About Advanced Seeds

Advanced Seeds is a Spanish seed bank from Murcia, which grew out of a local cultivation shop. Sources differ on the exact founding year, but the company has been producing seeds for well over fifteen years and is known for an organic, low-intervention approach to growing its parent plants.

Its range leans on heavy-yielding, indica-leaning strains. Critical Mass (Afghani x Skunk #1) is its best-known feminized strain, and the Mass family extends into autoflowers such as Auto Critical Mass and Biodiesel Mass (Auto Diesel x Auto Critical).

Prices are dated observations. Each strain page keeps the breeder and seed type together, so a reused strain name from another breeder never mixes in. Prices older than 7 days are labelled with the date they were last checked. Confirm the retailer’s checkout total before buying. Latest catalogue observation: 2026-10-15.
