Underworld was created by crossing 711 with Runtz de Frutas. 711 is a rare cross of J-207 (Lime Kush x W91 x GMO Fuel F3) and Long Valley Royal Kush F11.

Underworld has an indoor flowering time of 56 days after which growers will harvest yields that are said to range from medium to above average depending on the conditions and the grower. The terps. produce an earthy scent and flavor with some notes of citrus. The smoke is deep and smooth and will keep consumers coming back for more.
