Finally finished my DIY hydroponics setup. It’s two systems in one: an AutoPot system and an NFT system, both cycling to the same big reservoir. I built a custom dosing system that is fully adjustable with auto mixing and PPM control. The pumps run on a timer and the whole setup is coded by me in Home Assistant. I 3D printed most parts and I have the files if anyone is interested. The spinach is still going strong after almost a year. I’m also growing tomatoes, strawberries, and asparagus.
