Arjan Hasa, 23, and Vasjan Bali, 26, and were arrested in Mill Bank, Wellington, following a tip-off to police on September 11 last year resulting in the discovery of 167 plants.
Hasa, of London, and Bali, of no fixed abode both pleaded guilty to production of a class B drug and were jailed for 15 months and 13 months respectively on January 22.
The pair returned to Shrewsbury Crown Court on Tuesday for a proceeds of crime hearing where the authorities had hoped to recoup any money made by them from the criminal enterprise.
However, the court was told that neither had any assets.
Miss Holly-Louise Kilbey, prosecuting, said: "Following a police investigation neither of the defendants have any available assets. There are only nominal benefits. It would not be in the public interest to pursue those."
The court heard that £30 in cash from Hasa and two mobile phones were seized at the scene.
Judge Peter Barrie revoked the proceeds of crime confiscation order previously made when the defendants were sentenced. However, he ordered the forfeiture and destruction of the phones, the drugs and the equipment. Plus the confiscation of the cash.
