Seedstockers Seeds: 48 Value Strains From Barcelona

Seedstockers got going in 2017, with an office in Cornellà del Llobregat just outside Barcelona and a second base up in Alkmaar in the Netherlands. That Dutch link is the interesting part, because there are Dutch Passion people behind the breeding work, and it shows in how uniform the plants come out. For a shelf built around value, you get far less seed-to-seed lottery than the price tag suggests.

Who Is Seedstockers? Barcelona Genetics With Dutch Breeding Behind It

The range splits three ways: feminized photoperiods, a fat autoflower lineup, and a smaller run of regular seeds for anyone making their own crosses. Bulk classics like BCN Critical XXL sit next to newer names such as Mack and Crack and Blue Moby, and there are collabs too, with BSF Seeds on the breeding side and with Argentinian rapper Homer el Mero Mero on Rucu Cucu OG. Awards back it up: Triton Biscotto Lime took second in Best Sativa at Amsterdam's Clouds in the City Cup and third for Best Indoor Strain at La Copa de las Flores in Colombia. We get asked whether cheap seeds means old seeds. Ours move fast and sit sealed, cool and dark until they ship, and growers who start with one Seedstockers pack usually come back for the autos.

What We'd Grab First From the Seed Stockers Shelf

Five picks that cover most grow rooms, ranked by how often we'd actually plant them.

• 1. Rucu Cucu OG (Tangie x OG Kush), 8 weeks of flowering, THC up to around 30%. Sweet citrus with a gassy, woody backbone. Watch out for the smell, it's loud from mid-flower, so run a carbon filter if your neighbours are nosy.
• 2. Black Rainbow Auto, eleven weeks from seed to harvest, stays low, and the buds come out frosty and purple-tinted. Grape juice, spice, earth and a little fuel on the palate.
• 3. Santa Marta Haze (Amnesia Haze x Colombian Jungle Haze), 10 weeks flowering, fruity and spicy, soaring head buzz. Outdoors with good light she'll hit 3-4 metres, so train her or give her the space.
• 4. Triton Biscotto Lime (Oreoz Mintz x Lemon Tree), 18-22% THC, 8 weeks, bushy and up to 150cm. Creamy, rich terps and a short finish that suits a short summer.
• 5. Black Rainbow, the photoperiod original, 8-9 weeks, indica-dominant, lemon and grapefruit with spice and earth underneath.

Just off that top five: BCN Critical XXL is the one growers ask about when Indoor yield in g is the deciding number on the spec sheet, while Blue Moby and Mack and Crack give the photoperiod side something less familiar than the usual suspects. On the auto shelf, Mandarin Panties Auto is the citrus-forward alternative to Black Rainbow Auto if you want two very different smells finishing in the same tent. Check each product page for the figures before you commit, since we list what the breeder states rather than guessing.

Photoperiod vs autoflowering cycle length

The autos are the easy entry point here, because you set one light schedule and let the plant run its clock: Black Rainbow Auto stays discreet at eleven weeks from seed to harvest, while Rucu Cucu OG Auto stretches tall for an autoflower and needs 10-11 weeks. Photoperiods give you more control over total time, since you decide how long to veg before flipping, then count the flowering window, 8 weeks for Rucu Cucu OG and Triton Biscotto Lime, 8-9 for Black Rainbow, 10 for Santa Marta Haze. They also reward a bit of ScrOG or LST, especially the Haze end of the shelf.

Every pack ships fast in plain, discreet packaging, and if 48 strains still isn't enough choice, the rest of our cannabis seed range covers other breeders and strain types. Room for one plant only this run? Take Black Rainbow Auto now and keep Santa Marta Haze on the shelf for next summer outdoors.
