Dr. Underground Feminized Cannabis Seeds

Eighteen years in, Dr. Underground still works the way it started: a Spanish bank breeding feminized seeds from its own stable, one cross at a time. Here's what that gets you.

Who Is Dr. Underground? A Feminized-Only Seed Bank From Spain

Dr. Underground has been breeding out of Spain since 2008, and everything it releases is feminized. The range at Zamnesia runs to fourteen products: two autoflowers, the rotating Surprise Killer Mix, and eleven photoperiod strains, most of them crosses of the bank's own earlier work. Plenty of growers shorten the name to Underground seeds. New to feminized? Our feminized cannabis seeds page breaks it down, but the short version is that nearly every seed becomes a female, bud-bearing plant.

Signature Strains: The King Kong Family

King Kong (Super Bud x Chronic) is the bank's workhorse, done flowering in 7-8 weeks, and a fair chunk of the catalogue descends from it. Auto King Kong turns the same genetics around in 8-9 weeks from seed to harvest, Kong 47 sharpens it with AK47, and Godzilla Glue crosses it with Gorilla Glue 4 for the resin chasers. One honest catch: most Dr. Underground strains carry no published THC percentage. The catalogue says High or Medium, full stop. If you want lab decimals on every pack, FastBuds is the spec-sheet bank on our shelf; if lineage and grower reports are enough, you'll be fine here.

Melon Gum, Brooklyn Mango and the US-Leaning Drops

Melon Gum (Lavender x Bubblegum) is the flavour flagship, sweet melon over bubblegum in 7-8 weeks, and Auto Melon Gum brings the same taste to auto growers in 10-11 weeks total. Brooklyn Mango layers ripe mango over NYC Diesel fuel. The newer drops lean American: Black Jesus OG and Dark Cookie both build on Tahoe OG, while American Beauty, a Plushberry selection, is the range's yield monster at up to 1000 g per plant outdoors. That number is not abstract: it means branches bowing under their own bud weight and a trim job that eats your whole weekend.

Which Dr. Underground Seeds Should You Pick for Your Grow?

Indoors on a tight schedule, we'd go King Kong or Melon Gum, both wrapped in 7-8 weeks. On an autoflower setup, Auto King Kong is the quicker of the two autos. Chasing outdoor weight, American Beauty; chasing modern US flavour, Dark Cookie or Black Jesus OG. Old-guard picks PainKiller and Crystal M.E.T.H. are still here too, pure 2000s pedigree. Stock turns over fast, like the rest of our cannabis seeds, so packs stay fresh and every order ships discreetly. Our own starting point would be Melon Gum: easy weeks, loud flavour.
