Description
Underworld Feminized is the work of Mosca Seeds, built on a compelling genetic foundation: 711, itself a layered cross drawing from J-207 (Lime Kush, W91, and GMO Fuel F3) and Long Valley Royal Kush F11, bred with Runtz de Frutas. The result is an indica-dominant variety with an earthy, grounded aroma that opens into softer fruity notes. The smoke is smooth and full-bodied, with an effect profile that settles in steadily and invites you to slow down.
As a feminised photoperiod strain, Underworld is a reliable choice for growers who want to control their vegetative window before triggering flower. Indoors, she finishes in 7 to 9 weeks and returns average yields in the 350-450 g/m2 range, respectable numbers for a single tent or dedicated grow room. Outdoor plants in suitable conditions can yield 200-450 g per plant, rewarding those who give her space to develop. For cultivators drawn to rare, complex genetics with roots this deep, Underworld is well worth making room for.

about this product
Underworld Feminized from Mosca Seeds combines rare 711 and Runtz de Frutas genetics, delivering earthy depth and potent body relaxation ready for growers who mean business.
This strain sits comfortably in the easy-to-moderate category, making it a solid step up for intermediate growers who have a grow or two under their belt. As a feminised photoperiod, it gives you full control over the vegetative period, so you can dial in plant size before flipping to flower — a real advantage if you want to manage your space thoughtfully.
The aroma is grounded and earthy at its core, with softer fruity notes that open up as the plant matures — a profile inherited from the Runtz de Frutas side of its lineage. The smoke itself is smooth and full-bodied, with that earthy foundation carrying through to the finish rather than fading into the background.
Underworld carries a high THC range of 16–24%, so potency is firmly in serious territory. The effect settles in gradually and leans heavily into relaxation and body weight — this is a couch-lock cultivar by design, best enjoyed when you have nowhere to be.
For a Mosca Seeds release built on the relatively rare 711 line, a 6-pack gives you enough phenotype variation to identify a standout keeper without over-committing. With feminised seeds and a forgiving difficulty level, you're unlikely to lose plants to male selection, meaning most of those six have a strong chance of making it to harvest.
