backyard aquaponics (Canada)
Hubby and I started this little aquaponics project last summer using the flood and drain method. We managed to grow quite a few things, but most ended up being fed to the chickens. Aquaponics is the greatest way, to be self-sustaining. It uses 90% less water than conventional farming, in fact you hardly ever need to water. It???s a combination of hydroponics and aquaculture; you can grow fresh organic herbs and vegetables as well as provide fish for the table (unless you are using goldfish) year-round, indoors or out. Water from the fish tank is pumped up to flood the grow bed where the clay pebbles and beneficial bacteria converts the fish poop into nitrates to feed the plants. The plants filter and return clean water back into the tank. The pump runs on a timer, so you never need to worry about watering. Just feed your fish daily, (also on a timer), and every now and then, top up the water that has been lost through evaporation. It can be a small set up for kitchen herbs, or large scale production. Kits like the ones from Earth Solutions can be purchased ranging from a few $100 to $1,000???s. Or do-it-yourself like hubby and I did.
