Police discovered a large cannabis farm at a unit on an industrial estate in Heathfield on Friday (January 23), after being alerted by bailiffs who had visited the location.
Officers found approximately 2,000 plants at a unit on the Ghyll Industrial Estate.
Five different rooms within the unit contained around 400 plants each, all in various stages of growth.
Thang Cao Do, 41, of no fixed address, was charged with being concerned in the production of a class B drug and remanded in custody.
He was due to appear at Brighton Magistrates Court yesterday (Monday January 26).
Detective Constable Tod Stewart, said: “We have disrupted an organised and significant operation, preventing harmful drugs from reaching the local community.
“I would ask all members of the public to be vigilant, as both commercial and private properties can be used for the production of cannabis.
“Signs to look out for are covered over windows or curtains constantly closed, people visiting properties at odd times, for example to water plants, extractor fans in walls and a sweet, distinctive herbal smell.
“If you witness any such suspicious activity please email information to firstname.lastname@example.org call 101.”
