How to Grow Amnesia Lemon Fast Version
Amnesia genetics are famous for two things: a soaring, energetic effect and a long wait to get it. Amnesia Lemon Fast Version fixes the second part. This 55% sativa, built from Skunk Haze #1, Amnesia, and a secret hybrid, keeps the zesty lemon-over-hash character of the line but flowers on a fast photoperiod schedule, wrapping up in 8-10 weeks after the flip while staying at a manageable 4.92 ft.
Below is the complete grow plan for Amnesia Lemon Fast Version seeds from Blimburn Seeds, straight from the official datasheet. If you love haze flavor but your season, your patience, or your electricity bill does not love twelve-week sativas, this cultivar and the rest of the fast-flowering seeds range were bred precisely for you.

The outdoor figure is the quiet star here: 24.69 oz (700 g) per plant from a 1.5 m frame is a remarkable return, and the fast bloom means those buds mature before the worst of the autumn weather, which is exactly the problem Fast Version breeding exists to solve.
Promos & Deals
Amnesia Lemon Fast Version vs. Amnesia Lemon
Blimburn Seeds also carries the standard Amnesia Lemon, so know which one you are buying. Both share the lemon-hash flavor identity and sativa-leaning character that put the name on the map among haze strains.
The Fast Version is a photoperiod plant, not an autoflower: it still waits for your 12/12 light switch indoors or the shortening days outdoors to start blooming. The difference is what happens after that signal: its flowering runs noticeably quicker and more uniformly, so you harvest earlier in the season with less exposure to rain, cold, and late-season mold pressure. For growers in short-summer climates, or anyone who wants haze quality on an indica timetable, the Fast Version is the practical pick; the standard cut remains there for traditionalists who do not race the calendar.
Germination and the Vegetative Phase
Germinate with the paper-towel method at 70-79°F: seeds between damp paper towels on a covered plate, in darkness, with taproots showing in 24-120 hours. Plant half an inch deep in light, well-draining soil, taproot down.
Veg under 18 hours of daily light. Growth is brisk and slightly stretchy, true to the 55% sativa lean, with slender leaflets and long side branches that take training well. Keep veg to 4-6 weeks indoors; the plant gains plenty of size during the post-flip stretch, and the whole point of a Fast Version is not to linger.
Top once above the fourth node and use low-stress training to spread the mains into an open, even canopy. A brief interior defoliation at the end of veg keeps light and air moving through what will soon be a fast-moving bloom phase, where there is less time than usual to correct a crowded canopy.
Growing Amnesia Lemon Fast Version Indoors
Indoors, the routine is standard photoperiod practice at a quicker tempo. Flip to 12/12 when plants reach about half of your target height, and expect a healthy sativa stretch during the first three weeks of bloom before buds start stacking in earnest. From the flip, 8-10 weeks takes you to harvest.
Hold temperatures at 68-81°F with lights on and keep humidity at 50-60% in veg, dropping to 40-45% once flowers form. The buds finish denser than most haze hybrids thanks to the Skunk side, so treat them with indica-level airflow caution in the final weeks. The stretch stays polite enough that a 1.5 m plant rarely embarrasses a normal tent.
Expect around 1.31 oz/ft² (400 g/m²), a solid medium return that the speed more than compensates: two Fast Version cycles can fit in the calendar space of one long-flowering haze run.
Growing Amnesia Lemon Fast Version Outdoors
Outdoors is where this breeding pays off most. In a temperate climate, the accelerated bloom means plants finish early in the season, often weeks ahead of standard sativas, dodging the October storms and gray-mold weather that ruin so many haze harvests. That early finish is what the All Season designation on the datasheet reflects.
Plant in full sun after the last frost in 15+ gallon containers or open soil. Each plant can deliver up to 24.69 oz (700 g) of dried flower, so stake the main branches by mid-bloom; lemon-scented colas are heavier than they look. In damp regions, the early harvest window is your built-in insurance policy, but keep inspecting the thickest buds after rain anyway.
Feeding and Watering
Fast flowering compresses the feeding calendar, so transitions between stages come quicker than you may be used to. Follow the plant, not the bottle.
| Stage | EC | pH | Notes |
|---|---|---|---|
| Seedling | 0.4-0.6 | 6.0-6.5 | Plain water or quarter-strength feed |
| Vegetative | 0.8-1.2 | 6.0-6.5 | Nitrogen-forward, add silica for stems |
| Preflower | 1.2-1.4 | 6.0-6.5 | Transition formula at the 12/12 flip |
| Bloom | 1.4-1.6 | 6.0-6.5 | Phosphorus and potassium forward |
| Flush | 0.0-0.4 | 6.0-6.5 | Final 10-14 days, plain water |
Water when the top inch of the medium dries and let pots lighten clearly between rounds. Because bloom moves fast, introduce the phosphorus-potassium formula promptly at the flip; a Fast Version that spends week two of flower still on veg nutrients leaves yield on the table.
Finish with 10-14 days of plain water. The lemon top note is volatile and precious; a clean flush is the cheapest upgrade you can give it.
Flavor, Terpenes, and Effects of Amnesia Lemon Fast Version
The flavor delivers exactly what the name advertises: bright lemon zest riding over an old-school hash depth, with a sweet finish that softens the landing. Six terpenes from the official profile lead the composition. Terpinolene brings the fresh, lemony-herbal lift at the top, while myrcene, caryophyllene, and humulene build the resinous, lightly spiced hash foundation underneath. Geraniol adds a sweet, rosy warmth and linalool a soft floral sweetness that together account for the sugared edge on the exhale.
Pinene and borneol complete the cast in supporting roles. The effect is classic daytime haze: stimulating, creative, and energetic, arriving fast and staying bright. At 20-22% THC it has real presence without tipping into overwhelming territory, making it a fine companion for projects, social plans, or a long walk. Save the heavy indicas for later; this one is built for the daylight hours.
Harvesting, Drying, and Curing
Check trichomes from week 7 of bloom. For the lively, energetic character this strain is bred for, harvest when most trichomes are cloudy with just 5-15% amber; deeper amber trades sparkle for weight. Outdoors, the fast bloom brings that window weeks earlier than standard haze hybrids.
Dry whole branches at 59-68°F and 50-55% humidity for 7-14 days in darkness with gentle airflow, waiting for stems that snap. Cure in glass for at least three weeks, burping daily early on. The hash base is evident from day one, but the lemon brightness blooms in the jar; patience here is the difference between good and memorable.
What to Do With Your Trim
Haze-family trim carries real resin. Dry-sift it for a zesty kief, wash it into bubble hash, where the hashish flavor genes genuinely shine, or infuse it into olive oil for a lemony kitchen staple. The smaller lower buds also make bright, uplifting material for a rosin press.
Common Problems and Pro Tips
Amnesia Lemon Fast Version is a compact, forgiving grow, but it is a sativa-leaning fast version with a loud aroma, so plan for both.
- Catch it in time: it finishes quick for anything with Amnesia blood at 8 to 10 weeks, so start checking trichomes early so you harvest at the ripeness you want.
- Manage the stretch: as a 55% sativa it reaches up after the flip, so train the tops and give it a little headroom to keep the canopy even and well lit.
- Plan for the smell: its lemon and hashish aroma gets loud in flower, so run a carbon filter if you need to keep the grow discreet.
Expert tip: the big outdoor yield is the quiet star here, and the Fast Version flowers early enough to sidestep short seasons. A slow cure keeps its lemon zest over hashish depth at its best.
Frequently Asked Questions
Is Amnesia Lemon Fast Version an autoflower?
No. It is a fast-flowering photoperiod strain: it still needs the 12/12 light switch indoors or shortening autumn days outdoors to bloom, but it finishes faster once flowering begins. That means you keep full control of the light cycle and the plant’s size while getting a quicker finish.
Is Amnesia Lemon Fast Version indica or sativa?
It is sativa leaning at 55% sativa to 45% indica, from Skunk Haze #1, Amnesia and a secret hybrid. The effect is bright and energetic, while the structure stays compact. That sativa lean still brings some stretch after the flip, so train the tops to keep the canopy even and well lit.
How long does Amnesia Lemon Fast Version take to flower?
Flowering runs 8 to 10 weeks from the 12/12 flip, quick for anything with Amnesia blood. Outdoors it finishes early in the season, well ahead of standard haze hybrids, which makes it a good choice for shorter summers where a full-length haze would not ripen in time before the weather turns.
What is the difference between Amnesia Lemon and the Fast Version?
Both share the lemon-hash flavor and sativa character. The Fast Version flowers faster and more uniformly after the light switch, so it suits short seasons and growers who want quicker turnarounds. The genetics are otherwise very close, so you are choosing mainly on speed and timing here.
What does Amnesia Lemon Fast Version taste like?
Lemon zest over hashish depth with a sweet finish, led by terpinolene, myrcene, caryophyllene, humulene, geraniol and linalool. The aroma is loud, so run a carbon filter in flower, and cure slowly in jars so the lemon and hash notes hold up rather than fading after harvest.
What is the THC level of Amnesia Lemon Fast Version?
The official range is 20 to 22%, a confident medium level that powers its stimulating, creative daytime effect without excess. For growers that means a rewarding, approachable plant where the appeal sits in its lively lemon-hash character as much as in the numbers on the datasheet.
