Crops can blight, animals can get diseases. I don't know much about hydroponics but I know that bacteria are a concern. What food source is the most reliable, the least likely to produce less food than expected?
Aeroponics, under a controlled greenhouse environment, is technically the most stable food production method, assuming you have the ability to maintain the systems supporting it, and of course a good knowledge of a particular plant's requirements and growth habits.
Pros:
Water Efficiency: Uses up to 98% less water compared to traditional farming.
Space Efficiency: Can be used in vertical farming setups, making it ideal for urban areas.
Growth Speed: Crops can grow faster due to higher oxygen levels and nutrient delivery.
Reduced Pesticide Need: Since plants aren't grown in soil, there's a lower risk of soil-borne diseases.
Aeroponics, when done correctly, can yield impressive results in terms of growth speed and resource efficiency compared to traditional farming.
Can vouch. I don't have an aeroponic setup, but I do have a hydroponic setup. Lots of reading has led me to aeroponics, especially high pressure aeroponics (HPA), although I don't have the means to set this up myself at the moment. Reduced water and land use plus higher yield and if you grow indoors or in a greenhouse you get less pests. Seems like the best possible option for growing food sustainably
