Seb's take
Blueberry crossed with a ruderalis line, and the fruit carries through plainly — sweet blueberry over earth on the nose. The high lifts rather than sinks: uplifting, happy, euphoric, at a gentle 14% THC. She grows tall and single-stemmed for an indica, so the Sea of Green suits her better than a spreading canopy.
Where it comes from
Royal Queen Seeds paired the legendary Blueberry with a ruderalis cutting to make this autoflower — the Blueberry, one of the most celebrated fruit lines in the catalogue, lending its flavour and colour, the ruderalis the self-timing habit. She comes out overwhelmingly indica-dominant yet, the record notes, grows with a sativa's structure: a long, single apical stalk rather than a spreading bush. A fruit classic turned auto, with a growth habit that shapes how you ought to run her.
Nose & flavour
Sweet blueberry leads the nose, true to the parent, over an earthy base that keeps it grounded — a soft, ripe, fruit-forward profile with none of the sharpness of citrus or fuel. It is the Blueberry signature carried faithfully into an autoflower: sweet and moreish, the sort that flatters a grow room. Distinct and easy to place, which is much of Blueberry's enduring appeal.
The high
The effect lifts rather than sinks: uplifting, happy and euphoric, a brighter experience than the heavy indica frame might lead you to expect. At a gentle 14% THC with medium CBD it stays light and sociable — a cheerful, functional sort of high rather than a sedating one. Good daytime company, easy-going and undemanding, in keeping with the plant itself.
Growing it
Because she grows tall and single-stemmed rather than branching, the Sea of Green suits her ideally — packed close, each plant a long central cola. Chop that apical dominance and she throws side branches instead, ready for low-stress training. She is easy on nutrients, the record noting she handles almost anything, and does well indoors or out. Flowering is quick at 49 to 56 days, height a compact 60 to 75cm, yield a solid 425–475 g/m² at 14% THC. A forgiving, adaptable auto with a clear preferred method.
