Purple Amnesia Strain Description
Amnesia Purple is a feminized mostly-sativa hybrid (70% Sativa / 30% Indica) crossed from Purple Kush and Amnesia Lemon. With THC levels between 18%–21% and almost no CBD (0.02%), it delivers an uplifting, energetic high alongside mild body relaxation. Plants grow to about 4.92 ft (1.5 m) and yield 1.31–1.64 oz/ft² (400–500 g/m²) indoors or up to 42 oz/plant (1,200 g) outdoors over an 8–10 week flowering cycle.
Its aroma is a bright blend of citrus, fruity sweetness, and herbal undertones, driven by terpenes such as α-Cedrene, α-Pinene, β-Caryophyllene, Myrcene, and Linalool. Therapeutically, it eases arthritis (Δ³-Carene & Linalool), lifts mood (Caryophyllene & Linalool), and combats fatigue through CB1/CB2 activation. Users describe it as calming, happy, and relaxed.
Growers appreciate Purple Amnesia for its compact size, vivid purple hues, and forgiving genetics ideal for beginners looking for both visual appeal and reliable performance.

Growing Environment
Indoors: Keep daytime temperatures at 70–78 °F (21–25 °C) with a 5°F drop at night. During veg, maintain humidity at 55%–65%; once flowering begins, lower it to 40%–50% to prevent mold and concentrate resin.
Outdoors: Choose a sunny, sheltered spot with well-draining soil enriched with compost or worm castings. Ensure at least six hours of direct sun daily and protect from strong winds with fences or hedges. In cooler regions, a greenhouse or hoop house can extend the season and maintain ideal temperatures.
Good airflow is vital: use oscillating fans indoors and space outdoor plants at least 3 ft (1 m) apart to minimize disease and pest risks.
Setting Up Your Grow Space
Purple Amnesia Strain Indoor Cultivation
Use a 4×4 ft grow tent with reflective Mylar. Hang full-spectrum LEDs on an 18/6 cycle for veg, then switch to 12/12 for bloom. Install a carbon-filtered exhaust and oscillating fans to control temperature, humidity, and odor.
Plant in 3–5 gal pots filled with a light, airy soil mix (pH 6.0–6.5) amended with perlite. Start directly in final pots to avoid transplant shock. Automate climate and light schedules with digital controllers for consistency.
Monitor with a thermometer/hygrometer and, if desired, supplement CO₂ (e.g., CO₂ bags) during veg to boost growth.
Purple Amnesia Strain Outdoor Cultivation
Plant after the last frost in raised beds or large fabric pots. Mix native soil with compost and perlite for drainage. Space plants 3–4 ft apart for airflow and light penetration. Stake heavy branches early to prevent wind damage.
Water deeply when the top inch of soil dries, then allow a slight dry-down to encourage strong roots. Mulch to retain moisture and suppress weeds. Use shade cloth during heat spikes and temporary covers in heavy rain.
Apply worm-cast tea every two weeks to enhance microbial life and plant resilience.
Seed Propagation and Germination
Soak seeds in distilled water for 12–24 h to soften the shell. Place between damp paper towels at 75–80 °F (24–27 °C) until taproots emerge (24–48 h). Plant each seed taproot-down ½ in into starter mix and cover with a humidity dome.
Provide 18–20 h of gentle light until true leaves appear. Remove the dome gradually over 3–4 days to acclimate seedlings to ambient humidity and airflow.
Mist lightly rather than flooding the soil to avoid damping-off and label each plant to track phenotype differences.
Purple Amnesia Strain Vegetative Phase
Maintain an 18/6 light schedule with LEDs or CFLs 18–24 in above the canopy. Feed a nitrogen-rich nutrient (N-P-K 3-1-2) at half strength weekly. Apply low-stress training (LST) in weeks 2–3 to develop a flat canopy and maximize bud sites.
Keep temps at 70–78 °F and humidity at 55%–65%. Introduce beneficial microbes or kelp foliar sprays early to strengthen roots. Prune shaded lower foliage to improve airflow and energy focus.
Monitor pH and EC regularly: keep pH 6.0–6.5 and EC 1.2–1.8 mS/cm to prevent nutrient issues.
Purple Amnesia Strain Flowering Phase
Switch to a 12/12 cycle to induce bloom. Use a flowering nutrient high in phosphorus and potassium (N-P-K 1-3-2). Reduce humidity to 40%–50% and maintain temps at 65–75 °F to promote resin and terpene development.
In week 4 remove large fan leaves (“lollipopping”) to expose bud sites. Support heavy colas with soft ties or netting as they swell in weeks 6–8. Begin flushing with plain water in the final week to enhance aroma and smoothness.
Monitor trichomes with a loupe harvest when 70%–80% are cloudy with some amber for peak potency.
Fertilization and Nutrition
Veg (weeks 1–4): N-P-K 3-1-2. Early bloom (weeks 5–7): N-P-K 1-3-2. Late bloom (weeks 8–10): N-P-K 0-3-3. Include calcium, magnesium, and trace elements as needed. Flush in the last week.
Enhance soil with organic amendments worm castings, bone meal, kelp meal to support microbes and improve terpene expression. A foliar seaweed spray early in bloom can boost bud set.
Pest & Disease Control
Inspect daily for spider mites, aphids, and thrips. At first signs, apply neem oil or insecticidal soap, covering leaf undersides. Use yellow sticky traps to catch flying pests.
Ensure strong airflow to prevent powdery mildew and bud rot. Avoid overhead watering during flowering. Quarantine new plants for 7 days before adding them to the main grow.
Harvesting & Curing
Harvest when 70%–80% of trichomes are cloudy with some amber. Cut branches, trim fan leaves, and hang upside-down in a dark, ventilated room at 60–70 °F and 50% RH. Rotate every 2–3 days for 7–10 days until stems snap.
Trim buds and jar loosely in glass containers up to 75% full. “Burp” jars 5–10 min daily in week 1, then weekly for 2–4 weeks. Use humidity packs to maintain 60%–62% RH.
Post-Harvest: Drying, Curing & Storage
After drying, trim final sugar leaves and jar buds with humidity packs. Continue burping daily for one week, then weekly for 2–4 weeks. Maintain 60%–62% RH to lock in terpenes and cannabinoids.
Store jars in a cool, dark place at 60–65 °F (15–18 °C). Avoid light and temperature fluctuations. For long-term storage, add desiccant or RH regulators to preserve quality for months.
Troubleshooting Common Issues
Nutrient Issues: Yellow leaves signal nitrogen deficiency; dark burnt tips signal overfeeding. Correct by adjusting doses or flushing with pH-balanced water, then resume at half strength.
Environmental Stress: Heat causes leaf curl; light burn bleaches leaf tips. Raise lights, improve ventilation, and keep temps below 80 °F. Use a humidifier if RH falls below 40%.
Watering & pH/EC: Overwatering droops plants; underwatering wilts them. Water only when top 1” of soil is dry. Aim for pH 6.0–6.5 and EC 1.2–1.8 mS/cm, adjusting with pH up/down or diluting nutrient solution.
