I'm quite sure hydroponics and be organic depending how you do it. But there is an issue for me with flavor, wholesomeness and sheer goodness. Hydroponic veg I can taste. So, I have this nose that snuffles out anything strange and the nose is the first thing important for taste as well. I taste that stuff .. there is what I can only describe as a flatness - the taste is not deep and lasting. It is different with aquaponics and somehow the food tastes better.
Anyways .. just my view on this.
And inside of my fortune cookie was this tiny ad:
Solar ovens, haybox cooker - What would you build to go with a rocket oven?
