About Blueberry
Genetics & strain profile
Blueberry is one of the most famous strains in cannabis, first developed in the 1970s by combining Afghani, Thai and Purple Thai genetics and later a Cannabis Cup winner. Our feminized Blueberry is bred by Quebec Cannabis Seeds from that original line: a 75% indica hybrid with 24% THC and plenty of resin — “CAKED in trichs”, as one reviewer put it. It suits novice growers as well as experienced ones, and with 19 reviews averaging 4.8 out of 5 it is one of our best sellers. One point of honest debate in the reviews: a grower found his phenotype tall and sativa-like, which is possible with the Thai heritage, while most describe a thick, indica-dominant plant. Expect some variation between seeds.
How Blueberry grows
Blueberry flowers in 50 to 60 days, which is fast for a photoperiod strain, and gives up to 500 g/m² indoors with proper care; it does well in soil, in hydro and even started straight at 12/12 in a 5-gallon fabric pot, as one reviewer did. A grower in DWC harvested 100 g from a single plant with “minimal issues” and called it very easy. Outdoors the plants reach a moderate height and are harvested early to mid-October, with up to 300 g per plant depending on conditions. A public grow diary recorded 101 g wet at 92 days outdoors and praised how well the plant held up through gale-force winds and three-day rainstorms. The classic Blueberry tip still applies: cooler nights late in flower bring out the purple and the smell.
Taste, aroma and effect
The flavour is sweet berry with earthy and herbal notes — reviewers describe “a strong mix of blueberries and spice and a small amount of skunk” and an “impressive stank” at week 7. The effect starts with mental clarity and euphoria, then spreads through the body, relaxing and soothing, which makes it a good evening strain that does not knock you out immediately. If you want this flavour with a faster finish, see Blueberry Fast Version; for a heavier indica from the same parent, Blue God.

Beautiful Blueberry pheno. very photogenic. Smells amazing. The aroma is strong with a mix of blueberries and spice, and a small amount of skunk.
Started her off in 12-12 lighting in a 5 gallon fabric pot and self watering base. I did some manifolding once branching started around week 4 or 5 to keep her short, and set her up as a six-shooter with a big opening in the middle. In the stretch phase she exploded with secondary and tertiary branching that is naturally spaced out well, with a fairly even canopy at just over 2x2x2ft in dimensions. The main branches are thick and sturdy with nicely spaced out nodes for easy trimming later. All around a great mix of indica and sativa structure. Vigorous and healthy. Eats like a pig, drinks like one too.
I'm only just going into mid-flower so I can't comment further, but I wanted to pay compliments to QCS for the quality genetics.

I waited until harvest to review. Seeds arrived quickly. Germinated one seed via paper towel method, planted in vgrow dwc. 100 gram harvest. Beautiful purple and green flowers that are CAKED in trichs. Very easy strain to grow, minimal issues. Off of my one plant I took 12 clones below the canopy before flip and all rooted. I took another 12 clones off of those clones. I now have 24 clones for the great outdoors and 100 grams of top shelf all off of one seed. I cant wait for my next purchase in the fall.

Seems thick Indica dominant at week 7 resinous and flavourful under 1000 w hps with general hydro nutes. Impressive stank

Mine is tall like a sativa. The 75% Indica is wrong. You can't breed two different sativa's with a indica and say that it is indica dominant. To me the way it is growing. It is 75% sativa.
All Thai strains are sativa's. You used two to breed with one indica. So far I like the way it grows.
