    I don’t know anything about this subject with the exception of a video I watched a while ago mentioning that most hydroponic startups end up failing because the cost is too high as you always need a specialist and you can only grow smaller plants/veggies there. This compared with traditional farms.

    Does this change that at all? I’m hoping it does as I’d love that hydroponics got much more financially viable as I honestly believe they’ll be our future considering global warming and pests as well.

      The difference here is in the efficiency of the system.
      And that this is an aquaponics system, which includes growing both fish and vegetables.

      After more than two years of testing, Prof. Gross’s system demonstrated 1.6 times higher plant areal productivity, 2.1 times lower water usage and 16% less energy consumption per kilogram of feed than conventional systems. His calculations suggest that upscaling to about one ton of fish will allow operation of the system with no need for external energy, less than 1% water exchange, negligible waste production as well as significant carbon sequestration.

      I don’t think this is applicable to backyard aquaponics. You don’t want to include an anaerobic digestion plant in your backyard project.

      Either you have no use for the Bio-Gas, or you use more than 10kg of fish can produce.

        I bookmarked this for reading later, so i hadn’t perused it yet. I would fall into that first category. I’m still really green in this regard. I usually spend a few years studying and learning before actually taking action, but this is all helpful info.

    It is cheaper to produce fish and greens of manufacturing is combining the production.

    The synergy of manufacturing processes increases profits and can be sold to consumers as reduction of energy consumption.
