I maybe Wrong, But if I am Designing a System like this to Grow Plants...There is a market For What You Do Not Need. And that Would dictate The What you Would Grow. The Fish are my Question.
if my Maths is off a 6 bed Grow would Need about 50 in a Season, With the possibility to Set up a Beeding System that adds to the Nutrient pool; Controlling the Growth with Different pipe Sizes....Meaning in a years time you Can have at least 4 Bed ready to Harvest Something Every 4 weeks...Now thats what my limited knowledge...
So my real question is What Can You Do With a Supply of Fish that you Can Guarantee 30 or more pounds a Month...
