always thought things like this is cool, unfortunately its still expensive sometimes. Im currently doing aquaponics with 2 goldfish in a 30 gallon bucket and about sixty heads of lettuce. So far so good
Thanks for the very interesting post sean, glad this was made a topic. that's in a greenhouse btw. I do disagree with some things relating with plants being planted in the soil. Plants in soil are truly organic if you don't use pesticides like me, I live on a 30 acre farm, half wooded, half mended farmland. As I said in my greenhouse I do aquaponics because I know what I feed my fish, I know where they came from, I know where this lettuce for example is growing at and where its nutrients is coming from. on a diy level this idea is great and can be used (for example) by sean and many other hobbyists. on an industrial level this would be a so/so idea, as the water is being stored and pulled most likely from what location? that would pretty much be unknown and ignored.
weather its in a big bucket or the ocean, people wouldn't know and that is my main concern with what I eat and it isn't payed attention to much. Farming itself is expensive, people think that if the grid goes out they can plant a couple seeds and live on that forver. sixty heads of lettuce will feed a family of four for little time maybe a month. I am a tradinitional farmer and enjoy sticking to the "natural ways" and I know that sounds hippie like which im not believe me, but its true. People need to pay attention to where they're products of which they eat originate from and come from all the way down to the roots. I eat fish crap when I eat that lettuce because that's what is making that grow, or taking part in it. When you grow tomatoes in the ground your eating dirt lol. When your growing thins in the air, well. Your eating water. I will admit this method doesn't provide as much flavor in the food itself as much as other methods would. another factor is that when plants grow in the ground, or on the earth. The soil is constantly being mended by the roots of the plants, and the soil is constantly being built up by the plants die off. such as leaves, dead roots, etc. If you (and this is again on industrial levels) used that idea in the video on an industrial level, they would most likely throw dead leaves if any away and burn them later on. The earth would have a con then.
Sorry this little write is zig zaging all over lol and there is probably some spelling errors.
that was the farm part of my opinion lol
I love your idea of doing this with emersed plants to me that's a fantastic idea and im saying you should do it all the way, plants in the hobby are weeds from a forest in Africa that we pay up to hundreds of bucks for to profit someone else. which I understand but they could be much cheaper, maybe sean youll become the next dennerle!? lol. Good luck on your journey of aeroponics(spelling?) with aquatic plants. Grow emersed grown ones though make sure they aren't submersed only. and make sure when you cut holes for the plants in the "whatever material your going to use to hold the plants" fits the plant size and rhizome or, base. also I suggest for this using horticulture lights, fits the purpose!
