Our fast collection brings together six strains: White Widow, Gorilla, Black Domina, Critical Plus, Patagonia and AK-74. They all share the same idea, a photoperiod feminized strain with shortened flowering, but they do not shorten by the same amount or start from the same point. In this guide we rank them by declared flowering days and compare what changes in each one against its feminized version, using the data on their product pages.

What a fast version is, in one sentence

A fast version is a feminized strain that still starts flowering when the light cycle changes, but carries a ruderalis contribution in its ancestry, backcrossed towards the feminized line, that shortens flowering without making it automatic. We explain it in more detail in fast version: what really changes compared to the original strain.

The six fast versions, from shortest to longest

Strain Origin line Declared flowering Its feminized version Declared THC Aroma
White Widow Fast Widow Bilbo × Widow BCN 40–49 days 47–56 days 15–20% Earthy, with pine and a spicy touch
Gorilla Fast Chem Sis × Sour Dubb × Chocolate Diesel 43–53 days 50–60 days 22–27% Earthy and diesel, with a sour, citrus edge
Black Domina Fast Cross of four indicas 45–50 days No feminized version 21–26% Intense, earthy, spicy, with hash notes
Critical Plus Fast Critical Bilbo × AK-47 49–56 days 56–63 days 19–24% Fresh and intense, with a strong lemon touch
Patagonia Fast OG Kush × Northern Lights About 53 days About 60 days 15–20% Earthy and sweet, with citrus touches
AK74 Fast AK-47 × White Widow 53–57 days 60–65 days 21–26% Fresh and fruity, with a spicy, woody touch

These are catalogue figures declared for the parent lines, useful for comparing strains with each other; they are not a measurement of every seed or a guarantee of results.

What the data shows

Placed side by side, the product pages reveal three clear patterns:

  • One week less, consistently. In the five fast versions that have a feminized version in the catalogue, declared flowering is about seven days shorter, at both ends of the range.
  • About three points less declared THC. In those same five, the THC range sits about three points below that of the feminized version: for example, Gorilla goes from 25–30% to 22–27%, and AK-74 from 24–29% to 21–26%.
  • The character of the line is kept. Each fast keeps its family’s aroma register: White Widow is still earthy, Gorilla diesel and Critical Plus citrus. What changes is the cycle, not the identity.

The exception is Black Domina Fast, which only exists in this version, so there is no feminized one to measure how much it shortens.

One by one

White Widow Fast: the shortest in the collection

With 40–49 declared days it is the fast version that flowers first. It keeps the earthy, piney profile of the Widow family and declares 15–20% THC. To see how it compares with its other two versions, read White Widow feminized, Auto or Fast.

Gorilla Fast: the highest declared THC

It is the only fast from the USA Strains line and the one with the highest THC range in the collection, 22–27%, with 43–53 days of flowering. Its earthy, diesel profile with a sour edge is the furthest from the rest.

Black Domina Fast: almost pure indica

It comes from a cross of four indica strains and is the fast with the most indica genotype in the catalogue. It declares 45–50 days and an intense, earthy, spicy aroma with hash notes.

Critical Plus Fast: the lemon note

It comes from the indica-dominant Critical Bilbo × AK-47 line and declares 49–56 days versus 56–63 for its feminized version. Its most recognisable trait is a fresh aroma with a strong lemon touch.

Patagonia Fast: sweet and earthy

It keeps the 80% indica of the feminized Patagonia (OG Kush × Northern Lights) and declares about 53 days of flowering. Its earthy, sweet profile with citrus touches is the mildest in the collection.

AK74 Fast: fresh and fruity

It is the fast with the longest cycle, 53–57 days, and the only one with a fresh, fruity profile. It declares 21–26% THC. We compare it with its other two versions in AK-74 feminized, Auto or Fast.

Which one best fits your collection?

  • If you want the shortest cycle: White Widow Fast.
  • If you want the highest declared THC: Gorilla Fast.
  • If you are interested in an almost pure indica: Black Domina Fast.
  • If you prefer a citrus profile: Critical Plus Fast.
  • If you prefer a sweet, mild profile: Patagonia Fast.
  • If you prefer a fresh, fruity profile: AK74 Fast.

All of them are available in packs of 6, 100 and 1,000 seeds of a single strain, and formats can be mixed. You can see them together in the fast versions category. To compare the three seed types, read feminized, autoflowering and fast version: what’s the difference.

Frequently asked questions

Which fast version flowers first?

White Widow Fast, with 40–49 declared days of flowering. It is followed by Gorilla Fast (43–53 days) and Black Domina Fast (45–50 days).

How many days does a fast version save compared with its feminized version?

In our catalogue, about seven days. That is the difference declared by the five fast versions that have a feminized version, at both the short and the long end of the range.

Do fast versions declare less THC than their feminized version?

Yes, in our catalogue their range sits about three points lower. The fast with the highest declared THC is Gorilla Fast, at 22–27%. These are catalogue ranges for the parent lines, not measurements of every seed.

Is a fast version the same as an autoflowering strain?

No. A fast version is still photoperiod-dependent: it starts flowering when the light cycle changes, just with a shorter flowering. An autoflowering strain flowers by age, regardless of photoperiod.
