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
