Sativa-dominant Amnesia Fast Feminised by Seedsman offers potency, fast flowering, and high yield.

Overview

Amnesia Fast Feminised by Seedsman is a sativa-dominant hybrid that offers the best of both worlds: the legendary potency and uplifting effects of Amnesia with a significantly reduced flowering time. A fast-finishing gem, this strain is perfect for cultivators who value efficiency without sacrificing quality. With its impressive yields and signature terpene profile, Amnesia Fast Feminised is an ideal choice for growers and enthusiasts looking for a premium cannabis experience.

Cultivation

Amnesia Fast Feminised is designed with growers in mind, offering an easy-to-manage plant that thrives in various conditions. Its fast flowering period, typically just 8-9 weeks, makes it ideal for those seeking quick results or aiming for multiple harvests in a season. This strain performs well indoors and outdoors, with a moderate height that suits growers with limited space. Its resilience to pests and mold further simplifies cultivation, ensuring a stress-free growing process. With proper care, cultivators can achieve generous harvests of resin-rich buds with minimal effort, making it an excellent option for beginners and seasoned growers alike.

Terpenes & Effects

The terpene profile of Amnesia Fast Feminised is an aromatic blend of citrus, earthiness, and herbal undertones, with dominant notes of limonene, myrcene, and pinene. These terpenes create a refreshing and invigorating aroma, complemented by a subtle sweetness that delights the senses. The effects are quintessentially sativa, delivering a powerful cerebral high that promotes energy, focus, and creativity. As the initial wave of euphoria subsides, a gentle relaxation sets in, providing balance without sedation. Perfect for daytime use, Amnesia Fast Feminised is a go-to strain for those seeking inspiration, positivity, and a clear-headed experience.

Early/Fast outdoor timeline

Fast / Early strains keep the photoperiod growth pattern, but they begin flowering earlier and usually finish sooner β€” helping outdoor growers harvest before late-season weather becomes a problem.

Wait for: warmer days, lower frost risk, stable spring weather
Watch for: cold snaps, excess moisture, slow early growth
Stage 2
Seedling / Transplant
May
Wait for: steady light, mild conditions, protected early growth
Watch for: transplant stress, pests, wind exposure
Stage 3
Vegetative Growth
June – July

Watch for: overcrowding, nutrient issues, insect pressure
Stage 4

Stage 5
Harvest
From early September

Fast / Early strains keep the photoperiod growth pattern, but they begin flowering earlier and usually finish sooner β€” helping outdoor growers harvest before late-season weather becomes a problem.

Indoor Early/Fast timeline

Fast / Early strains are most valuable outdoors, where earlier flowering and shorter bloom times help growers harvest before poor autumn weather. Indoors, their main benefit is a faster flowering phase than photoperiod versions.

Seedsman Genetics Amnesia FAST helped me have my first successful grow as a new grower. I was so proud of my harvest I instantly developed a passion for growing. Quick and easy to grow, great yield with little trimming. Very flavour full. Musky sweet tones with powerful lasting effects. I ordered more of these seeds. πŸ˜βœŒοΈπŸ’š

Very strong growing plant right off the back im thinking these particular seeds must have been hit with steroids the way out jumped over other plants that were planted at the same time or even after it.. Super dominant stand and the fast flower genetics are really starting to show
