BSB Genetics Cannabis Seeds: 18 Feminized Strains

Let's kill one myth first: a shelf full of famous names doesn't mean these are other people's seeds with a new label slapped on the pack. BSB Genetics is a small, award-winning UK-based brand with over 18 years of experience, and breeder-direct sourcing is how they work, collaborating closely with other breeders to bring in genetics from around the world. Their Gorilla #4 came from an original Gorilla #4 cut, with Chem's Sister, Sour Dubb and Chocolate Diesel behind it, which is why it sits happily beside every other reading of that legend in our Gorilla Glue category.

Eighteen Strains, All Feminised, One Small Team

Eighteen strains on this shelf and every one of them is feminised, so you're not spending week five hunting for males. Twelve run on a light cycle and six are autos, which makes the photoperiod-versus-auto call the first real decision here. The collaboration habit explains the line-up: Cali Cookies is BSB's take on Girl Scout Cookies (Durban Poison x OG Kush), and Bruce Banner pulls OG Kush together with Strawberry Diesel. The Bruce Banner strain itself took 1st place in the Most Potent Strain category at the 2013 High Times Cannabis Cup. Want the wider picture? The rest of our cannabis seeds sit next door, but BSB fits a lot of well-known genetics into a short catalogue.

The Photoperiod Strains: Nine Weeks, Give or Take

Blackberry Nuggets is the loud one. Blackberry Kush x Blue Moonrock, up to 33% THC, 8-9 weeks of flowering and up to 500g/m² under a 600W lamp, with buds so packed with resin they smell of sweet berry and candy before you've even cut them. Strawberry Banana runs 9 weeks for up to 550g/m², banana and berry with a peppery edge, and it's the forgiving one here. Cali Dream (Blueberry x Super Silver Haze, 19% THC) gives the biggest indoor figure at up to 600g/m² in 9-10 weeks, though it leans sativa, so anyone set on indica-dominant genetics and a tidier canopy will want one of the others. Cali Cookies reaches up to 28% in 8.5-9 weeks with chocolate and mint on the palate, and Gorilla #4 averages 26% across 7-9 weeks. Watch out for Gorilla #4's weight: those buds get sticky and heavy, so get the branches supported early. Bruce Banner stays at 120-150cm indoors over 9-10 weeks. Most of this side sits in 8-10 week flowering windows, and The Runtz, Mimosa, Amnesia Haze, Cali Cherry Pie, 24K Tangie and Lemon Haze fill out the rest.

The Autoflowering Seeds: They Run on Their Own Clock

Mandarine Dream XL Auto and Auto Diablo XL are the autoflowering XL lines, joined by Auto Strawberry Milkshake, Auto Anthrax, Auto Critical+ and Auto Sweet Tooth. They start flowering when they're ready rather than when you flip the lights, which is handy on a windowsill and less handy if you like heavy training. Across the shelf that means finishing times from roughly 5 to 10 weeks, depending on the strain you pick. The trade-off shows in the numbers: Auto Sweet Tooth is documented at up to 16% THC, well under the 33% on Blackberry Nuggets. Choose an auto for the timeline, not for the biggest figure.

Where We'd Start on This Shelf

First BSB seed? Strawberry Banana. It's easy going, the canopy stays dense with purple showing through the bright green, and 9 weeks is a fair wait. Chasing the highest documented THC on this shelf instead? That's Blackberry Nuggets at up to 33%, and it's the one we'd keep off a first grow. After the full Cali line? Cali Dream, Cali Cookies and Cali Cherry Pie sit together above. If you'd rather skip light cycles and still want that Banner citrus and diesel character, Bruce Banner Auto by FastBuds sits on a different shelf in our feminised seed range. New to feminised seeds altogether? Follow our germination guidance and keep spare beans cool, dark and dry. Orders go out in discreet packaging with fast UK shipping, so the seeds arrive ready to sow instead of ageing in a warehouse for a season.
