The U.S. Attorney's Office in Springfield said Monday that David Aaron Neblock also was ordered to pay more than $52,000 in outstanding taxes because he'd filed false income taxes.
Authorities say more than 750 marijuana plants were seized in July 2012 from a warehouse in Bradley, where Neblock grew them with artificial lights and an irrigation system.
Neblock also will forfeit a Kankakee home bought with proceeds from his marijuana-growing operation. Prosecutors say he bought the house by submitting a false loan application that claimed he was employed at various businesses and had received an inheritance.
Neblock has been in federal custody since pleading guilty in January.
