Pheno Finder Seeds: Feminised Cannabis Seeds

The name gets misread as a gimmick, but pheno finding is the actual job here. Pheno Finder Seeds is a team of growers and breeders from Holland, Spain and the USA, and their whole thing is hunting down the standout plant in a population and then bottling it as seed. We stock 13 of their feminised strains, from the Notorious OG they kept as a secret clone for over two years to newer work like Rainbow Cake and MAC 11, plus one autoflower in Auto Fruity Kuntz.

What Pheno Finder Actually Hunt For, and Which Strain to Grow

Here's the misconception worth clearing up: a phenotype isn't a strain name. Two seeds from the same pack share a genotype, the genetic code, but the plant you actually end up with is the phenotype, and that's the genotype filtered through your grow room. Your light, your temperatures, your feeding schedule. Grow ten Wedding Cake seeds and you'll get ten slightly different plants, some taller, some frostier, one that smells noticeably better than the rest. Pheno hunting means growing out that whole population, keeping the standout, and binning the rest. It's slow, it eats space, and most home growers never bother. That's the work Pheno Finder Seeds has already done for you.

The S1 Badge, and Why It Matters on Your Shelf

When you see S1 on Simple Wedding Cake S1 or Purple Strawberry Bliss S1, that means self-pollinated: one selected mother crossed with herself, so the offspring stay close to that single kept plant instead of scattering. Double Slurry is the same idea applied to the Slurricane #7 cut, an S1 built to lock in the sweet, creamy fruit and the resin coverage. The trade-off is honest enough. S1 lines can be less genetically varied than a proper F1 cross, so if you enjoy the lottery of hunting your own keeper, a wide open hybrid pack from our main cannabis seeds range gives you more to sift through. If you want the plant the breeder already picked, S1 is the shortcut.

Cups, Trophies and What the Wins Actually Tell You

Pheno Finder Seeds has a genuine trophy shelf. Lemon Bubble is the big one: 1st Place Seed at Finder Cup 2015, 1st Place THC at Valencia Copa 2015, 3rd at the High Times Cannabis Cup 2014, 3rd at Expo Grow Run 2014, and 2nd at Secret Cup Canaria 2014. Notorious OG took 2nd at Copa Cannaval 2014 and 3rd at the Canary Islands Cup 2015. Fromage Blue took 2nd at the Canary Island Cup 2015, and Purple Strawberry Bliss S1 came 3rd at the IC 420 Sativa Cup 2014 in Amsterdam. Simple Wedding Cake S1 descends from a High Times Cannabis Cup winning cut. A cup win tells you the breeder found something worth showing, not that the plant grows itself. Rainbow Cake, at over 25% THC, still stretches hard and will chase the ceiling of a small tent if you let it.

Picking Your First Pack From the Thirteen

Start with Notorious OG if you want the easy one. It's indica-dominant, bushy, low-maintenance indoors, outdoors or in a greenhouse, and it finishes in nine weeks with dense buds carrying that deep sour kush smell that clings to your fingers after a trim. Lemon Bubble is the sativa-leaning pick, 60% sativa, 9-10 weeks, and it throws enough resin to be worth running for hash. Do Z Dos is the fastest at 8-9 weeks, with lime green and purple flowers if you can drop night temperatures at the end. MAC 11 is the one to leave until later, because it needs closer attention to grow room conditions than the rest. Auto Fruity Kuntz is the only autoflower on this shelf, so if you specifically want autos, our wider seed range covers that far better. Grandaddy Confidential, LA Fire, Sour Walker and Fromage Blue round out the rest for anyone chasing colour and old-school Skunk and pine notes.

Frequently asked questions

What does pheno actually mean when talking about weed?

Pheno is short for phenotype, the plant you actually get when a set of genetics meets a particular grow room. Same seed pack, same genotype, but light, temperature and feeding push each plant slightly differently, so one comes out taller or frostier than its sisters. Breeders pick the best of those expressions and work with it.

What is pheno hunting, and do I need to do it myself?

Pheno hunting means germinating a load of seeds from the same cross, growing them all out, and keeping only the standout plant as a mother. It takes space, time and a lot of patience, which is why most home growers skip it. Pheno Finder Seeds does that selection work first, so the seeds you get already come from a chosen plant.

What does the S1 in Simple Wedding Cake S1 mean?

S1 means self-pollinated: one selected female was crossed with herself rather than with a male from another line. The result stays close to that single kept plant, so you get more consistency across the pack. Double Slurry and Purple Strawberry Bliss S1 use the same method.

How many Pheno Finder Seeds strains do you stock?

Thirteen, all feminised. Twelve are photoperiod, including Notorious OG, Lemon Bubble, Rainbow Cake, MAC 11, Double Slurry, Do Z Dos, Simple Wedding Cake S1, Grandaddy Confidential, Purple Strawberry Bliss S1, LA Fire, Fromage Blue and Sour Walker. Auto Fruity Kuntz is the single autoflower.

Which Pheno Finder strain is best if I have never grown before?

Notorious OG. It's vigorous, indica-dominant, doesn't ask for much, and it handles indoor, outdoor and greenhouse setups. Save MAC 11 and Rainbow Cake for your second or third run, since both want closer attention and more headroom.
