Amnesia Haze Soma Seeds – Legendary Sativa Power with Award-Winning Genetics · Feminized & Regular Options

Amnesia Haze by Soma Seeds is a legendary sativa-dominant powerhouse that’s claimed first prize at the High Times Cannabis Cup not once, but twice—proving its status as a modern classic. With soaring THC levels, complex citrus-pine aromas, and a mind-expanding high, this strain delivers an unforgettable experience for both growers and connoisseurs.

Struggling with weak sativas that underdeliver?

Ever grown a sativa that promised euphoria but left you with limp buds and a meh high? Or worse—waited 14 weeks only to harvest popcorn with barely any resin?

Most sativas are either too slow, too fragile, or just don’t pack the punch they advertise. They stretch out of control, demand constant attention, and still end up with bland flavor and mediocre effects. And if you’re growing outdoors? Humidity and mold can wipe out your crop before it even ripens.

Amnesia Haze by Soma Seeds flips the script. Born from elite Southeast Asian and Jamaican genetics, this strain combines explosive potency with surprising resilience. It finishes in a manageable 10–12 weeks, produces dense, resin-coated colas, and delivers a high that starts with a burst of creativity and gently melts into deep relaxation—no anxiety, no crash.

Wake up your senses with a citrus-pine explosion

From the first whiff to the final exhale, Amnesia Haze is a sensory journey. Crack open a bud and you’ll catch sharp notes of grapefruit and diesel, layered over a woody, earthy base. When vaporized or smoked, it unleashes a smooth, spicy citrus burst that dances on your palate. This isn’t just flavor for flavor’s sake—it’s the terpene profile of a plant bred to impress. Growers report trichomes so thick they look like powdered sugar, and the high reflects that density: clear-headed, energizing, and perfect for daytime inspiration or social connection.

How to grow Amnesia Haze for maximum resin and flavor

Whether you're growing indoors or out, Amnesia Haze rewards care with massive returns. Start with a stable seedling and give it room to stretch—this sativa can double in size during pre-flower. Use a well-aerated soil mix and avoid overwatering, especially in early veg. For best results, keep your grow space between 22–26 °C with 50–60% humidity.

1. Germinate seeds in a moist paper towel or starter cube at 22–25 °C (71.6–77 °F).
2. Transplant to a 3–7 L pot once roots emerge; upgrade to 11–20 L (2.9–5.3 gal) for final size.
3. Provide 18/6 light cycle during vegetative stage; switch to 12/12 to trigger flowering.
4. Apply light training (LST) early to control height and expose lower nodes.
5. Boost flowering with a quality bloom fertilizer like Terra Flores for denser buds.
6. Monitor trichomes: harvest when mostly milky with some amber for balanced effects.
7. Avoid heavy pruning—this sativa recovers slowly. Focus on airflow to prevent mold.

Grow guide: From seed to harvest

Amnesia Haze thrives with steady care and smart setup. Here’s how to maximize your results.

Quick overview

Photoperiod sativa from Soma Seeds. 10–12 week flower. Medium difficulty. Best in temperate/Mediterranean climates.

Safe start

Launch your grow with strong germination and early root health.

• Soak seeds 12–24h in water at 22–25 °C (71.6–77 °F).
• Use starter cubes or moist soil; keep humidity high.
• Transplant when taproot reaches ~1 cm (0.39 in).
• Boost root development with Pro Roots to reduce shock.

Directed growth

Guide your plant through veg with structure and vigor.

• Use 18/6 light cycle; avoid 24h light to prevent stress.
• Grow in airy soil with composted bark and perlite.
• Top early if desired, but avoid FIM or heavy pruning.
• Apply Pro Organic Grow for steady nutrition.

Flowering by stages

Optimize each phase for resin, density, and flavor.

• Switch to 12/12 light; expect stretch for 2–3 weeks.
• Maintain RH at 40–50%; increase airflow to prevent mold.
• Support branches early—they get heavy.
• Use bloom boosters like Bud Factor X from week 3 onward.

Harvest, drying and curing

Finish strong for maximum potency and smoothness.

• Harvest when trichomes are milky with slight amber for balanced high.
• Flush 7–10 days before harvest to improve taste.
• Dry at 18–22 °C (64.4–71.6 °F) and 50–60% RH for 7–10 days.
• Cure in jars for 2–4 weeks, burping daily.

Frequently Asked Questions

Is Amnesia Haze hard to grow?

It’s medium difficulty—best for growers with some experience. It stretches a lot and needs space, but rewards care with big yields and top-tier resin production.

Does it work well outdoors?

Yes, especially in warm, dry climates. It handles outdoor conditions well and can produce over half a kilo per plant with proper care.

What’s the difference between feminized and regular seeds?

Feminized seeds produce only female plants, ideal for harvest. Regular seeds can produce males, making them perfect for breeding or seed production.

How much yield can I expect indoors?

Expect 35–40 g/m² (1.1–1.3 oz/ft²) in optimal conditions. Organic grows may yield slightly less but offer superior flavor.

Does it smell strong during flowering?

Yes, it has a high odor profile. Use a carbon filter if growing indoors to maintain discretion.

Personal Experience of Pevgrow’s CEO (Alan)

I grew Amnesia Haze outdoors in southern Spain three seasons ago, and it’s still one of my top sativas. I started with feminized seeds, gave them 6 weeks of veg, and let them run in 100% soil. No fancy nutrients—just compost, worm castings, and a bit of bat guano. What blew me away was how fast the calyxes swelled. By week 8, the buds were dense, sticky, and smelled like a grapefruit grove on fire. I harvested in late October, dried slowly, and cured for three weeks. The high? Instant clarity, then a warm, giggly buzz that lasted hours. No paranoia, no crash. If you want a sativa that actually delivers, this is it. My only tip: don’t rush harvest. Let those trichomes go milky—it’s worth the wait.
