Ace Seeds — short for Asociación Cannábica de Estudios — is the Spanish seed bank that built its reputation on preserving original landrace genetics rather than chasing the latest dessert hybrid. While most of the industry was crossing cookies with gelato, Ace was tracking down pure Malawi, Panama, Kali China and Zamal cuts and stabilising them as seed. If you've ever wanted to grow something that tastes like cannabis did before the polyhybrid era, this is the part of the seed wall we point you to.
The catalogue splits roughly three ways: pure landraces and heirlooms (Malawi, Kali China, Golden Tiger, Hokkaido Japan Hemp), modern sativa hybrids built on those lines (Zamaldelica, Purple Haze x Malawi, Haze x Kali China), and the cold-climate / outdoor-friendly work like Erdpurt and Violeta. Most varieties come as regular seeds, with a smaller selection of feminised options for growers who don't want to sex plants.
If it's your first Ace grow and you're working outdoors in northern Europe, start with Erdpurt or Violeta. Both are short-flowering and built for the climate — they'll finish before autumn rot sets in and they don't demand the long season that sativas need. If you're indoors with a short tent and limited patience, these are also the easiest entry point into the catalogue.
Intermediate growers who want a taste of what Ace actually specialises in should look at Zamaldelica or Purple Haze x Malawi. These keep the sativa flavour and high but bring flowering down to a manageable range and add hybrid vigour. Expect tall, stretchy plants and a longer flower than dessert hybrids — flip early under lights, or train heavily.
If you've grown long-flowering sativas before and know what you're doing, the pure lines are where it gets interesting. Golden Tiger, Malawi and Kali China are not beginner plants. They stretch, they flower for 12–16 weeks, and they reward patience with cerebral, classic highs that polyhybrids simply don't reproduce. Run them in a tall tent, give them time, and pheno-hunt from regular seed if you want to find keepers worth cloning. Hokkaido Japan Hemp sits slightly outside the rest of the catalogue — it's a northern hemp line, useful for fibre, seed and breeding projects rather than recreational flower.
Ace specialises in landrace preservation and sativa-dominant genetics. While most breeders work with the same handful of modern cookie and gelato lines, Ace maintains pure Malawi, Kali China, Panama and Zamal genetics, plus hybrids built on those backbones. If you want original-style sativa flavour and effects, this is the catalogue.
The cold-climate lines — Erdpurt and Violeta — are beginner-friendly outdoor varieties for northern Europe. The pure sativas and landraces are not. They flower for 12–16 weeks, stretch significantly, and need a grower who understands long-flower sativa management. Start with a hybrid like Zamaldelica if you want a middle ground.
Most of the Ace catalogue is sold as regular seeds, which is the format breeders and seed-savers want for pheno-hunting and producing your own seed stock. If you only want female plants and don't intend to breed, check the listing for a feminised version of the variety you're after.
Yes, but plan for height. Pure sativas like Malawi and Golden Tiger will stretch hard in flower — flip them at 20–25 cm or train them flat. Erdpurt, Violeta and the shorter hybrids fit standard tents without much fuss. Long-flower sativas also benefit from a slightly extended veg-to-finish timeline, so factor that into your cycle planning.
