55 There was substantial corroboration of Ewings' evidence to the extent that I am satisfied that not only is the verdict of the jury unassailable, it almost certainly was the correct one. I will not deal with all of the evidence which corroborated the evidence of Ewings, but will mention some of the most probative and material of it. A substantial amount of marihuana was found by the police being dried and processed in premises occupied by the appellant. There was a substantial body of evidence that Indian Hemp had been and was being grown by hydroponic methods, and the appellant was found in possession of hydroponic equipment. Electricity accounts incurred by the appellant revealed unusually high consumption of electricity, consistent with a large scale hydroponic cultivation of Indian Hemp. Telephone records revealed many telephone calls between the appellant's telephone and the telephones of those involved in the growing and/or trafficking operation. At 78 Bathurst Street, where Indian Hemp was being dried and processed in the premises occupied by the appellant, $34,000 in cash was found hidden in his motor vehicle. In addition, a bundle of $9,620 in cash was found at his home, together with a slip of paper stating "35 @ $275 = $9,625". (Ewings gave evidence that cannabis was sold for $275 per ounce.)
