Advanced Seeds started as a small grow shop in Murcia and turned into one of Spain's most practical seed banks: 36 strains here, every one feminized, priced for growers who plan to fill a tent rather than a display case.
The breeders built their catalogue on Skunk, Kush and Diesel genetics, then crossed those workhorses with American cultivars to modernise the flavours. Their original Critical Mass descends from Skunk and Afghan lines, which is exactly why it forgives mistakes. Production runs on organic methods with natural fertilisers, and feminized seeds are made without genetic engineering, in isolated chambers to keep each strain true.
Every seed in the range is feminized, so there are no males to cull. Afghan Skunk is the easy old-school pick at 17% THC in 8-9 weeks.
Around fifteen autos cover the impatient end, from Auto Amnesia XXL (14% THC, big yields, 11-12 weeks from seed) to the punchy Auto Zkittlez at 20%.
Flowering time runs from 6 weeks on the Fast versions to 12 weeks on the slowest autos, and the catalogue covers both indica and sativa hybrids with THC content stated on every card. Slurricane and Zerealz Milk both hit 28%, the ceiling of this catalogue.
| Strain | Type | THC | Flowering |
|---|---|---|---|
| Critical Mass Fast | Fast | 22% | 6-7 weeks |
| Forbidden Fruit Cake | Feminized | 26% | 6-7 weeks |
| Auto Bruce Banner XXL | Autoflower | 24% | 10-11 weeks from seed |
| Fire DOG | Feminized | 25% | 9-10 weeks |
Critical Mass Fast is the standout: 40-45 days of flowering and up to 650 g/m² indoors, the biggest yield in the range.
We stock all 36 strains fresh and ship them discreetly, alongside the rest of our cannabis seeds. One honest caveat: with no regular seeds in the catalogue, breeders hunting males will need to look elsewhere.
Spain. The seed bank grew out of a grow shop in Murcia and breeds mainly from Skunk, Kush and Diesel lines crossed with American cultivars.
No. All 36 strains we stock are feminized, so every seed should produce a female plant. If you need males for breeding, you will have to look at another seed bank.
Critical Mass Fast, at up to 650 g/m² indoors, and it does that with a 40-45 day flowering time. Several others reach 600 g/m², including Auto Amnesia XXL and Bruce Banner.
Fast versions are still photoperiod plants, so you control when they flower, but the flowering phase is shortened to roughly 6-8 weeks. Autoflowers switch by themselves and finish the whole cycle in 8-12 weeks from seed.
