Last reviewed: October 2026. This page summarises Spanish law for information only and is not legal advice. Spain’s position rests on court doctrine as much as statute, and regional practice varies.
The short answer
| Buying cannabis seeds | Legal; Spain is home to many of Europe’s seed breeders |
|---|---|
| Possessing seeds | Legal |
| Germinating and growing | Not a crime for personal use in a private space out of public view; no plant number is set in law |
| Plants visible from the street | Administrative fine of €601 to €30,000 under the Citizen Security Law, plus seizure |
| Use or possession in public | Same administrative fine range; €601 is routinely applied |
| Sale, supply or large-scale cultivation | Criminal offence (Penal Code art. 368), 1–3 years and upward |
Private is the whole story
Spain has never criminalised private cannabis use. The constitutional protection of the private sphere, as interpreted by the Constitutional Court and the Audiencia Nacional over several decades, keeps consumption and cultivation for one’s own use inside the home outside criminal law. Everything that crosses the threshold into public space, or into supply to others, is penalised: public use and possession as administrative infractions under Organic Law 4/2015 (the “Ley Mordaza”), sale and trafficking as crimes under the Penal Code.
Seeds specifically
Seeds are freely sold and bought. The country’s breeding scene — 00 Seeds, Sweet Seeds, Pyramid Seeds, Ripper, Eva, Silent Seeds and others — operates openly, and Spanish-bred autoflowers and feminised lines are stocked across Europe. There is no restriction on quantity or on ordering from other EU countries.
Cultivation: the rules the courts apply
No statute fixes a number of plants. What the courts look at is whether the grow is consistent with personal consumption and whether it is private. In practice that means:
- Out of public view. Plants visible from a street, a neighbour’s window or a public path trigger the administrative fine, and the police seize them. A roof terrace is private only if nobody can see onto it.
- A quantity a person could plausibly use. Two or three plants is the figure often cited by lawyers; a dozen plants, scales, packaging or cash shift the case toward trafficking, which is where the Penal Code applies.
- No supply. Giving cannabis to anyone else is supply. Cannabis social clubs exist in a grey area built on a “shared consumption” doctrine; the Supreme Court has drawn that doctrine narrowly and prosecuted clubs that behaved like shops.
Penalties
For a small private grow kept out of sight, the realistic exposure is nil. For plants seen from outside, the fine under Organic Law 4/2015 runs from €601 to €30,000, with most cases at the bottom of the range, and the plants are confiscated. Cultivation with evidence of distribution is prosecuted under article 368 of the Penal Code, with sentences starting at one to three years for small quantities.
What this means when you choose seeds
Spain is the easiest country in Europe to grow in: a long season, strong sun and a legal position that leaves private growers alone. The constraint is visibility, not climate. Indoor growers have free choice. Outdoor growers on balconies and terraces favour compact autoflowers and medium-height indicas that stay below a railing or screen, and run two cycles a year. In the south and east, long-flowering sativas that would never finish in the north — 11- to 13-week Hazes and landrace lines — mature comfortably in October. See the seed buying guide and the strain pages; each strain’s planning section notes which climates it suits.
Frequently asked questions
How many plants can I grow in Spain?
The law sets no number. Courts look at whether the quantity is consistent with personal use; a few plants, out of public view, is not a crime.
What is the fine for plants on my balcony?
If they can be seen from a public place, €601 to €30,000 under the Citizen Security Law, plus seizure. Screened from view, there is no infraction.
Can I buy seeds in Spain and take them home to another EU country?
Buying is legal in Spain. Whether you may possess or grow them at home depends on your own country’s law — see our pages for Germany, the Netherlands and France.
