AmnesiaAfghani selection
This version of Amnesia offers enhanced resistance compared with the original Amnesia strain.
Amnesia FAST was created from the cross of an elite Haze cutting with selected Afghani strains. This FAST version has a slightly quicker flowering time and an improved resistance to mould and pests. Amnesia FAST is an easier strain to grow than the original thus offering a range of benefits. It is 80% sativa.
These plants develop fewer lateral branches than the standard version, with production mainly located on the main stem and forming a large cola, good for SoG. Growers should restrict the period of vegetative growth indoors to control its height; outdoors plants can grow to 250 cm.
Indoors, yields are about 450 - 500 gr/m2. Northern latitude harvests will be ready in early October - we do not have figures for yields outdoors yet, but in line with other sativa-dominant strains they are expected to be very good. Buds are dense, thanks to the Afghani influence, and coated in sparkling resin.
Amnesia FAST has a citrus scent with notes of spice and incense. THC content is high at 18% and the effect is euphoric and uplifting.

Early/Fast outdoor timeline
Fast / Early strains keep the photoperiod growth pattern, but they begin flowering earlier and usually finish sooner — helping outdoor growers harvest before late-season weather becomes a problem.
Stage 1
Germination / Early Start
March – April
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
Wait for: long bright days, healthy expansion, strong structure
Watch for: overcrowding, nutrient issues, insect pressure
Stage 4
Flowering
From late July
Wait for: first signs of bloom, good airflow, settled conditions
Watch for: humidity, mould pressure, poor weather
Stage 5
Harvest
From early September
Wait for: ripe trichomes, dense finished flowers, harvest readiness
Watch for: cutting too early, rain, bud rot
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.
