Dr Underground is a niche seed bank founded in 2008 in the Canary Islands. A small team of enthusiasts set out to develop their own premium, feminized strains that combine intense flavor, high yields, and ease of cultivation. Their location in the subtropical climate of Las Palmas allowed them to experiment with a wide spectrum of sativas and indicas, and the results quickly gained recognition among collectors worldwide.
Characteristics and philosophy
Dr Underground is known for a distinctive approach to parent selection: each cross is created with a specific trait in mind—whether flowering speed, potency, or uncommon terpene profiles. All seeds are feminized, and the producers run regular tests to maintain phenotype stability. The bank offers both sativa-dominant lines such as King Kong and Auto King Kong, as well as heavy indicas like Painkiller and Black Jesus OG.
Overview of popular strains
Melon Gum – a blend of Lavender and Bubble Gum delivering exotic fruit and sweet gummies in one; yields reach 400–500 g/m2 in 55–60 days.
King Kong – a hybrid of Chronic, Ed Rosenthal Super Bud, and Skunk; huge, resinous colas and a euphoric, motivating effect.
Painkiller – indica-dominant; stands out for high CBD with moderate THC (5–15%), making it suitable for therapeutic use.
Black Jesus OG – a cross of Black Domina, Jack Herer, and San Fernando Valley OG; combines a heavy, earthy note with citrus freshness.
Performance and cultivation
Dr Underground seeds are praised for high productivity. Indoor versions can deliver 350–450 g/m2, and with intense lighting and hydro even 550–750 g/m2. Plants stay at a moderate height (80–140 cm) and respond well to LST, ScrOG, and defoliation. The company emphasizes discreet packaging and includes a detailed description for each phenotype.
Growing tips
Climate – most strains prefer moderate conditions with plenty of light. Outdoors in a Mediterranean climate, plants mature from late September to mid-October.
Training – LST and topping help control structure; plants can branch heavily, so using a net is recommended.
Feeding – the genetics are hungry; use high-nitrogen nutrients in veg and phosphorus/potassium-rich feeds in bloom, but watch closely for signs of overfeeding.
