Amnesia at a Glance

Before you plant anything, it helps to see the full picture in one place. Here is the quick profile for this award-winning, Haze-driven sativa, taken straight from the strain’s grow data.

These are feminized seeds, so every plant flowers female and you skip culling males. Its 70% sativa lean places it firmly among the sativa seeds, while its strong harvest earns it a spot with the high-yielding seeds. As the original Amnesia Haze, it is a cornerstone of the wider family of Haze strains.

How to Germinate Amnesia Seeds

A healthy harvest starts at germination. The paper towel method is hard to beat: fold the Amnesia seeds inside two damp sheets, slide them between two plates, and keep them somewhere dark at 70 to 79°F. A taproot usually appears in two to five days.

Once the taproot is a few millimeters long, move each seed root-down about 1 cm deep into a small pot of light, airy medium. Keep it lightly moist rather than soaked, hold humidity around 65 to 70%, and give soft light while the first true leaves open. Its vigorous Haze genetics make for a fast, dependable seedling.

Starter tips

• Use plain, lightly pH-balanced water (pH 5.5 to 6.5) for the first week.
• Keep seedlings warm and humid, but never waterlogged.
• Hold off on nutrients until the second set of serrated leaves appears.

Growing Amnesia in the Vegetative Stage

As a photoperiod plant, you control the veg stage with the light schedule. Keep Amnesia on 18 hours of light a day for as long as you want it to grow, aim for day temperatures of 68 to 79°F, and hold humidity around 50 to 60%. It suits a temperate climate, so steady, moderate conditions work in its favor. As a 70% sativa it grows tall and lanky with open internodal spacing, so plan for a plant that keeps reaching.

This is the stage to shape the plant. Because Haze sativas stretch, topping early and using low-stress training to pull the branches outward keeps the canopy even and the height in check, especially indoors. A shorter veg before you flip helps manage the stretch, and a little support for the long branches pays off once the buds fill in.

Its reaching structure and October finish make it versatile both indoors and out:

• Temperate outdoor plots: its October harvest fits regions with warm summers and a dry early autumn.
• Mediterranean-style gardens: plenty of sun and space let it stretch out and fill its long colas.
• Indoor tents: keep veg short and train hard, as its sativa stretch will otherwise test the height of a tent.

Flowering and Buds of Amnesia

Indoors, flip Amnesia to a 12/12 light cycle to trigger flowering, which runs 8 to 10 weeks. Outdoors it ripens through October. As a Haze sativa it shows a significant stretch in the first weeks after the flip, so leave headroom, then forms long, resinous, spear-shaped colas.

Through bloom, drop humidity to 40 to 45% and keep air moving so the long flowers stay clean. The buds build a fruity aroma over a dry, woody base with the distinctive incense-like, spicy edge that made Amnesia Haze famous, bright and resinous.

At 15 to 20% THC it sits in the medium range, giving an energetic, euphoric and giggly effect, a lively, sociable lift with the clear-headed character that defines a classic Haze.

Common Problems and Pro Tips

Amnesia is beginner-friendly, but its sativa stretch and bright aroma point to a few things worth watching.

• Manage the stretch: as a 70% Haze sativa it can nearly double in height after the flip, so keep veg short and train early to stay within your space.
• Be patient with Haze: at the longer end of 8 to 10 weeks, wait for the trichomes rather than the calendar so the potency and resin fully build.
• Control the smell: its fruity, incense-like nose is carrying in flower, so a carbon filter is close to essential indoors if odor matters.

Expert tip: this award-winning Haze rewards a clean grow. Train hard in veg to tame the sativa stretch, and dry and cure slowly so the bright fruit and spicy incense hold up over its woody base.

Aroma, Flavor and Effects

The nose is bright and distinctive: a sweet, fruity lift up front over a dry, woody base, with the unmistakable incense-like, spicy edge that is the signature of Amnesia Haze. It is an energetic, uplifting profile rather than a heavy or dessert-sweet one.

The flavor follows the nose, sweet fruit and dry wood with a spicy, incense-like finish. On the effect side it is energetic, euphoric and giggly, a lively, sociable lift. Because THC runs a moderate 15 to 20%, it stays rounded and approachable despite its Haze liveliness.

Dominant terpenes

Amnesia carries a bright, layered terpene profile. Myrcene lays down an earthy, fruity base, Valencene adds a sweet, fresh fruity lift, Caryophyllene a warm, peppery spice, Humulene a dry, woody depth, Pinene a sharp pine note, and Phellandrene a minty, peppery-herbal edge behind its incense character. A supporting cast of Borneol, Eucalyptol and Phytol rounds out its fruity, incense and woody profile with cool, camphor-like undertones.

Nutrient Schedule

Treat the figures below as a starting map, not a rulebook. As a vigorous, high-yielding Haze sativa Amnesia is a steady feeder, so read the plant first: tip burn means back off, while pale, slow growth means it wants a little more. All values use EC.

Keep the pH around 6.0 to 6.5 in soil and 5.5 to 6.0 in hydro so the roots can actually take up what you feed.

What to Do With Your Trim: Extracts and Hash

Amnesia builds a solid coat of resin, so its trim is worth keeping rather than tossing. The sugar leaves you take off while manicuring hold trichomes and suit Ice Water Hash, where cold water and agitation separate the resin heads into a clean, solventless concentrate. Pressing that hash into rosin keeps the bright, fruity Haze flavor intact, or you can run a solvent extraction if that is your setup. The bare stems will not extract, but chopped and composted they feed organic matter back into the soil for your next grow.

Harvesting, Drying and Curing Amnesia

Timing the harvest comes down to the trichomes. Grab a loupe and watch the heads turn from clear to milky white; a scattering of amber signals peak ripeness. Indoors this lands 8 to 10 weeks after the flip, and outdoors the plants are ready through October.

After the cut, hang the branches in a dark room at 59 to 68°F with humidity near 50% and gentle air movement. Slow beats fast: drying over 10 to 14 days protects the fruity, incense and woody aromas that made Amnesia Haze a classic. When the small stems snap instead of bending, move the buds into jars.

Cure in sealed glass, opening the jars daily for the first week to let moisture escape, then easing off as the aroma deepens. Two to four weeks of patience here is where the sweet fruit and spicy, incense-like depth really come together, and it is the step most first-time growers rush.

Frequently Asked Questions

Is Amnesia the same as Amnesia Haze?

Yes, Amnesia is the classic Amnesia Haze, a sativa-dominant cross of Haze and Afghan and a Spannabis 2017 winner. The name is often shortened to Amnesia, but it is the same legendary Haze, known for its energetic, euphoric high and its signature fruity, incense-like aroma.

Is Amnesia easy to grow for beginners?

Yes, Amnesia is beginner-friendly. Its vigorous Haze genetics are forgiving, and it finishes in 8 to 10 weeks. The main thing to plan for is its sativa stretch, so keep veg short, train the plant early, and give the long colas some support as they fill in during flower.

How long does Amnesia take to flower?

Amnesia flowers in 8 to 10 weeks once you switch it to a 12/12 light cycle indoors. Grown outdoors, it is ready through October. As a Haze sativa it stretches hard in the first weeks after the flip, then forms long, resinous colas over that bloom window.
