Description
Mosca Seeds built Bluemosa S1 by taking their Blumosa, a cross of Blue Cookies and Mimosa, and selfing it to stabilise and concentrate the best traits of both parents. The result is a feminised photoperiod variety with very high THC above 25% and a clean, fruity character, think fresh citrus lifted by a deeper berry sweetness. Effects sit at the potent, euphoric end of the spectrum, carrying the social uplift of Mimosa alongside the more grounding qualities of Blue Cookies.
In the grow room, Bluemosa S1 is a genuinely rewarding cultivar for growers who can give it the attention it deserves. Flowering wraps up in 7 to 9 weeks, a window that fits comfortably into most indoor schedules, and indoor yields run 450-600 g/m2, enough to fill a tent meaningfully from a modest plant count. Outdoor plants can push 450-750 g per plant under a generous sun. Being feminised, every seed goes toward a productive flowering plant. For cultivators looking to dial in a high-performing fruity variety with proven genetics, Bluemosa S1 is a serious candidate.

about this product
Bluemosa S1 from Mosca Seeds packs citrus-berry flavour and 25%+ THC into a high-yielding feminised photoperiod ready for growers looking to elevate their next run.
The effects lean potent and euphoric, drawing on Mimosa's sociable, uplifting energy balanced by the more grounding influence of Blue Cookies. With THC sitting above 25%, this is a strain that rewards respect — best suited to those already comfortable with high-potency varieties.
Bluemosa S1 carries a bright, fruity profile built around fresh citrus top notes and a deeper, lingering berry sweetness that reflects both sides of its Blue Cookies and Mimosa parentage. The aroma is clean rather than heavy, making it a pleasure to work with in the grow room as well as after harvest.
Indoors, Bluemosa S1 is capable of producing 450–600g per square metre, while outdoor or unconstrained plants can reach 450–750g each. Flowering wraps up in 7 to 9 weeks, so you're looking at a relatively efficient turnaround for the output on offer.
Mosca Seeds rates Bluemosa S1 as easy to moderate, which puts it in reach of intermediate growers who understand the basics of light cycle management and canopy control. It isn't the most demanding photoperiod variety out there, but giving it consistent care is what unlocks those high-end yields.
