Automated Hydroponic System Build (2020)
I have been in the aquarium hobby in the past, so when I started looking into hydroponics, for me the natural outcome was to also look into aquaponics[1].<p>What I like the most about aquaponics (and recirculating hydroponics) is the sustainability aspects, it is an almost completely closed-loop system, with relatively small external inputs compared to other farming methods, and extremely small water requirements (due to the fact that water is continuously recycled).<p>Two bits of info about aquaponics that not many people know:<p>1. it is possible to have aquaponics systems in a vegetarian context: in many cases the fish is not for human consumption as food (in large commercial systems this is usually koi that is sold as ornamental fish[2a], in smaller systems goldfish kept as pets[2b]).<p>2. there are aquaponics systems that don't require access to electricity, in particular the iAVS system (a.k.a "sandponics") was developed with subsistence farmers that had no electricity access in mind, it doesn't require water to be pumped continuously, rather you are only required to manually recirculate the water a few times a day which can be achieved with a bucket or other low tech solutions[3].<p>[1] <a href="https://en.wikipedia.org/wiki/Aquaponics" rel="nofollow">https://en.wikipedia.org/wiki/Aquaponics</a><p>[2a] <a href="https://www.pvrkoicentre.com/pages/aquaponics" rel="nofollow">https://www.pvrkoicentre.com/pages/aquaponics</a><p>[2b] <a href="https://farmingaquaponics.com/caring-for-goldfish-in-aquaponics-systems/" rel="nofollow">https://farmingaquaponics.com/caring-for-goldfish-in-aquapon...</a><p>[3] <a href="https://garydonaldson.net/home/iavs/" rel="nofollow">https://garydonaldson.net/home/iavs/</a>
