Geez Adam, from a mower man's point of view...... are you friggin crazy.
All those edges and crap to mow around..... ffffttttt.
haven't finished yet at some stage i will get some deco and put a mow strip along the wall and around the patches.
still as is only takes 1/2 hour to mow and snip.
Nice.
We are thinking of getting an aquaponics system.
i was trying that myself,
when i had the fish pond 2000ltr in the middle it had a watering system to water the veggie patch. but i kept getting bad algae plumes, so i put the roof on to reduce the light, to no avail.
had that system running for over 3 years, and the fish got quite big 30+ cm (4-7cm when i got them)
most of the system ran off 12v solar but also added a 240v bilge pump on a timer.
this added heaps of oxygen and flow to the water and the fish seem to like it too.
i then derigged that and turned it into a micro eco system, with turtles and fish but a lot less water about 800ltr.
had that running real good, then someone pinched one of the turtles (would tell the kids it was hiding)
it had a water plant filter that ran down a waterfall , then ran through a gravel filter and water the plants.
in both systems as i watered the plants i would then top the pond back up.
i do believe the aquaponics system you buy / make, would be a lot less maintenance compared to what i had.
but mine was more about the visual than practical.
