Blueberry is one of the most recognisable fruity indicas in the European catalogue and, among our strains, probably the easiest to identify by aroma alone. At Trikoma Seeds it comes in two versions, feminized and autoflowering, which share lineage and a sweet profile but behave differently: one starts flowering when the photoperiod changes, the other flowers by age. In this guide we compare the two 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 fruity indica and its automatic version
The reference is the feminized Blueberry, which our product page documents as Blueberry from the DJ Short line (F2) worked with our own selection. Its base comes from the Afghan and indica material that was worked in North America in the seventies and eighties, crossed with lines of Thai origin: that is where the compact structure and the sweet profile that made it famous when it arrived in Europe in the nineties come from. The result is an 80% indica, 20% sativa genotype, one of the most indica in our catalogue. Our line comes from our own mother plants, selected and maintained in our seed bank in Barcelona.
Blueberry Auto declares a Ruderalis × Blueberry cross: a ruderalis line, the short-cycle subspecies adapted to high latitudes, is added to the photoperiod-dependent parent. That contribution is what makes it autoflowering: the switch from growth to flowering depends on the plant’s age rather than on the photoperiod change.
The two versions side by side
| Feminized | Auto | |
|---|---|---|
| Genetics | Blueberry (DJ Short line, F2) × in-house selection | Ruderalis × Blueberry |
| Type | Photoperiod | Autoflowering |
| Declared THC | 19–24% | 14–19% |
| Reference cycle | About 60 days of indoor flowering | Flowers by age, regardless of photoperiod |
| Reference yield (indoor) | 750–900 g/m² with a 600W LED | 675–810 g/m² (about 20 plants per 600W LED) |
| Aroma | Blueberry and peach over a sweet, slightly earthy base | Sweet, with a fruity touch |
| Structure | Small, sturdy plant, bluish-toned leaves and thick, very resinous buds | Compact plant of restrained size, with very thick buds |
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 Blueberry: the fruity reference
This is the version that defines the line and the one with the higher declared THC of the two, 19–24%. Its declared indoor flowering is around 60 days; outdoors, the product page places the harvest at the end of September in the northern hemisphere and at the end of March in the southern hemisphere, with 0.5–1.5 kg per plant as a reference. Aroma is what sets it apart: not a generic sweetness, but blueberry with just the right acidity underneath, a peach background that rounds off the whole and a slightly earthy base that comes from its Afghan roots. The product page rates its difficulty as easy, with a small, sturdy plant. It is the natural choice for anyone who wants the original Blueberry with its most defined fruity profile.
Blueberry Auto: the sweet profile without depending on the photoperiod
The automatic version keeps the family’s sweet register, although its product page describes it more simply: sweetness comes first and the fruit follows behind, as a nuance. In structure it keeps the indica character of the original, with a compact plant and very thick buds, and at low temperatures it tends to turn bluish, a trait that depends on the environment and the phenotype. Like every autoflowering strain, it does not need the photoperiod change to flower. In return, its declared THC (14–19%) sits five points below that of the feminized one, and its reference yield, 675–810 g/m², is calculated with about 20 plants per 600W LED. We compare it with the rest of the autoflowering strains in autoflowering strains: size, THC and aroma of the 12 in the catalogue.
Which one best fits your collection?
- If you want the original Blueberry, with the higher declared THC and the blueberry and peach profile: the feminized one.
- If you want the family’s sweet character in a compact plant that flowers by age: the Auto.
- If you want to compare how the family behaves: both together. Formats can be mixed, and each version is available in packs of 6, 100 and 1,000 seeds of a single strain.
- If you are interested in Blueberry as part of an assortment: the Super Mix Índica includes three Blueberry seeds alongside Patagonia, Malquerida and Satan’s Bride, and the Super Mix Auto includes three Blueberry Auto seeds.
Blueberry compared with other indicas in the catalogue
The closest strain is Sweet Madness, a Somango × Critical cross that is 75% indica with a sweet forest-fruit profile: they share the fruity register, but Blueberry adds the peach note and a more earthy base. Among the autoflowering strains, Sweet Madness Auto is the other sweet autoflowering strain, with mango notes and 15–20% declared THC, and Northern Lights Auto is also compact and indica-rooted, but with an earthy, piney profile.
We compare the eight fastest and most compact indicas in the catalogue in classic indicas: the eight fastest and most compact feminized strains, and the differences between seed types in feminized, autoflowering and fast version: what’s the difference. We have the same comparison guide for White Widow, AK-74, Critical Plus, Patagonia, Gorilla, Jack Herer, Total Cheese, Wendy, Sweet Madness and The Palmar.
Frequently asked questions
Do both versions come from the same genetics?
They share the Blueberry lineage and the sweet, fruity profile, and both come from our own mother plants maintained in Barcelona. The Auto also includes ruderalis in its cross, Ruderalis × Blueberry, and that contribution is what makes it autoflowering.
Which one has the higher declared THC?
The feminized one, with a range of 19–24%. The Auto declares 14–19%. These are catalogue ranges for the parent lines, not measurements of every seed.
Does Blueberry Auto always turn blue?
No. Its product page describes a tendency to turn bluish when the plant is exposed to low temperatures. It is a trait conditioned by the environment and the phenotype, not a guaranteed characteristic of every seed.
Is there a Blueberry Fast?
No. Blueberry is available in two versions in the catalogue, the feminized one and the Auto. There is no fast version of this line.
