AK-74 is one of Trikoma Seeds’ own lines and, like White Widow, it comes in three versions: feminized, autoflowering and fast version. All three share the fresh, fruity character of the family, but they differ in what triggers flowering, in declared THC and in some nuances of aroma. In this guide we compare the three using the data on their product pages, so you can see what changes from one to another and which one best fits your collection.
A family with White Widow inside
The base of the family is the feminized AK-74, whose documented cross is AK-47 × White Widow: two of the most repeated genetics in the European catalogue since the nineties. Our line comes from our own mother plants, selected and maintained in our seed bank in Barcelona, and the Auto and Fast versions start from that same selection.
The interesting part is the split: AK-74 declares 60% sativa and 40% indica, exactly the reverse of its parent White Widow (60% indica). And compared with the earthy profile of the Widow family, AK-74 is fresh and fruity. From there, each version changes what makes the plant flower: the feminized one flowers when the light cycle changes, the Auto by age, and the Fast still depends on light but with a shorter flowering.
The three versions side by side
| Feminized | Auto | Fast | |
|---|---|---|---|
| Genetics | AK-47 × White Widow | Ruderalis × AK-74 | AK-47 × White Widow with a ruderalis contribution |
| Type | Photoperiod | Autoflowering | Photoperiod, shortened flowering |
| Declared THC | 24–29% | 15–20% | 21–26% |
| Reference cycle | 60–65 days of flowering | Flowers by age, regardless of photoperiod | 53–57 days of flowering |
| Reference yield (indoor) | 700–800 g/m² with a 600W LED | 630–720 g/m² (about 20 plants per 600W LED) | 630–720 g/m² with a 600W LED |
| Aroma | Fresh and fruity | Fresh and fruity | Fresh and fruity, with a spicy, woody touch |
| Structure | Compact and branched, with sturdy stems | Compact, with many medium-sized buds spread out | Compact and branched, like the feminized one |
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.
Feminized AK-74: the reference
This is the version that defines the family and the one with the highest declared THC of the three, 24–29%. Its 60% sativa genotype does not translate into the stretched silhouette of a Haze-line sativa: the product page describes a compact, branched plant that spreads its weight over several thick branches. Its aroma is clean and direct, closer to fruit than to heavy sweetness. It is the natural choice for anyone who wants the original AK-74 and the line’s fullest profile.
AK-74 Auto: independent of photoperiod
AK-74 Auto adds a ruderalis contribution to the line, the short-cycle subspecies that makes the switch to flowering depend on the plant’s age rather than on hours of light. It keeps the family’s fresh, fruity register on a compact structure, with many medium-sized buds spread across the whole plant instead of a single dominant cola. Its declared THC (15–20%) is the lowest of the three. It is the version for anyone looking for the AK-74 lineage in an autoflowering format.
AK74 Fast: the feminized one with a shorter cycle
AK74 Fast remains photoperiod-dependent, but a ruderalis contribution in its ancestry, backcrossed towards the feminized line, shortens flowering without making it automatic: 53–57 declared days versus 60–65, about seven or eight days less. In return, its declared THC (21–26%) is somewhat lower than the feminized version’s. In aroma it adds something the feminized one does not have: a spicy note and woody touches behind the fruit. It suits anyone who wants the feminized character in a faster cycle. If you are curious about how this kind of version is obtained, we explain it in fast version: what really changes compared to the original strain.
Which one best fits your collection?
- If you want the original AK-74 and the highest declared THC: the feminized one.
- If you are interested in a compact autoflowering strain that does not depend on photoperiod: the Auto.
- If you want the feminized character with a shorter cycle and a spicy nuance: the Fast.
- If you want to compare how the family behaves: all three together. Formats can be mixed, and each version is available in packs of 6, 100 and 1,000 seeds of a single strain.
AK-74 in other crosses in the catalogue
AK-74 also appears as a parent in other strains of ours. Critical Plus Auto carries it in its cross alongside Critical Bilbo and ruderalis, with a sweeter, earthier profile. The Palmar Auto starts from AK-74 and Power Plant and declares 14–19% THC.
If you want to go deeper into the differences between the three seed types, we explain them in feminized, autoflowering and fast version: what’s the difference. And to see how other families in the catalogue compare, we have the same guide for White Widow, Critical Plus, Patagonia, Gorilla, Jack Herer, Blueberry, Total Cheese, Wendy, Sweet Madness and The Palmar.
Frequently asked questions
Do all three versions come from the same genetics?
Yes. All three come from the same selection of AK-74 mother plants in our seed bank. The Auto and the Fast also include a ruderalis contribution, which makes the Auto autoflowering and in the Fast only shortens flowering.
Which one has the highest declared THC?
The feminized one, with a range of 24–29%. The Fast declares 21–26% and the Auto 15–20%. These are catalogue ranges for the parent lines, not measurements of every seed.
How much does AK74 Fast shorten flowering?
It declares 53–57 days of flowering versus 60–65 for the feminized version, that is, about seven or eight days less. It is still photoperiod-dependent: it starts flowering when the light cycle changes.
How is AK-74 related to AK-47 and White Widow?
AK-74 is a documented cross of AK-47 × White Widow. It inherits the reputation of both, but with a 60% sativa split and a fresh, fruity profile that sets it apart from White Widow’s earthy character.
