"Black Skull Seeds" seed bank

A respected cannabis seed producer and one of the industry’s leading innovators, Black Skull Seeds is owned and operated by a small team of growers from the UK. Now headquartered in Spain, Black Skull is committed to maximizing value for money with every purchase, enabling new and experienced growers alike to cultivate incredible crops with the bare minimum of costs.

For over a decade, these breeders have focused on refining classic Amsterdam genetics such as Jack Herer, Power Plant and Big Bud into super fast finishing feminized hybrids, and developing a line of high-yielding and vigorous autoflowering strains - each in their own right a delight for those growing indoors or with limited summer-time to play with.

Black Skull Seeds started life as the dream of two UK-based growers who fled the draconian cannabis laws of Britain in the early 2000's to find refuge in sunny, canna-friendly Catalonia in Spain.

The pair had been growing ganja for personal use since their teenage years, honing their skills and collecting seeds from trips to Amsterdam, and named their seed bank after an especially filthy and smoke-stained glass bong in the shape of a skull that the duo shared for years in the UK (before the infamous bong met the same shattering end of so much stoner glassware).


Tired of the restrictions in England, these British breeders knew they could thrive in more hospitable climates, but have never forgotten what it is like to grow ganja in the conditions they came from, and this has arguably affected their breeding projects profoundly over the years, helping them focus on creating seeds and strains capable of explosive growth and exceptional yields in even the more sun-starved locations around the world.

Black Skull Philosophy

These breeders have always had the goal of producing epic pot seeds whose plants boast the swiftest of flowering times - a philosophy entirely influenced by their time growing outdoors in the UK, where fast-finishing strains are essential outside.

The Black Skull breeders recognize the value of the autoflowering and feminized strains and how they both serve the seed bank's goals, and have spent many tireless years creating their lines of both, breeding (in their opinion) some of the best weed in the world.


Maximum Bang For Your Buck

The business model at Black Skull is relatively simple, though ambitious to say the least. Famed for engineering a series of exceptionally high-performing autos, these breeders make it easy and affordable to grow quality cannabis in epic quantities. Though suitable for warmer Mediterranean climates, the vast majority of Black Skull’s strains are better suited to controlled indoor environments.

And thanks to the space and sunshine they enjoy in their Spanish home, these breeders have managed to keep production costs way down. When this is combined with their decision not to go wild with affluent spending on advertising, it enables this seed bank to maintain super low prices for all their strains.

Productivity and potency lie at the heart of everything Black Skull, enabling growers at all levels to squeeze multiple cultivation cycles into a single season. More importantly, anyone dealing with restricted space at home (or elsewhere) will find their compact and fast-flowering strains ideal for making the most of every available inch.
