Two Vietnamese men have appeared in court over a massive cannabis-growing operation discovered in Kirkby.
Ly Quang Nguyen (19) and Nhi Van Phan (27) appeared before magistrates in Mansfield where they were both charged with producing the class B drug.
The pair, who were in custody and needed a translator, did not give an address or enter a plea during the short hearing.
It was deemed that the offences were so serious they need to be heard at crown court.
No application was made for bail and the pair are due to appear via video link at Nottingham Crown Court on 22nd July.
Prosecuting, Robert Carr, said that more than 1,500 plants had been found at the site on Unity Road on the Lowmoor Business Park yesterday.
Mr Carr said it had the potential to produce 130kgs of cannabis with a street value of more than £900,000.
Police had raided the old warehouse after receiving a tip-off from the public.
Along with the plants, they found huge amounts of heating and lighting equipment, and stacks of bags filled with fertiliser.
The plants, most of which were ready for harvesting, were found in nine separate areas in the old warehouse and across two floors.
Inspector Glenn Longden, of the Ashfield North policing team, said the discovery was the biggest he had ever known in 25 years working on the force.
Officers from Nottinghamshire Police headquarters were drafted in to help clear away the plants and equipment.
