Critical Plus is our take on one of the most widespread indica families in the European catalogue, and it comes in three versions: feminized, autoflowering and fast version. All three share the compact, indica-dominant Critical base, but they do not have exactly the same cross, the same cycle or the same 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.
One Critical base, three paths
The reference is the feminized Critical Plus, whose documented cross is Critical Bilbo × AK-47. Critical Bilbo brings the indica base, compactness and a relatively short cycle; AK-47 adds hybrid vigour and a spicy edge. The result declares 70% indica and 30% sativa. Our line comes from our own mother plants, selected and maintained in our seed bank in Barcelona.
Critical Plus Fast starts from that same feminized version and adds a ruderalis contribution that shortens flowering without making it automatic. Critical Plus Auto takes a slightly different path: its product page declares Critical Bilbo × AK-74 × Ruderalis. In other words, instead of AK-47 directly, it carries our own AK-74 line, which in turn descends from AK-47 × White Widow.
The three versions side by side
| Feminized | Auto | Fast | |
|---|---|---|---|
| Genetics | Critical Bilbo × AK-47 | Critical Bilbo × AK-74 × Ruderalis | Critical Bilbo × AK-47 with a ruderalis contribution |
| Type | Photoperiod | Autoflowering | Photoperiod, shortened flowering |
| Declared THC | 22–27% | 16–21% | 19–24% |
| Reference cycle | 56–63 days of flowering | Flowers by age · up to about 90 cm tall | 49–56 days of flowering |
| Reference yield (indoor) | 750–900 g/m² with a 600W LED | 675–810 g/m² (about 20 plants per 600W LED) | 675–810 g/m² with a 600W LED |
| Aroma | Sweet, citrus and spicy | Sugary, fruity and earthy, with hash notes | Fresh and intense, with a strong lemon 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.
Feminized Critical Plus: the reference
This is the version that defines the line and the one with the highest declared THC of the three, 22–27%. The product page describes a plant with a contained habit, closed branching and compact buds, wider than they are long, in line with its 70% indica. Its aroma works in three layers: a sweet base, a citrus foreground and, behind them, a spicy note that reveals the AK-47 contribution and sets it apart from a classic Critical. It is the natural choice for anyone who wants the original Critical Plus with the fullest profile.
Critical Plus Auto: compact and independent of photoperiod
The ruderalis contribution makes the switch to flowering depend on the plant’s age rather than on hours of light. The product page describes a short plant that rarely exceeds 90 cm, with a high density of flowers in a small volume. Its aroma is the most complex in the family: sugary, fruity and earthy, with a resinous hash note and a declared flavour of nuts and fruit. It was one of the first autoflowering strains we brought to market and is still one of the most requested in this family. Its declared THC (16–21%) is the lowest of the three.
Critical Plus Fast: the short cycle and the lemon
The fast version keeps the photoperiod behaviour of the feminized one but shortens flowering: 49–56 declared days versus 56–63, about seven days less. In return, its declared THC (19–24%) sits about three points lower. In aroma, the feminized version’s three-layer profile becomes more focused and sharper: fresh and intense, with a strong lemon touch. We compare it with the rest of the fast collection in fast versions: which one flowers first.
Which one best fits your collection?
- If you want the original Critical Plus and the highest declared THC: the feminized one.
- If you are interested in a compact, short autoflowering strain with a complex profile: the Auto.
- If you want the line in a shorter cycle with a citrus profile: 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.
The Critical family in the catalogue
The Critical base also appears in other strains of ours. Malquerida shares Critical Bilbo but crosses it with Northern Lights: it declares the same 70% indica, a shorter flowering (45–50 days) and a fruity profile instead of a spicy one. Sweet Madness combines Critical with Somango, declares 75% indica and a sweet, forest-fruit profile.
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, AK-74, Patagonia, Gorilla, Jack Herer, Blueberry, Total Cheese, Wendy, Sweet Madness and The Palmar.
Frequently asked questions
Do all three versions have the same cross?
Not exactly. The feminized and the Fast start from Critical Bilbo × AK-47. The Auto declares Critical Bilbo × AK-74 × Ruderalis: it carries our AK-74 line, which descends from AK-47, instead of AK-47 directly. All three share the Critical Bilbo base.
Which one has the highest declared THC?
The feminized one, with a range of 22–27%. The Fast declares 19–24% and the Auto 16–21%. These are catalogue ranges for the parent lines, not measurements of every seed.
How much does Critical Plus Fast shorten flowering?
It declares 49–56 days of flowering versus 56–63 for the feminized version, that is, about seven days less. It is still photoperiod-dependent: it starts flowering when the light cycle changes.
Why does the aroma change so much between the three versions?
Because each one distributes the line’s registers differently. The feminized combines sweet, citrus and spicy; the Fast concentrates the citrus into a lemon note; and the Auto, with AK-74 in its cross, adds fruit and an earthy base with hash notes.
