Episode-1640- Aquaponics for High Density Food Production — 2 Comments

  1. I found myself nodding in agreement with most everything Chad and Gregg said. My system is made from 3 250gal ibc totes which is a good way to learn the ends and outs of aquaponics. As with anything in Permaculture, the types of plants that will do well has alot to do with your location. Here in Central California, I’ve had mine set up for 3+ years in a greenhouse and enjoy experimenting with different plants in the gravel beds. Some of my interesting successes have been Yams (for the leaves), Celery, Jerusalem Artichoke, Peas, Potatoes and Onion starts. The celery is unique tasting in a good way. To successfully grow potatoes, I had to keep my seed mostly above the water line and let the potato choose to start tubers under the water line.
    I have found that tomatoes and cucumber plants grow well but produced very few fruit. Lots of bosoms but most fell off. It was probably due to a mineral deficiency. And yes the roots can be overwhelming on the tomatoes.
    As far as pests go I was having problems with red spider mites wreaking havoc but early this year I installed a mist system over the grow beds and the added humidity has done wonders. I haven’t seen any mites or white fly this year.
    I thought your guys interview was very informative and gave anyone new to aquaponics an accurate portrayal of what to expect. Good Job.

  2. I haven’t listened to this podcast yet (apologies) but I hope to. Two nights ago I got a renewed interest in aquaponics. Brought it up to my permaculture group last night and they don’t think it has much of a place in permaculture, due to its reliance upon modern technology. They mentioned instead something called a chinampa, which I see has occasionally been mentioned by readers of TheSurvivalPodcast as well and even Geoff Lawton.

    After considering this, I see these offer a similar planting environment and should deliver about the same results with about the same effort but with less overall cost and without requiring any reliance upon modern technology such as plastics or pumps. Aztecs built them using knives, boats, and shovels, which is perfect for a grid-down situation.

    In a nutshell, the liquids seep up from the pond through the walls of the island via capillary action to the plants. It’s been claimed that this method is one of the world’s most productive. They could get as many as seven harvests per year, not counting the harvests from waterfowl and fish. Gee, I’m sure glad those smart Europeans helped those nasty Aztecs get rid of their crude, primitive agriculture! Why aren’t we doing this more today?
