seeds_plant_height=seeds_plant_height=Taller-flowering version that is great for beginners. Resistant, productive and potent indica-dominant plants.

Critical Mass FAST is an indica-dominant variety produced from a cross of Critical Mass 2.0 with an auto strain and subsequently selected for non-autoflowering properties. A great strain for growing outdoors in damp and/or cool conditions and easy to grow, even for the complete novice. Expect high yields with very high levels of THC.

Adapted to outdoor cultivation with its hardiness and resistance, Critical Mass FAST is also grown indoors with great success. Plants are bushy and shrub-like. Indoors, plants grow 90 cm. seeds_plant_height=seeds_plant_height=Tall and take six to seven weeks s to finish flowering. Indoors, yields are approximately 600 gr/m2.

Outdoor plants grow seeds_plant_height=seeds_plant_height=Taller, up to 200 cm, finishing about three weeks quicker than the standard (i.e. non-FAST) version, and will be ready to harvest during September in northern latitudes thereby extending its limit of outdoor cultivability. Each plant can yield 600 gr. of dried buds or even more.

The dominant organoleptic attributes are Skunk-like with a sweet, spicy back-note and a woody finish. THC content is very high at 22% and the effect is very physically relaxing.

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
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.

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.
