Climate change poses a severe threat to food production, making it imperative to find sustainable methods. One such method is aquaponics, which grows fish and vegetables together. Now, Ben-Gurion University of the Negev water researchers have offered a proof of concept for a new closed loop system that produced more fish and vegetables while using less energy than conventional systems.
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.
You can grow larger plants in hydroponics, but the current setups really only make sense where land costs are at a high premium, thus you end up stacking plants on top of each other with artificial lighting, and as a result there is not much space for larger plants.
