BSB Genetics Seeds: 18 Feminized Strains From the UK Breeder

Picture a 600W lamp, one tent, and about nine weeks of patience. That's the window most of this shelf fits inside, which is why we send growers here when they want a legendary name without signing up for a 12 week sativa marathon. Everything BSB makes is feminized, so if you're after regular seeds for breeding work you'll want the wider cannabis seeds catalogue instead.

A Small UK Breeder With a Big Contacts Book

BSB Genetics is a small, award-winning UK-based brand with over 18 years of experience in the field. They work closely with other breeders rather than in a sealed room, and that's how genetics from all over the world end up under one label. It also explains why so many famous names show up here as BSB versions: Gorilla #4 from an original cut, plus Amnesia Haze, Mimosa, The Runtz, 24K Tangie and Lemon Haze.

Blackberry Nuggets, the One People Search By Name

Blackberry Kush crossed with Blue Moonrock gives you an 80% indica that grows hard without much babysitting. Flowering runs 8-9 weeks and under a 600W lamp she can hand over up to 500g/m² of densely packed, resin-caked buds. Open the jar and it's sweet berry and candy, closer to a sweet shop than a skunk. At up to 33% THC it's the highest figure documented anywhere on this shelf, with Auto Sweet Tooth at up to 16% sitting at the other end of the same range.

The Cali Picks and the Legends Beside Them

Cali Cookies is BSB's take on Girl Scout Cookies, a Durban Poison x OG Kush that frosts over a few weeks into flowering, up to 28% THC, 8.5-9 weeks and up to 500g/m², with chocolate and mint running through the flavour. Cali Dream leans the other way: Blueberry x Super Silver Haze, 19% THC, citrus and berry up front with an earthy finish, 9-10 weeks and up to 600g/m². Grow difficulty on that one is moderate, so it pays off more for someone who has already handled a stretchy canopy. Gorilla #4 has Chem's Sister, Sour Dubb and Chocolate Diesel behind it, 26% THC on average, earthy with a sour edge, and buds so heavy that you want stakes or a net in place before they thicken up. Bruce Banner joins OG Kush with Strawberry Diesel, stays at 120-150cm indoors, finishes in 9-10 weeks and can reach up to 600g/m² under a 600W light; the Bruce Banner strain took 1st place in the Most Potent Strain category at the 2013 High Times Cannabis Cup. Curious how BSB's reading of the Gorilla compares to other breeders' cuts? Our Gorilla Glue category lines them all up.

Autos for When Space and Time Are Tight

The autoflowering side of the shelf covers Mandarine Dream XL Auto, Auto Diablo XL, Auto Strawberry Milkshake, Auto Anthrax, Auto Critical+ and Auto Sweet Tooth. They run on their own clock, so there's no light schedule to manage and no fuss about flipping. The trade is real: none of them match the photoperiod numbers above, and Auto Sweet Tooth tops out at 16% THC where Blackberry Nuggets reaches 33%. Strawberry Banana is the middle ground if you can commit to a photoperiod, a 70% indica that goes bright green and purple, finishes in 9 weeks, yields up to 550g/m² and tastes of banana and berry with a peppery kick.
