this is neat.
I thought so. Year round vegetables, even in the winter.
As an agriculture teacher I practice hydroponics for some years...the chemical nature of it is bad, checking the pH weekly etc....
Than I tried organic aquaculture, which is similar to hydroponics....you use the water and it is filled with manure, the water is passed over crushed limestone rather than perlite, the water is always a pH 7.5 as the acid eats the limestone naturally. The manure supply I used was from geese entering the water daily for a swim and they poop in it....The system works like a treat and after several years the limestone medium stats looking like humus soil....
I am considering attempting a similar system, but with tilapia, so there is another food source side by side. I would like it if you could educate us further in this post. Your wealth of knowledge would be beneficial to those of us who want to start off with aquaculture. I suspect you could even generate blue prints, and help us with insulation techniques for the cold weather. I think it would beneficial to those of us who bad soil (like me) and others in colder climates who need to insulate for sharp temperature drops. I was considering putting a set up in the sunnier part of the property and trying to solar panels to keep the thing eco-friendly.
