A man who used every room in a Dunedin flat – including the roof space – to grow cannabis has been jailed for two years and four months.

Dylan Pattison (26) appeared in the Dunedin District Court this afternoon after admitting cultivating the class-C drug.

When police raided the Union St address – in the city’s student sector – on July 13 last year, they found 353 plants at various stages of maturity.

Crown prosecutor Richard Smith said it was a hugely significant grow which could have yielded nearly $500,000.

Pattison said he initially got involved to grow solely for his own use but “got greedy”.

Judge Michael Crosbie was amazed by how much cannabis was inside the house.

“It sounds like people could’ve got high from just walking past it,” he said.

The court heard Pattison was the first of three to be sentenced in relation to the commercial weed-growing syndicate.

He started renting the $400-a-week property in March last year and police got wind of the illegal activity the following month.

By July, they obtained interception warrants which revealed more of what was going on between those involved.

Pattison was primarily responsible for watering, fertilising and harvesting the crop, which was in different stages of growth in various areas of the property.

Initially, the four bedrooms were used for growing cannabis, but things quickly escalated.

On July 11, a window of the house was broken in an unrelated incident and plants were moved into the roof space.

Sophisticated equipment was purchased to ensure the crop was successful, the court heard – controlled lighting, air-flow systems, carbon filters were all installed.

Police estimated nearly $15,000 would have been spent on paraphernalia.

Defence counsel Sophia Thorburn stressed there was no evidence of significant financial gain for her client. Any money he made, she said, went to supporting his partner and four children.
