and Curing
Dry whole plants or branches in a dark room at around 60°F (15-18°C) and 55-60% humidity for 7-14 days, until the thin stems snap rather than bend. A slow, even dry preserves the volatile citrus and diesel terpenes that make Amnesia Hypro so aromatic, and because airy haze buds dry quickly, watch them closely so they do not over-dry and lose that bright, zesty punch.
Then cure the trimmed buds in sealed jars, burping them daily for the first week and letting them settle for three to four weeks. A proper cure is what locks in the zesty citrus and sweet, fuel-like notes and smooths the smoke, turning a freshly dried harvest into the fresh, tangy, classic haze result Amnesia Hypro is known for.
What to Do With Your Trim
Don’t bin the sugar leaves you remove while manicuring. Amnesia Hypro is a fragrant, resinous plant, so its trim is excellent for dry sift, bubble hash or rosin. That citrus-and-diesel aroma and sticky resin make the trim genuinely valuable, turning offcuts into a bright, flavorful concentrate run rather than waste, carrying that zesty haze character into your extracts.
Flavor and Terpenes
Amnesia Hypro leads with a loud, zesty flavor: a bright citrus lift, a sharp diesel edge and a sweet undertone, the classic Amnesia haze profile. It is a tangy, aromatic smoke with a fuel-like kick, and a good cure keeps that citrus-and-diesel character bright in the jar and on the inhale.
Its terpene profile is rich and shapes that freshness. Limonene drives the bright citrus top note, while alpha-pinene adds a crisp, pine-sharp lift and caryophyllene a peppery bite that underlines the diesel. Myrcene forms an earthy base, with linalool, humulene and a cool touch of menthol rounding out one of the more complex, aromatic profiles around.
Effects and Best Use
With its very high 25-30% THC and strongly sativa 80/20 make-up, Amnesia Hypro delivers a powerful, cerebral experience. It is reported as happy, uplifted and hungry, pairing a bright, energetic, talkative head with a munchie-inducing edge that often makes a good meal especially tempting. The soaring sativa character makes it a natural fit for daytime, creative and social use.
That happy, uplifting profile makes it a rewarding strain for creative projects or hanging out with friends, alongside its zesty citrus-diesel flavor. The combination of a true haze high, exceptional potency and a loud, classic taste is exactly why this Spannabis winner remains a favorite among feminized strains.
Common Problems and Pro Tips
Amnesia Hypro is forgiving and beginner-friendly, but its sativa stretch and long flowering are the two things to plan for. It can nearly double in height after the flip, so flip to 12/12 earlier than you would an indica and keep plenty of headroom. Top it and train it during the vegetative stage, while it still has time to recover, to spread the canopy and even out the many flowering tops.
Because it leans haze, patience matters: give it the full 10 to 12 weeks rather than harvesting early, and keep the airflow steady, since its airy colas benefit from good movement. Go a little easy on the nitrogen, as sativas can show burn, and support the taller branches as the long colas firm up toward the end.
As a pro tip, protect what makes Amnesia Hypro special, its loud citrus-and-diesel aroma. Those terpenes are volatile, so avoid excessive heat late in flower, dry it slowly and cool, and give it a full three to four week cure with a proper plain-water flush beforehand. Save the fragrant trim for concentrates, and harvest when most trichomes are cloudy for a bright, cerebral result.
FAQ
Is Amnesia Hypro a feminized strain?
Yes. Amnesia Hypro is a photoperiod feminized strain, so every seed grows into a female, flower-bearing plant and you never have to sex or remove males. You grow it under long days through the vegetative stage, then switch the lights to 12/12 to trigger flowering, which gives you full control over the plant’s size and when it finishes.
How long does Amnesia Hypro take to flower?
Amnesia Hypro is a longer finisher, taking about 10 to 12 weeks in flower once you switch it to a 12/12 light cycle, which is normal for a haze-dominant sativa. Outdoors in the Northern Hemisphere it is typically ready to harvest around November. That extended bloom is what gives it its loud, classic haze flavor and cerebral potency.
How much THC does Amnesia Hypro have?
Amnesia Hypro is a very potent strain, testing from about 25% up to 30% THC depending on the phenotype and how it is grown. Combined with its strongly sativa 80/20 genetics, the result is a happy, uplifted, energetic effect with a hungry edge. Because the potency is so high, it is well worth dosing carefully, especially if you are newer to strong strains.
Does Amnesia Hypro grow tall?
Yes, it leans tall. As a haze-dominant sativa Amnesia Hypro stretches hard after the flip and can nearly double in height, reaching around 1.5 m or more. Flip it to 12/12 earlier to control the final size, keep headroom in your tent, and top or train it during veg to spread the canopy and even out the tops.
What does Amnesia Hypro taste like?
It has a loud, zesty flavor: a bright citrus lift, a sharp diesel edge and a sweet undertone, the classic Amnesia haze profile. Limonene drives the citrus, alpha-pinene a crisp pine note and caryophyllene a peppery bite behind the diesel. A proper cure keeps that citrus-and-diesel character bright on the inhale.
Has Amnesia Hypro won any awards?
Yes. Amnesia Hypro is a Spannabis winner, a strong marker of its quality, flavor and potency. That award-winning pedigree comes from its Amnesia and Neville Haze parents, and it is reflected in the loud citrus-diesel aroma, soaring cerebral high and very high THC the strain is known for.
