Thank you for the excellent post.
I have a book, "Hydroponics, the Bengal System", by Sholto Douglas, 1955. It works, there is zero runoff.
Green Mountain Harvest Hydroponic in Vermont is doing well. Fully automated.
I cannot believe the ignorant remarks by Freepers on any somewhat technical subject, where they know so little, they don't know what they don't know.
Makes us look like idiots for the possible new person thinking of fleeing the democrat party.
Maybe do a little online research before typing foolish gibberish?
It's funny you're mentioning an old book that contains very useful tech information that is very applicable in our contemporary times. I have a dozen old books that I acquired on purpose or rescued from being discarded that have served me well. In fact, they have been key in several hundred million $$$ of process design work relating to industrial water treatment over the decades. When I retired, I finally relented and got rid of most of my tech library but kept these dozen books. Hauling a thousand pounds of books when I moved was a real pain!
One of the books though is just a fun one (for me anyway) having to do with residential passive solar design written by Mazeris (sp). No fun doing this living in GA but was a blast using SW architecture and adobe construction common to NM and AZ.
