With respect to the sun
I am in the Riverland SA so similar to you but bit further north
The sun at the moment tracks across the sky quite low
By December it will track parallel to its current track but will go overhead during the middle of the day
By February it will track over a bit to the south of vertical
Hope that makes sense and you can site your growbeds for the best use of sun
My system is under 70% shadecloth all year round and everything grows fine
Most plants need about 6hrs minimum sunlight to grow
What is blocking the light
Post some photos of your growbed site will help
You may be able to "reflect light" using something like plywood painted white to help a bit
Prune Trees if they are the problem
Raise growbeds up 2 metres not ideal but if its the only way you can get light might be an option this of course will require a stronger pump which will use more power.
I don't grow a lot of veg in my system through the cold season (water gets pretty cold)
Brassicas will grow but take forever and fill growbeds due to their size
I get best result from Garden peas and silverbeet (for the Chooks) through the cold season
Plenty of options through our warm / stinking hot season
You will find during the hot season its likely you will have enough light

Hi Ozzyrod. I think TCLynx is pretty close to the mark. You will need as much sun as you can get in winter and keeping Jades in Torquay is not doable without extra heating (and therefore $$$$$). The silvers and pandanus do fine. I used a 13mm x 100m polypipe solar heat absorber for the last couple of years which added up to 4C extra, but that is still nowhere near enough. Have you thought about replacing some of your shed roof with polycarbonate sheeting and building inside the shed as a greenhouse? I am in Altona and you are welcome to call in to take a squizz at my systems next time you're on your way to Melbourne.

Thanks everyone for the words of advice, and yes I have to go with the indoor system with some polycarbonate sheets aboce (two, see pic) and I now have a hydro light with 4 full spectrum globes in place above the 2 grow beds, (1 established, the other to be built, am doing the bell syphon today). As per advice I will stay with Silver Perch and Tandanus due to our climate here in Victoria. I would love to come by to Altona Nhibbo. I am actually going to Koroit Creek Rd Aquarium as I believe they have some good marine tank setups. Will PM you on that one one. Thank you. I will have posted some pics of the light in place and the progress to date when I get onto PC to shrink pictures to an acceptable size P.S I bought the light yesterday from a hydroponics supply place and it only cost $190, so I will see how that goes. Cheers Rod
