An Australian national has been arrested in connection with the raid.
The residence, next to Vila East School, was under police surveillance for the last two weeks.
Police said the house was used as nursery for marijuana and that the plants all in pots were watched to grow to their full maturity stage.
While no further details were made available by police, insiders say the entire house was used up for different processes and stages from seedlings phase, transplants, and vegetative stage up to the flowering stage.
Cannabis can be grown indoors in a soil-like medium under artificial light, adding fertilizer when the plants are given water. Cultivating cannabis indoors is more complicated and expensive than growing outdoors, but it allows the cultivator complete control over the growing environment. Plants of any type can be grown faster indoors than out due to 24-hour light, additional atmospheric CO2, and controlled humidity which allows freer CO2 respiration.
Plants can also be grown indoors through the use of hydroponics
To grow plants indoors, a growing medium (e.g. soil or growing substrate), water, nutrients, light and air need to be supplied to the plant (with the exception of aeroponic cultivation, in which case a growing medium is not required).
In this case, police found about 60 plants, grown on coconut husks inside the flower pots.
No information is available on the street value of the plants seized.
The plants were moved to the Central Police station in Port Vila yesterday then moved to another location.
Police are also looking at the possibility of whether this latest raid has any connection with an alleged illicit drug manufacturing lab found behind Mele Beach on the outskirts of Port Vila.
Another Australian was arrested and released on bail in that matter.
Investigations are continuing with the assistance of the Australian Federal Police forensic officers.
