Shops which sell marijuana seeds are misleading customers by telling them they can grow two plants for private use. The Guardia Civil confirms that cultivation of marijuana plants is considered a crime against public health, be it one plant or 500. The Guardia have recently started judicial action against a couple who had just four plants.

Outside of the European Union, Spain is now one of the main areas of marijuana cultivation, and the number of marijuana plantations discovered by the police has soared, especially in the Valencia region.
Dutch mafia groups are believed to be organising and controlling marijuana plantations across Andalucía, Murcia, Cataluña, Aragón, and in particular the Valencia region where Alicante is said by a Civil Guard antidrug source to be ‘a cannabis jungle’!
‘There are plantations in nearly all the municipalities of Alicante province and in many in Valencia, because of their orography and climate’, adding that homemade greenhouses have been set up in flats and villas, and more sophisticated operations had been established in warehouses.
These large operations are controlled by the Dutch mafias and they have sent technicians to ‘teach’ the Spanish. More than 17,000 Dutch live in the Valencia region, 15,000 of them in the province of Alicante. Some recent discoveries include 47 plants in Alcoy, 330 in an Alicante flat, 600 in a villa in Elche, 735 in a house in Oliva, 104 in Torrent, 172 in Granja de Rocamora, and 676 in Valencia.
The plants don’t need earth, as they can be fed by an irriagation, system fortified with nitrogen and nutrients. To grow the plants need extractors, humidity control, a drying area, and halogen lamps which are switched on 24 hours a day. One plantation site, of 1,800 plants, in San Vicente de Raspeig, costs 9,000 euro per month for electricity.
The Ak-47 seed is particularly popular and costs around 800 euro for six. This strain is very productive with good results in just a few weeks. It has an intense odour, with a strength 15% THC, which is the part of the plant that is sought.
On the black market, a gram is now priced at around 6 euro, and a single plant can produce half a kilo.
