Fast-finishing hybrid strain with XL yields and THC content of almost 25%.

GMO (Garlic Cookies)Think Fast

Fast-finishing hybrid strain with XL yields and THC content of almost 25%.

GMO Fast is a so-called ‘fast’ feminised seed version of the Garlic Cookies strain, sometimes known as GMO (Garlic Cookies). Our search for a super potent and pungent GMO strain led us to create this unique fast cultivar. For this, the Dutch Passion geneticists used a very potent GMO clone that was crossed with our classic Think Fast strain.

The result is a fast, stable and potent photoperiod cannabis seed variety with a completely game-changing terpene profile. Most GMO Fast plants have the unmistakable and unique savoury, onion/garlic aroma profile. The THC levels of this feminised cannabis seed variety are very high and will usually be around/above 20%. Initial lab results indicated THC levels of around 22-23%. And all that in a very rapid flowering period thanks to the recessive (‘fast’) autoflower genetics. When grown indoors, she will be ready for harvest around 7-8 weeks after flipping the cannabis light cycle to 12/12.

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.
