Who Medical Seeds Are & Which of Their 16 Strains to Sow

Say you want six seeds in soil this month, all from one breeder, so your feed and light schedule stays simple. That order is exactly what Collection 2 is for: two 1024, 2046, and Jack La Mota seeds in a single pack, each one over 20% THC. The catch is that none of the three are easy plants, and outdoors they can stretch to a full 3 metres if you give them the room. If that sounds like more plant than you want, browse the wider cannabis seeds range first and come back for these when you've got a tent to spare.

A Barcelona Breeder, Not a Product Category

Medical Seeds S.L. has been breeding in Barcelona since 2005 and has pulled in well over a hundred awards along the way, including cup placings at Spannabis on their home turf and at the Highlife Cup up in the Netherlands. So when you type "medical seeds" into Google, the head result is a brand name. Their newer work shows the pedigree: Mendocino x Purple Kush was released in early 2014 and took three awards that same year, including 2nd place in the concentrate category at Canafac-Acmefuer 2014 and 5th in the indoor category at the Copa THC Valencia 2014.

What People Actually Mean by Medical Cannabis Seeds

Usually one of two things. Either they want CBD in the mix rather than THC alone, or they want a specific cannabinoid balance and terpene set they already know they get on with. Y Griega CBD is the CBD-rich line here; standard Y Griega has been tested at 27% THC and sits at the opposite end of that scale. Myrcene is the terpene that keeps turning up across this catalogue, the earthy, faintly fruity note sitting under most of the indica-dominant phenos. We don't make health claims about any of these seeds, and no honest seed listing should. What we can tell you is the ratio, the terpene direction, and how the plant behaves in a tent.

Sixteen Strains, Four Phenotypes, Plenty of Resin

Mendocino x Purple Kush comes in four phenotypes. The green ones smell heavy and earthy like Purple Kush, the purple ones lean sweet like Mendocino Purple, and you don't know which you've got until she colours up. BCN Sour Diesel is the one that surprises people, sour fuel on the nose and tropical fruit on the exhale, and it holds its own next to Royal Queen Seeds Sour Diesel. No Name tastes like Cheese with a liquorice edge and finishes in 55-60 days, so eight to nine weeks of flowering, and she prefers soil, which is how she picked up her bio prizes. Prozack is the hash grower's pick, short, bushy, dripping resin, though she needs a long veg period before she gets there. Y Griega is the sativa-dominant outlier of the shelf, another week or two in flower and a lot more height outdoors, while the indica-dominant plants like Prozack tend to stay nearer 1.5 metres.

What We'd Sow First, and How It Ships

All 16 strains are feminized and in stock, packed discreetly and sent out fast. There are no autoflowering seeds in this catalogue, so if you want a quick summer autoflower you'll be looking elsewhere in our range, and everything here runs on a photoperiod schedule of roughly eight to eleven weeks in bloom. One tent, one run, and you want a decent harvest without babysitting a sativa in a ScrOG? Take BCN Sour Diesel over Y Griega. Growing outdoors with real space and an October harvest in mind? Mendocino x Purple Kush or Devil Fruit. And if you can't choose, Collection 4 puts No Name, Malakoff, and Devil Fruit in one box, two seeds each.

Frequently asked questions

Who is Medical Seeds?

Medical Seeds S.L. is a Spanish breeder based in Barcelona, working since 2005 and holding more than a hundred cup placings. Their focus has been cannabinoid balance and strong Kush and Haze crosses. We stock 16 of their feminized strains, from 1024 to White Widow.

Are medical cannabis seeds high in CBD?

Not always. Some lines are CBD-rich, like Y Griega CBD, while others in the same catalogue are THC-heavy, with standard Y Griega tested at 27%. Check the cannabinoid figures on each product page rather than going by the breeder name alone.

Which Medical Seeds strain hits hardest?

Y Griega, on the numbers, at a tested 27% THC with an energetic buzz that settles into relaxed alertness. She takes off fast though, so grow her in a ScrOG or she'll outgrow your tent. If you want something strong but easier to manage, BCN Sour Diesel is the safer pick.

Do you sell Jack La Mota seeds?

Yes. Jack La Mota comes as a single strain and also inside Collection 2, alongside 1024 and 2046, two seeds of each. All three of those push past 20% THC and can reach 300cm, so plan your headroom before you sow.
