A man has been found guilty but his co-accused acquitted over a $10 million cannabis crop in the Murray Mallee of South Australia.

Thomas Tigani, 61, has walked free from the Adelaide District Court, but his co-accused George Hatsiosifidis, 75, remains on bail ahead of sentencing.

A jury found Hatsiosifidis guilty of two counts of cultivating a commercial quantity of a controlled plant.

The court heard more than 3,000 cannabis plants were found at a property at Peebinga, between Loxton and Pinnaroo, in February 2011.

They were watered by a sophisticated dripper system.

The prosecution alleged Hatsiosifidis tended the plants and that Tigani supplied the land and irrigation equipment.

But the jury reached majority verdicts in Tigani's favour.

Submissions on Hatsiosifidis's sentence will be heard in May.
