I looked into this a few years ago in the states, and unless you have a pristine low cost water source and very low electricity costs, it’s difficult to produce at a scale that makes entry and competition viable, let alone recession proof.
There are other expensive issues too— scaling your harvest processing capacity and packaging, pest control and waste handling, organic certification or hydroponic system maintenance… ultimately even with automation or going back to basics I couldn’t make it make sense as a standalone business. It needed to be part of a larger enterprise that had similar input and uses for the unsold or byproduct outputs. I determined there were better margins in selling preparedness kits and aerogarden style micro greens setups.
How anomalous is this? I’d personally want to have an overhead camera or something I could trigger myself to show I packed things correctly if I was a worker at a place where this was common.
