The men, aged 37 and 33, denied having anything to do with narcotics.
Suspecting that a property on a central Gothenburg industrial estate was being used to cultivate cannabis, police raided the place in August. They found three rooms behind a secret door. Two of the rooms were packed with cannabis plants.
The space was specially fitted with a ventilation system and lighting for indoor cultivation, and 14 kilos of cannabis had already been harvested.
Although both men were linked to the property, they said they had nothing to do with growing the cannabis.
The older man was sentenced to four years and ten months in prison, while the younger man received four years and eight months.
