How to Grow Amnesia F1

Amnesia F1 is a 60% sativa-dominant feminized F1 strain, bred by crossing two selected Amnesia parents. It carries a THC level of 15 to 20%, which sits in the medium range, and delivers an energetic, euphoric and giggly effect over a fruity, incense-like and woody flavor. As a first-generation (F1) hybrid it brings strong hybrid vigor and uniform, predictable plants. This guide walks you through the whole grow, from germinating the seeds to the final cure.

It reaches a medium 1.5 m, flowers in 8 to 10 weeks, and finishes outdoors through October with a very high yield. Its F1 vigor and forgiving nature make it a rewarding pick even for first-time growers.

Amnesia F1 at a Glance

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

These are F1 feminized seeds, so every plant flowers female and brings the extra vigor and uniformity of a first-generation hybrid. Its 60% sativa lean places it among the sativa seeds, while its big harvest earns it a spot with the high-yielding seeds. Its Amnesia backbone also makes it a classic in the wider family of Haze strains.

How to Germinate Amnesia F1 Seeds

A healthy harvest starts at germination. The paper towel method is hard to beat: fold the Amnesia F1 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 F1 vigor makes 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 F1 in the Vegetative Stage

As a photoperiod plant, you control the veg stage with the light schedule. Keep Amnesia F1 on 18 hours of light a day for as long as you want it to grow. It is bred for a tropical climate, so it takes the heat well; aim for warm day temperatures of 68 to 82°F and keep humidity controlled, around 50 to 60%, with strong airflow so the warmth does not turn muggy. As a 60% 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 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 big outdoor potential make it versatile, with real presence outdoors:

• Warm outdoor plots: given space and a long, warm season, it can become a large plant and push toward its huge outdoor potential.
• Humid, tropical gardens: it handles warmth well, but keep air moving so its dense buds stay clean in humidity.
• 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 F1

Indoors, flip Amnesia F1 to a 12/12 light cycle to trigger flowering, which runs 8 to 10 weeks. Outdoors it ripens through October. As a 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, which matters all the more in the warm, humid conditions it is bred for. The buds build a fruity aroma over a dry, woody base with a distinctive incense-like, spicy edge, the lively Haze character of its Amnesia parents coming through 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 of a Haze sativa.

Common Problems and Pro Tips

Amnesia F1 is beginner-friendly, but its sativa stretch and tropical preference point to a few things worth watching.

• Manage the stretch: as a 60% sativa it can nearly double in height after the flip, so keep veg short and train early to stay within your space.
• Humidity in the heat: it loves warmth, but keep a fan moving and humidity below 45% late in flower so its dense buds stay clean.
• Support the colas: its long, resinous buds get heavy, so stake or net the branches before they bend.

Expert tip: its fruity-and-incense profile 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 an unmistakable incense-like, spicy edge that is pure 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.

Dominant terpenes

Amnesia F1 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 sativa Amnesia F1 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 F1 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 F1

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 define this strain. 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.
