For the first couple of years he spent thousands of hours struggling to learn programming languages to automate his backyard mini-farm. Then while speaking at an international conference (along with Eric Maundu and Rob Torcellini, he’s among the elite few experimenting with aquaponics and automation) he was introduced to APDuino(open-source firmware for aqua- and hydro-ponics).
APDuino allows Kretzinger to read the sensors in his garden without any programming. Now Kretzinger’s garden can send him tweets or Facebook updates if something is going wrong and Kretzinger can adjust the water flow, pH and temperature from a smartphone.
