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.
