February – March 2014
Plants: Mallow, Sea Buckthorne, Sapodilla, Blackcurrant, Gooseberry.
Creatures: Utah the Doggle (a peculiar cross between a dog and a fraggle)
In this instalment, I work on improving the food pond by adding a DIY swirl filter made from a dustbin / trashcan and a simple gravel filter / growbed for kangkong, watercress and other plants that don’t mind being constantly flooded. There’s still room to expand with more beds in the future, as well as floating island planters. The medium for the growbed is volcanic rock gravel from my land. The swirl filter uses a modified laundry basket lid at the bottom, and although I forgot to show it in the video, there is a T connector at the end of the hose under the laundry basket lid to send the water in two diferent directions.
I also show off a quick bench I made out of a pallet, some uses for rocks including simple terracing, and I release some geckos into the house for pest control.
Putting my new camera to use around the homestead. My new pond should give me greens all year round, and when I have enough fish I’ll expand further into outdoor aquaponics & grow all kinds of fruit and veg in the water on floating foam rafts. If this experiment is a success, I plan to put more ponds between the trees in the orchard.
I made a path (hand-mixed concrete poured over a hacksawed rebar frame joined with wire) and new raised beds to go with it. Hopefully some of the visiting bees will take up residence in the very basic beehive I put together. It doesn’t have trays so harvesting of honey is a no-go, but bees need the honey they make to feed their young, so that’s just fine.
Mosquito fish are likely the best fish for hot climate aquaponics systems, especially if you’re not interested in eating the fish (tho they are edible if you’re so inclined). They can survive all kinds of calamities unfazed, don’t need a pump, breed like flies (they’re one of the few live-bearing fish), and even survive in a few cm of wet mud when the waterways here dry up in the summer. The ideal permaculture fish. Tho I’m trying other fish in the pond, I’ve kept mosquito fish most of my life and doubt anything can top them.
I sunk holed bricks and cages filled with stones in the pond to allow fry to hide. I also added some driftwood.
