"You bought new hydroponic equipment and extended the factory premises and built hidden rooms therein and moved the plants to these premises. You then took cuttings from those plants and grew other plants. By mid 2002 the plants were flowering, the results were better than you had achieved at Mickleham. You engaged Mr Rios to look after the plants on a daily basis.
Prior to September 2003 'Generally there were about 500 plants on the go.' From September 2003 there were 'About 2100 plants growing at any given time.' This continued to the date of arrest. There were some 2100 plants growing at the time of arrest. By that time, during the period the subject of this charge it is agreed that you had grown three previous successful crops which together with the crop discovered by the police made a total of four crops. During the relevant period the number of plants in each successive crop had progressively grown from a smaller number to 2100 plants which is said to be the capacity of the premises.
Without any pretence of precision, it is clear that during the relevant period you had grown and had in your possession for sale something of the order of 3000 to 3500 cannabis plants and that may well be a conservative figure. The number of plants required to constitute a large commercial quantity is 1000 and you had some three to three and a half times this number.
The trafficking continued, as I say, over a period of some two years and four months. It ceased only upon arrest and it was trafficking by way of an ongoing business. As one would expect in a business of this nature, plants were at any given time in different stages of development and maturity and size. The system was such that new plants replaced old as and when necessary, emphasising the ongoing nature of the business.
The hydroponic set-up at Tullamarine was elaborate and sophisticated, in part at least automated and highly organised, and no doubt expensive. The operation itself was extensive and could accommodate large numbers of plants. The premises included growing room, drying room, preparation room and so on.
There is no evidence led, of the street value of, for example, the crop of 2100 plants, but one's experience in these courts justifies the belief that it would be very valuable indeed.
Whilst I do not think that the size and quality of the plants grown or the yield from such plants defines whether the quantity of cannabis is a large commercial quantity, these matters are not irrelevant to sentence. They effect, for example, the potential for harm which a particular number of plants has within the community.
In this case, although the plants in question were not intended to be grown to a height of more than two to three feet, and even though there would be a certain failure rate with these, as with any crop, the evidence and the photographs exhibited show that at least the plants found by the police were healthy and flowering. The results achieved with new chemicals were 'outstanding'."
