"Mold resistant" means mold tolerant: less prone to mold and slower to be affected. No strain is 100% mold resistant. How we set these numbers →

About Blueberry

Genetics & strain profile

Blueberry is derived from the original Blueberry strain, first developed in the 1970s by combining Afghani, Thai and Purple Thai genetics. It is a 75% indica hybrid with 24% THC and plenty of resin, and it suits novice growers as well as experienced ones.

How Blueberry grows

It flowers in 50 to 60 days, which is relatively fast, with up to 500 g/m² indoors with proper care.

Outdoors the plants reach a moderate height. Aim to harvest in early to mid-October, with up to 300 g per plant depending on the growing conditions.

Taste and effect

Sweet berry, with earthy and herbal notes. The high starts with mental clarity and euphoria, then spreads through the body: relaxing and soothing.

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.

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.
