Taste & Aroma Profile



The sweet berry flavour of Blueberry, on buds sticky enough that one grower makes finger hash from them.
About Blueberry
Genetics & strain profile
Blueberry Autoflower is a cross between Lowryder #2 and Blueberry, bred by Quebec Cannabis Seeds: a mostly indica autoflower with 20.33% THC and low CBD that keeps the taste and calm high that made Blueberry a favourite. It is one of our best sellers, carries our beginner-friendly and mould tolerant badges, has three grower diaries on GrowDiaries, and its 28 reviews average 4.1 out of 5: “for being mainly indica dominant I was surprised to get six ounces — potent, dense nugs”, “they grew so large compared to ever before, and so sticky I can rub my fingers to make little balls of hash… I have so many jars, some with a quarter pound in each”, and a buyer who checked his seeds on arrival: “fat, deep dark lines, solid, no cracks”, with two of three cracked open overnight. The honest notes: one grower’s first pack did not germinate — we sent another set right away and 4 of 5 came up — and the average is pulled down by a few lower reviews, mostly about germination. Seeds that do not come up are covered by our guarantee; contact us. Our seeds are guaranteed.
How Blueberry Autoflower grows
Because it is an autoflower, it flowers on its own schedule without a change in light hours, and it is ready in 7 to 9 weeks of flowering — about 10 to 12 weeks from seed. We list it at 60 to 90 cm indoors, but pot size and light decide: one grower’s four plants in a 4 by 4 tent went to five feet and “hardly any room”, so a 10 to 15-litre pot keeps it compact and a bigger pot does not. It is tolerant of common pests and mould, though no strain is immune. We list up to 300 g/m² indoors and up to 150 g per plant outdoors; reviewers have gone past that with six ounces from one indoor plant. Plant it in its final pot, keep the light on 18 to 20 hours — one grower keeps his lights 20 inches above the canopy for tighter buds — feed at half strength and keep training to the low-stress kind. Outdoors it even managed a yard with four hours of sun, with tighter buds than the same grower’s indoor run. Started in late May on a Quebec balcony it is done by mid-August. Soak seeds 12 to 24 hours and plant directly in warm, barely damp soil.
Taste, aroma and effect
The sweet berry flavour of Blueberry, on buds sticky enough that one grower makes finger hash from them. The effect is relaxing and calming, strong enough to unwind with at the end of the day without being overwhelming, and at 20% THC it is an evening auto rather than a daytime one. For the photoperiod original, see Blueberry; for a faster photoperiod version, Blueberry Fast Version; for a low-THC berry, CBD Blueberry; for another easy indica auto, Northern Lights Autoflower.

Oh my gosh, I was always complaining I couldn’t grow properly, well this time around with Quebec seed banks amazing seeds..
I grew four plants, because they grew so large compared to ever before, and so sticky, I can rub my fingers to make little balls of hash..
I couldn’t be happier I have so many jars, some with a quarter pound in each, the others are once’s, best grow ever, now without doubt I won’t piss off the misses, complaining about dispensary spending…thank it’s over..
And thank you Quebec Seed Bank for always having best seeds.

Wow, few weeks past the popcorn stage, four plants in 4 by 4 tent, hardly any room they are so big, it’s amazing the plants are ballistic in growth…all five feet high, had to put lights up higher than ever, like to keep lights twenty inches above plants, that way you get really tight buds, lights to close, causes them to be lighter, and Larfy. My experience anyway, still learning , but last three grows showed me I finally learned how to grow in a tent..
