UK Police have busted the first magic mushroom farm since a Watford man was found growing them in 1998.

Officers from Cambridgeshire Police raided a house in Huntingdon in the early hours of yesterday morning Tuesday, March 9.

Police say it is the first magic mushroom factory believed to have been discovered in the UK for over 20 years.

The last known magic mushroom factory to be busted was in 1998, when then Watford resident Richard Wilson was jailed for a year for growing the drug in a sophisticated factory inside an industrial unit.

Police stumbled across Mr Wilson’s enterprise when they discovered a secret hole in the wall of an industrial unit in June of 1998.

It opened into a labyrinth of smaller rooms clearly set up to cultivate mushrooms.

Experts were called in from Kew Gardens who confirmed the species was Psilocybe Cubensis, from which it was possible to extract the class A drug Psilocybin.

The growing apparatus said to be very sophisticated, with a special polythene sheeting forming a membrane for the harvesting of mushrooms.

Heaters and humidifiers had been installed to maintain a constant temperature between 25 and 30 degrees centigrade.

There was a soil room and a propagating room, jars, laboratory dishes and thermometers.

Magic mushrooms have been classified as a Class A drug in the UK since 2005 - and it is therefore illegal to have this type of mushroom for yourself, to give away, or to sell.

In Cambridgeshire, the grow operation was not quite as sophisticated, but officers did also discover a cannabis factory inside the property.

The total street value of the drugs growing inside the property was over £5,500 - and police also seized cash and other drug paraphernalia.

A 26-year-old man and 24-year-old woman from Huntingdon were arrested on suspicion of possession with intent to supply drugs, production of cannabis, producing a controlled drug, money laundering and possession of drugs.

They have since been bailed until April 6.
