An illegal immigrant who acted as a gardener for a £125,000 cannabis farm has been jailed for 16 months.
Son Van Trinh, 39, paid £25,000 to be transported from his home in Vietnam to the UK.
Preston Crown Court heard married Trinh and his family were suffering financial difficulties in Vietnam so his family supported him to leave the country, leaving his family behind.
Trinh was taken through Chechnya and into France, before being brought to the UK in the back of a lorry.
When police raided the house in Waverley Road, Preston, on November 19, Trinh had no idea where in the country he was and seemed frightened and confused.
Inside the house was a sophisticated cannabis farm where 319 plants were growing.
The attic and upstairs rooms were fitted out with hydroponic equipment, lighting, thermometers and heat lamps.
In one room was a mattress on the floor where Trinh slept.
The court heard Trinh had been in desperate need of food and accommodation and had been taken to the house by people he refused to name.
Trinh, of no fixed address, gave no comment when he was interviewed by police, but pleaded guilty to cultivating cannabis at Preston Magistrates Court.
Judge Graham Knowles, sentencing, said: “You were found in a house where there was what police rightly described as an expertly prepared cannabis farm. Your living circumstances were that you were living with only a mattress by way of furnishing.
“You were taken to the house and told you would be given accommodation and food.
“You inevitably had some awareness and understanding of the scale of the operation as you tended to the plants.
“You were engaged maybe by pressure and coercion, but it is probably more right to say that you were involved through naïvety and exploitation.”
