I have been browsing this forum and seeing a few topics here and there on both hydroponics and aquaponics systems. This just happens to be a topic I have been doing extensive research on, in recent months. I had a choice to go with either, but chose aquaponics for two reasons. The first reason is to have a second "crop" to help sustain us, and to have something to trade with others in the area, if necessary. (I would much rather barter, than to buy and sell for cash.) The second reason is, to see if I can create a 100% self-sustaining ecosystem, with little interference from me. The fish should provide the nutrients for the plants. The plants, in turn, will provide clean water for the fish. I believe that is how it is, anyway. I have already sourced Black Soldier Fly Larvae (BSFL), Duckweed, and other dietary needs for the fish (Tilapia). I will also put some Red Worms in my grow beds, as well as creating a worm digester. They may also be something the fish like to consume as well. By the way, if you don't know about them already, research Black Soldier Flies. They are great for both fish and chicken food, as well as helping you process your compost bins. They also seem to be territorial, in that they keep other flies away. They also have no interest in food as adults. So, unlike house flies, they are are easy to tolerate. My g/f has 2 hectares (~5 acres) of land here in Cambodia. It already produces rice (rainy season) and sesame seeds (dry season). I want to repurpose most of the land and do something more with it, especially wanting it to produce less water intensive crops. Not to mention, this is more than enough land to start a small aquaponics system on. So far, she seems happy about it. And, as they say, "Happy wife, happy life." Part of what we have begun doing with the land, over the past two years or so (we have been together about three years), is to raise (Silkie) chickens. (We failed miserably and lost an entire flock prior to then.) Also, she had some cows and ducks when I came into the picture. We also want to add some pigs, maybe some goats, to expand our farm. If this works out with the aquaponics, we may actually expand the system. After the initial setup costs and once it is up and running on a full head of steam, an aquaponics system should be fairly self sufficient and low maintenance.

Or, if not to become self-sustaining, what, if any kind of farming do you do as a hobby?
