Where the Blueberry AK strain comes from
Two famous parents sit behind this cross. Leafly describes Blueberry AK as a cross of indica-dominant Blueberry with sativa-dominant AK-47.
Several breeders have made this cross over the years, which is why the name turns up on menus in more than one form.
Both parents carry long records. Blueberry came out of DJ Short’s landrace work from the late 1970s, and it won Best Indica at the 2000 High Times Cannabis Cup.
AK-47 is the other side: a mostly sativa Serious Seeds strain built from Colombian, Mexican, Thai and Afghani genetics, with a long list of cup placements behind it.
Put together, the child reads balanced on paper and indica-leaning in this tank. Myrcene, pinene and limonene are the terpenes listed for it.
Our take on the Blueberry AK cart
The berry is jammy rather than candied, which we prefer. Behind it sits something dusty and peppery, the AK half showing up.
Effects arrive in the body first. Shoulders and jaw let go, and the head stays clear enough to follow a film.
Honest limit: this is not a knockout cart. Buyers who want to be flattened should look at Cookies Kush instead, since Blueberry AK keeps you awake and comfortable rather than asleep.
What 1100mg buys you in a cart
The number is the oil in the tank, not the punch in one draw. Strength per pull comes from the distillate, and that holds steady to the last of it.
Most evening users get weeks out of a tank. Short draws stretch it further than long ones.
What Willo leaves out of the tank
The spec is short by design. No Vitamin-E acetate. No PG. No VG. No MCT.
Those last three are thinning oils. They stretch a tank and smooth the pull, and they dull fruit flavours on the way.
- In: THC distillate, plus terpenes for taste.
- Out: the acetate and all three thinners.
- Cost: a thicker oil that needs a second to move.
Berry is the flavour that suffers most from thinners. Leaving them out is the reason this one still tastes of jam.
Flavour, draw by draw
The first pull is fruit. The middle is dusty and sweet. The exhale turns peppery.
Myrcene brings the ripe, soft weight. Pinene adds a sharp green note. Limonene lifts the whole thing at the end.
Those three come from Leafly’s listing for the strain, and they match what we taste.
How to use a Blueberry AK 510 thread cartridge
Screw the cart onto a charged battery until it seats. Over-tightening strips threads on both halves.
- Voltage: 2.4-2.6V at the start, adjusted up in small steps.
- Draws: short pulls with a minute of patience between them.
- Berry terpenes cook off first, so low heat protects the fruit.
- Storage: upright, room temperature, out of the sun.
What an indica-leaning cart feels like
Body before head, in a sentence. The lift settles into the shoulders and stays there.
- Onset: within minutes.
- Duration: 1-3 hours.
- Feels like: calm, heavy-limbed, comfortable.
- Best hours: after dinner.
- Level: manageable for most, with tolerance setting the pace.
Newer vapers should stop at one draw and wait. There’s no advantage to stacking pulls in the first five minutes.
Berry carts and the evening slot
Fruit flavours read light, and buyers sometimes read the effect the same way. This one is heavier than it tastes.
We treat it as an after-dinner cart. It pairs with a couch and a screen better than with a to-do list, and the calm builds over the first ten minutes rather than arriving all at once.
Anyone new to indica-leaning carts should plan the evening around it, not the other way round.
Willo, the Toronto brand behind it

Common questions
Is Blueberry AK indica or sativa?
Blueberry AK crosses indica-dominant Blueberry with sativa-dominant AK-47, and sources call the result a hybrid. Willo labels this cart indica, and the effect leans that way — body-first and evening-shaped.
How do I use a 510 cartridge?
Screw it onto a charged 510 battery, start around 2.4-2.6V, and pull in short draws a minute apart. The effect shows up in minutes and fades across 1-3 hours.
Who bred Blueberry AK?
Several growers have made their own version of this cross over the years. The parentage is the settled part: DJ Short's Blueberry, a 2000 High Times Cup winner, crossed with Serious Seeds' AK-47.
