The faster-finishing relative of Do Si Dos Cookies, this FAST version maintains the high yields and levels of THC that made the original so popular. Gives a long-lasting, relaxing effect.

Do Si Dos Cookies FAST is a potent hybrid strain that is the product of two well-known cannabis varieties, viz. Girl Scout Cookies, a strain
that was stabilised in San Francisco and which is a cross of Florida OG Kush and F1 Durban, pollinated by Face Off, a classic 90s Californian strain,supplying its indica qualities.

Do Si Dos Cookies FAST displays indica-dominant traits. Physically, this strain's structure is quite short with short spaces between the nodes. In addition these plants produce many large, dense flowers concentrated on the central stem, which is then easily able to support the weight of the mature buds. Do Si Dos Cookies FAST reduces the flowering time to a mere 50-55 days when grown indoors, while outdoor harvests should be ready by the third week of Seoptember in northern latitudes. Despite this fast flowering the strain's yield potential remains impressive. Indoors, growers can expect 550 gr/m2.

Do Si Dos FAST's organoleptic properties offer complex flavours and scents. Sweet, earthy, and pine scents dominate. The terpene profile of Do Si Dos Cookies Fast is produced by the terpenes myrcene, nerodiol, ocimene, and pinene. Its high level of THC coupled with its indica-dominance produces a potent yet relaxing, calming and long-lasting effect.

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.

Frequently asked questions
Is this strain suitable for my growing environment?

In theory most strains can be grown outdoors, indoors or in a greenhouse but how well they perform depends on the more exact environmental conditions. This is most important outdoors where climatic conditions can vary widely, so please check the strain information carefully. If your climate is more extreme or growing season shorter you should choose strain that is specifically adapted. Indoor and greenhouse environments can be controlled and made suitable for most strains although space can be a factor for strain that grow very large.

How difficult is this strain to grow?

Growing difficulty varies depending on a strain's resilience, structure and environmental needs. Some strains are more forgiving and better suited to beginners and a range of environmental conditions, while others may require closer control of factors such as light, humidity, temperature and feeding.

What can I expect in terms of cannabinoid content and yield?

Our product information and that provided by suppliers can be an indication of potential levels under optimal conditions, and it should not be assumed that results can be replicated in all conditions.

Is this strain suitable for beginners?

Strains described as beginner-friendly, easy to grow or resilient, in particular Autoflowering Feminised strains, are generally more manageable for less experienced growers. These varieties are often a more reliable starting point than more specialised genetics.
