Question: What are the differences between aquaponics and aeroponics? Which one is more reliable and which do you think will have a greater impact on the way food is grown?

I guess what you are talking about is a growing environment that is tilted in a more vertical plane than straight out in a field. Typically this would need to be in a controlled environment like glasshouses? But I am not sure on the difference between aero and aqua. Basic plant physiology requires water for plants to function so aero by itself seems limited. We know how to control environments very precisely for maximising plant growth. An interesting aside. There is a thing called thigmomorphogenesis or rubbing stress. In controlled environments there is limited stress from winds, dust and other plants. Thigmomorphogenesis can enhance flavours in tomatoes and make plants more resilient.

Hi David
In aeroponics plants are suspended in air and roots are sprayed with nutrient-rich water.
In aquaponics, plants and fish live together in water and it is a symbiotic life with the fish feeding the plants, and the plants cleaning and filtering the fish’s environment.
Aquaponics is more relaible and suatainable and will have more impact.

Hi davidmcafee,
I think you mean hydroponics not aquaponics. This procedure refers to the culture of plants where their roots are immersed in solution (water + nutrients). This solution is not stagnant but often recirculated. Aeroponics is basically the same thing but instead of a bath, a fine mist of solution is applied to roots routinely which generally hang in an enclosed container. the high level of aeration (O2) around the roots encourages strong growth of the roots. This approach requires more technology as the plants can dry out quite quickly if the misting system fails.
Both systems are used for the production of food. However the hydroponic method is the most widely used system and probably the most reliable. I imagine we’ll see more hydroponics in agriculture to manage environments for critical high value crops.
