Exactly. It's not practical and unless something is practical, cheap, conventional, and low maintenance.....I don't want any part of it. Case in point - I have some friends who have a very large aquaculture project going, I mean big. I think they're nuts. Why? Aquaculture is not practical. Like all idealogues, they don't even know what minerals they're feeding their plants. I just groan when they answer "I don't know" in response to my questions regarding plant nutrition, "what minerals are held in solution?" This after spending hundreds of thousands on tanks, fish, plumbing both water and electrical, greenhouses, etc. And they think they can get rich selling basil!
Live and learn.....
